Redmond reveals Hyper-V 2016 beats vSphere's RAM and CPU count

wonder how they tested more than 12TB

I see Dell has a 12TB system, HP has a 6TB system (expected their 8 socket box to go higher but it tops out at 4TB). Only x86 system I could think of that may go higher is SGI UV (though officially apparently only supports a couple variants of linux).

All of my vSphere systems are 384GB, not too excited about going far beyond that still right now. Though I'm not running something like SAP HANA either.

HPE was in the report

From what I saw in the previous el reg article(not interested to register to read the original report from DCIG), 3PAR is the go-to market system for HPE, and there are no current 3PAR systems that scale to less than 500TB as of about late September 2015(announced earlier but not shipping till later in September I believe).

Re: Nothing beats real applications - BUT

Oh, don't even get me started on load testing :)

In my 13 or so years working at various SaaS-type companies I have never, EVER seen a valid load test against an application(across many companies). Every test has always fallen far short of real production load.

My favorite test was at an advertising company I was at, the front end app was basically pixel tracking, so very light weight, and no external dependencies beyond the single server that the app lived on. The "performance" testing we did there was basically shift enough production load onto a single server until it could no longer keep up, and the load balancer automatically routed requests to other systems when the system under test went down. At the peak we managed to get about 3,200 HTTP transactions a second from a server(disk I/O bound), I assume by now(that was many years ago) they probably use SSDs or something to help with that.

Worked really well, but obviously very dangerous to do in a more sophisticated environment with shared components like databases or caching servers.

My first SaaS job over a decade ago it was semi routine to have to double production application capacity after a major release (and of course we didn't plan for it, so we would order HP servers and have them shipped overnight). At some point the need to double stopped but it was there for quite a while.

As a 3PAR customer for the past 10 years I say I do want another synthetic test, the more data the better, especially if it has full disclosure requirements like the SPC seems to.

POCs are very time consuming to do, many vendors won't do them at all (NetApp refusing a POC 10 years ago is why I became a 3PAR customer, and NetApp again said 5 years ago it would be very difficult do do a POC(not that we could do one anyway but I was curious what the situation was with them and POCs at that time)). I'm sure it's difficult for other vendors too(though the startups generally don't have an issue with POC since they want customers so badly).

If you got your list down to 1 or 2 systems to test then maybe it is realistic to try to do real workloads. But I go back again to my 3PAR experience with 3PAR saying several customers wound up feeling they were "forced" to buy the system because it was in production(and working well). For me when I did my first 3PAR evaluation (small E200) I made sure it wasn't even in the same data center as our production stuff, I didn't want to get stuck in that situation.

When the company I am at now did our initial data center specs(5 years ago), we literally had zero equipment. No racks, no servers, no storage. Nothing to do a POC on(everything was "cloud" based at that time). So impossible to do a POC (in any reasonable time frame anyway).

Synthetic tests are far from perfect, even though some people claim "SPC-1 is "broken"" there's no other alternatives at this point.

If there's a dozen systems or more to choose from POCs from everyone is just crazy.

Fortunately for me my choices these days are pretty simple, 3PAR is good enough, fast enough, cost effective enough, and most importantly mature enough for everything I need (well except File storage, looking to do a small real Isilon POC soon, after testing their Isilon SD edge and having it implode in my tests due to the software architecture they have(their hardware works around some of that with metadata acceleration not available in the software product, something EMC staff seemed to know nothing about when they pitched SD Edge as being basically identical to what runs on bare metal). Wish HP had good file services...and data compression for SSDs(sort of feel like I should give up asking what the status of that is at this point after 4+ years of asking for that feature).

Re: Careful TP

I want it to work too. Which is why I am on vsphere 5.5 with .net client. No plans to upgrade. I stayed on 4.1 until past end of support. I've had to file maybe 1 or 2 vmware related support requests per year over past 5 years.

As someone who has been using linux as their primary desktop since 1996, I hated the .net client for a long time. Till I saw the flash client. Even for small scale it's just too slow.

I'm happy if the new HTML5 client works better, though even if it worked perfectly it wouldn't make me consider upgrading for that. .net client works fine for me.

My normal interaction with vsphere is running a windows VM on linux then running a xenapp client to a xenapp server running vsphere (xenapp on linux and vsphere don't mix well in my experience ). My two vsphere servers are 3000 and about 8000 miles away from my desktop.

I've been a loyal vmware customer since 1999, I don't see that changing but I am firmly in the vsphere only camp when it comes to servers at least (also use vmware workstation on my systems too).

Citrix re did their netscaler interface in html5 too (before it was java only). Html5 interface is terrible. So slow compared to the java UI. Once again at first glance I hated having to use java, till I saw what they did to "fix" that problem. Then I wanted java back.

Re: Flaw is in the qualifications

haven't bothered to look at the report myself but if the above is accurate it would exclude any currently shipping HPE 3PAR systems as the lowest end model 8200 supports 750TB raw.

But yet apparently the report includes HPE so I would assume that means 3PAR.. so maybe another double standard.

IPv6 now faster than IPv4 when visiting 20% of top websites – and just as fast for the rest

Nate Amsden
Silver badge

Re: 20% is not noticable

I just moved away from the bay area for a 50% drop in housing cost which was approaching 50% of take home pay.(up over 1000/mo in past 5 years).

You joke like 20% is a lot, it's all relative of course. I routinely tip 30 or 40% for good service. If it's really good maybe I go 60 or 75%. On a few occasions go over 100%.

My mother asked why I wasn't pissed off that the government takes roughly 45% of my pay. I told her that's just how it is. Doesn't really bother me since it's pretty consistent (unlike housing costs).

My new apartment has internet speeds that are 10 times faster than my previous apartment for about the same cost. I will notice that for sure.

Re: Time to learn

one of my ISPs is Hurricane electric (co-lo in fremont facility just a 1U server though I have a 3rd of a rack, power limits prevent me from using more though). They asked me if I wanted IPv6. I said...NOPE. don't need it. They did give me some IPv4 IPs, I think I got 6 or something (running vSphere on my server with a few VMs on it, also running an openbsd firewall inline in front of the VMs which does NAT for other VMs that don't have external IPs). I do like the 100meg unlimited connection I have with HE though, I proxy most of my HTTP/HTTPS traffic through the colo.

I see what you say about IPv6, but if I am going to play around with things I'll go play Fallout 4 or something, playing with IPv6 "just because" doesn't sound remotely fun or interesting to me.

20% is not noticable

20% of anything generally is a rounding error for me. 20% faster, 20% cheaper, 20% more efficient.

I just checked my AT&T phone again, it is not roaming, and is assigned an IPv4-only IP 10.xx address. www.whatismyipaddress.com says I am coming through a proxy server(or perhaps carrier grade NAT maybe they don't differentiate). Never had a problem accessing things even with tethering.

I just spent 3 months in thailand, didn't happen to notice what my phone with a local SIM card was assigned if it was v4 or v6, but more than anything the latency(purely distance I imagine) killed performance, I managed to get somewhat better web performance tethering and going through a VPN and proxying my HTTP traffic through my co-located server in California, though not for geo-diverse sites).

Myself I have no interest in IPv6, I do not have any plans to deploy it on any of my networks, if it happens to get deployed in a transparent fashion upstream on my mobile or broadband connection I don't care since it is transparent (I do not make inbound connections to my phone, and any inbound connections to my broadband are done through a VPN established outbound to my co-located server so I don't need static IP and don't have to care about NAT that the ISP might be doing).

I figure if at some point I really need to support inbound IPv6 to the websites that I manage then I'll have that translation handled by the CDN (just like they already do things like SSL termination and TCP optimizations already).

The die hard IPv6 fans remind me of the modern web developers who want you to jump on the new thing just because.

I would put IPv6 up there along with Software defined networking(SDN) as something that can benefit large scale companies well(mainly service providers), but for 95% of the downstream organizations it provides no benefit.

IPv4 addresses are available, getting large blocks of them may be difficult, though every company I have worked for in the past decade hasn't needed more than a few dozen external IPs at most (even today not hard to get). Smart use of NAT and name-based virtual hosting(with good proxy servers - in my case Citrix Netscaler or F5 BigIP) goes a long way.

Now that SNI is pretty widely adopted that removes a large reason to need a big number of IP addresses on servers with multiple SSL certs(covering multiple domains so a wildcard cert wouldn't be sufficient).

Die hard IPv6 proponents say IPv4 is full of hacks and brokeness so we should upgrade because of that. The hacks seem to work fine, I suppose if you are directly suffering from those limitations then you should probably upgrade, myself, I really haven't had any pains associated with IPv4. For example the last time I was at a company that needed a site to site VPN with another company and we happened to have overlapping IPs so had to do 1:1 NAT -- that was literally 11 years ago).

Myself I don't do peer to peer anything and the VoIP solutions I have used seem to work fine with IPv4 and NAT etc.

So no pressing need to upgrade, I don't see a pressing need for many years to come(for folks like myself anyway).

Explo-Xen! Bunker buster bug breaks out guests from hypervisor

Nate Amsden
Silver badge

Re: Please be more critical of the Qubes project

I do not use KVM but did not believe the claim that it is a type 2 hypervisor, did a quick search and came up with

https://www.ibm.com/developerworks/community/blogs/ibmvirtualization/entry/kvm_myths_uncovering_the_truth_about_the_open_source_hypervisor?lang=en

"Myth #1: KVM is type 2 hypervisor that is hosted by the operating system, and isn’t a bare metal hypervisor.

This is a persistent myth, but the truth is that KVM actually does run directly on x86 hardware. People assume it is a type 2 hypervisor because one of the ways that it is packaged is as a component of Linux - so you can be running a Linux distribution and then, from the command-line shell prompt or from a graphical user interface on that Linux box, you can start KVM. The interface makes it look like it is a hosted hypervisor running on the operating system, but the virtual machine is running on the bare metal - the host operating system provides a launch mechanism for the hypervisor and then engages in a co-processing relationship with the hypervisor. . In a sense, it is taking over part of the machine and sharing it with the Linux kernel."

I assume the misconception is similar for those people that think Vmware ESX/ESXi runs on top of linux because they see linux messages on bootup.

(Vmware customer since 1999 - haven't seen anything in Xen or KVM that has gotten me interested in evaluating them as alternatives - Linux user since 1996 so not like I don't have experience with open source stuff)

Containers rated more secure than conventional apps

Nate Amsden
Silver badge

big caveat there

Anything will be more secure if you "do it right", whether conventional/legacy or containers. Many conventional/legacy systems could be much more secure without even thinking about containers but generally companies are too understaffed or under equipped to handle changes in the face of everything else that is going on at a given time.

For the vast vast majority of use cases simply having single use VMs is more than adequate, a reasonably secured base OS with one app running in it (along with whatever base services you might need e.g. ssh, splunk agent, monitoring agent(s) or something). The overhead is really minimal.

Of course there are crazy people out there that want to be spinning up and down constantly, which is just overkill for just about everyone else. Most workloads are not very dynamic in nature(coming from someone working in more or less SaaS services for the past 13 years across many companies, none of which I would consider were using "legacy"(or "conventional") applications).

Some people like to THINK they are dynamic but in most cases the amount of variability isn't very extreme at all to warrant overhauling everything for a fully dynamic environment(which is a massive investment).

There are exceptions for everything of course, no one solution fits every problem.

I do use containers BTW, in production even(for about two years now with good results). Though the containers are generic LXC containers(that to a system admin look more like a VM than what one might consider a "container"), not docker. Looking to expand on the use cases of containers after the success we have had. The main benefit of containers at my org is to be able to oversubscribe a host and have the containers be able to instantly scale up and down(because they have no restrictions on CPU) based on load(while removing overhead of a hypervisor and licensing costs of hypervisor). Of course we use only similar application loads for a given container host, and we have data that shows the likelihood of one system overwhelming all others on the host has never shown to be a threat in the past 5 years(or anywhere close to one).

For everything else it goes in vmware which is of course far more flexible with networking, storage, and resource limits.

Seagate axing 1,600 staff amid PC sales slump

Nate Amsden
Silver badge

Re: Seagate might invest in Linux to offset PC sales slump

Sounds like a pretty terrible idea, I say that as someone who has used Linux (and continues to) for the past 20 years on my desktops and laptops (currently Lenovo P50 with Linux Mint/MATE 17).

Seagate makes storage, changing gears to start making servers or desktops is just a bad idea, and trying to make desktops with Linux on them even worse.

People are obviously more likely to switch to Mac than Linux if they don't want windows 10. The more technical bunch like myself will refresh their computers before windows 7 can no longer be sold by OEMs (October 2016 I believe) to maximize the life of windows 7 (I dual boot though 99% of time is spent in linux, I do use a windows 7 VM for work related things as well while in Linux).

Back in the late 90s I too had high hopes for linux on the desktop, there was certainly a massive opportunity, but the community building the software kept shooting themselves in the feet (a practice that continues today, with no signs of changing - biggest issue is driver ABI stability in the kernel).

Then IOS/Android tablets came out and gobbled up that entire market opportunity that was there for Linux on the desktop. Of course Android uses Linux underneath but it's really just a shell, so to me I don't really count Android as "linux" it seems to share practically nothing in common (from my perspective as an end user) with what I get with my regular linux laptop or servers.

capacity licensing

is pretty old isn't it ? HP has had it with 3PAR for years, and 3PAR had it on their own for years before that. I have little doubt that EMC and HDS and others have it as well.

I don't think it is very common, but the option has been there for a long time.

HP even has a "Facility as a Service" where they will go so far as build you your own data center from the ground up(at the time 150kW was entry level) and operate it for you.

They also have a "Flexible Capacity" program which is sort of capacity licensing for severs/networking/storage(I assume basically anything data center related) as well.

Though I'm sure FaaS and Flexible capacity are not well known, when HP told me about them at Discover 2 years ago I had not heard of them myself.

Does it even make sense to buy a VTL today?

Nate Amsden
Silver badge

you referring to tape in general or VTL specifically?

Because to me tape in general is still useful. The distinction between OFFLINE and OFFSITE. Wouldn't want someone to fat finger a command and delete all data and all backups(or an attacker do it). With so many things driven by an "API" these days it's easier than ever, more so with cloud services.

Having to have a human physically insert a tape into a library in order to access it is appealing to me anyway. Not to say that tape is the only backup, having onsite (online), and offsite (online) backups are still very useful but as a last resort I still consider it a good idea to have offline backups as well, after being written to physically disconnected from any level of automation that would allow it to be destroyed remotely -- whether that is on tape or another medium doesn't really matter though tape seems like the most likely target.

Lenovo cries 'dump our support app' after 'critical' hole found

Nate Amsden

Re: Sigh

my real user review of the Lenovo P50 is it works ok(about $3600 loaded up including 3 aftermarket Samsung SSDs and 4 year on site support). 98% of the time in Linux(with a windows 7 VM for some work things), 2% of the time in Windows 7(bare metal).

I think if you don't want the crapware you most likely have to pick a small OEM that installs vanilla software. For me it was more important to have on site support so I wanted a big name vendor. Previous laptop was toshiba (bought in 2010), worked fine though support was a year expired and I didn't want to risk my primary work machine being without support anymore.

Vulnerabilities like MITM to me are such a low threat level for most users it's just a knee jerk reaction by people a lot of times. Most technical folks will practice relative safe computing habits(I don't recall being infected with a virus or malware since roughly 1992), and hopefully not using (m)any public wifi access points to reduce attack vectors.

Less technical folks are likely to be compromised 100 different ways before anyone does a MITM attack against them.

I remember my grandfather before he died was apparently addicted to granny porn. He bought a Dell computer, would go to the porn sites, get infected, then after a few weeks or whatever the computer became mostly unusable, he would call up Dell, they would remotely reinstall the system, and he would go at it again(this was about 8 years ago maybe).

Windows 7 OEM end of sale date is coming up pretty quick (end of Oct 2016), and even now it can be difficult to find systems that will ship with it. MS has worked with big players like Intel to ensure lack of compatibility going forward with older Windows systems on new hardware, my company's PC supplier told me some horror stories about their customers rushing to stock pile compatible equipment before the hardware is no longer available(sometimes literally selling out while they had them on the phone).

LinkedIn mass hack reveals ... yup, you're all still crap at passwords

Re: Time to...

And move to what ? I have never had a facebook or twitter account but I do use linkedin. Though all of my info is "public" on linkedIn(just career stuff) so there is really nothing to compromise data wise(I believe linkedin had me reset my pw back with the original breach(?)).

I don't use linkedin for MUCH(though I am a premium subscriber), it has gotten me tons of career leads over the years(none of which I need right now), and really if just one of those pans out again in the future(little reason to think it wouldn't) it would of paid for itself right then.

In general I'm not a social person so being able to stay "connected" to the people in my career is handy.

I was thinking more along the lines of it shouldn't take much work to block such simple passwords from being used in the first place. I don't advocate requiring really strong passwords for something like linkedin, but people shouldn't be using 1234567 etc (unless I suppose it is a throwaway account or something). Maybe linkedin has already implemented this since this data is pretty old already.

sure, and you get all of the other pitfalls associated with ZFS along with it.

I think ZFS is a good file system(I even use it for basic file sharing NAS, with real block storage underneath), but I wouldn't ever really consider it as a storage platform. Not even oracle themselves can seem to get it right.

Salesforce claims 'record' quarter record at Oracle and SAP's expense

Re: Isn't it ironic

Maybe just to get better pricing on oracle.

I came across this while trying to find out what happened to all the noise salesforce made on postgres a few years ago

zfs to blame?

My experiences with zfs and corruption were very frustrating. This was on OpenSolaris. I was expecting a simple tool to just clean the corrupt blocks and mount the FS like any other fsck. But no it went to immediate kernel panic and a reboot loop.

With Oracle i would expect it to roll back trx that were bad.

I was at another company a long time ago where we had oracle corruption caused by both controllers in SAN failing at the same time.(the SAN admin blamed himself for misconfiguring the controllers to allow that to happen. To this day I can't imagine why a system would allow you to configure it in such a way) About 20hrs to recover from what I recall. Though we were still seeing the occasional ORA-600 or something error that indicated a corrupt part of the DB more than a year later. They had no really good backups either. They got budget for real standby servers after the incident though.

The tools to deal with zfs corruption were very immature at the time(maybe 4 yrs ago). It seemed to be generally regarded as voodoo to repair zfs corruption. There were things i tried at the time i don't recall what it was a while ago. Nothing helped all data lost.

Fortunately the data was a collection of backups so nothing really was lost other than downtime from the panics and tracing down the cause of the panics.

The system was a nexenta HA cluster that went split brain. Both nodes tried to write to the same volume and bam it imploded. Nexenta support immediately said we were fucked and to restore from backup. They refused to offer advice on the zfs tools used to try to repair the system.

After 2 or 3 incidents of this we disabled HA until we could find a replacement solution.

Dark net LinkedIn sale looks like the real deal

Re: Still Confused

I'm sure I'm not alone in using linkedin to keep track of business folks and former co workers. Sometimes I may reach out to one after a few years. Not everyone keeps a steady email address.

The other big use case is career opportunities. Though i have to tell recruiters i am not interested constantly I like being in touch with so many people that have expressed interest in hiring me or getting me hired so they can get paid.

About 10 years i worked for a company that was trying to compete with linkedin. I would laugh when i saw my personal network on LinkedIn at the time was more people than my company at the time had in their entire system. Company imploded about 7 years ago.

I almost never participate in the "feed" or whatever it's called the thing where people post things and commment on each other.

I don't use any other social media. I won't touch the linkedin app. Wants too many permissions.

Re: So Much hatred...........it leads to the dark side

If google didn't do what they did it is likely android would not be in the market leading position it's in.

Apple of course had millions of customers ready to gobble up the first iphones. What did google have? Not much. Microsoft was able to get full control of their phone platform (i think?) But of course nobody uses it.

Webos was the same. BB10 the same. Firefox OS the same (i assume).

For all the doom and gloom about android vulnerabilities I've yet to read about wide scale expoitation. Usually the stories are crap coming from dodgey chinese sites targeting chinese users.

I don't pay close attention most of my tech news comes from el reg. Though I believe if there was serious exploitation going(not involving manually instaling apks or non main stream app stores) on there would be articles here about it.

Every once in a while some security thing comes up that affects a few apps though usually it is yanked from the stores pretty quick.

Android updating won't be fixed in my mind until there is the ability to roll back any upgrade(app or OS) easily. There have been several apps I have updated only to find them worse than before with no way to go back.(I supose one exception is the built in apps. I was able to downgrade samsung S health this way. The newer version didn't support landscape mode and added nothing else that wanted to make me keep it)

no need to worry

System admins etc have a much more secure future than trevor's writing career.

Don't get me wrong we are all fucked eventually (don't care what industry you are in IT or not)

So take the opportunity to have fun while you still can(assuming you can).

Re: what he said

Can't edit posts on mobile. But wanted to clarify position on ZFS. I think it is a good file system but don't believe it makes a foundation for a good storage platform (e.g. 3par replacement)
