Lost little X-IO lays off ~75 staff in Colorado as it shutters factory

Michael Duke

It is interesting that datacore was always pitched as the virtualisation engine to use, I always thought it was a better match to IBM's SVC/StorWize platform.

With its per enclosure licensing it was quite a cost effective option.

Quad-core coffee table trumped by dual-Mac garden furniture

Michael Duke

I was expecting a Windows ME disc not NT Workstation.

There was nothing wrong with NT at the time, it was a good desktop OS. Rather lacking in server chops back then and well behind the competition in features but a reasonably competent desktop OS for the period.

Computer says: Stop using MacWrite II, human!

Michael Duke

I had a war going on with one of my customers for about 8 months back in 1996.

They were a high school and they insisted that they needed 2 "Multimedia" machines in the library with CD-ROM's and Soundblaster cards. Running Windows 3.11 with apps like the Microsoft Encarta and its ilk. The rest of the customers network ran on a NetWare environment with BootPROM equipped PC's running Win 3.11 off of the network with locked down and well managed.but we could not use that for the library for a variety of reasons.

It got to the point where I was replacing all of the Windows/DOS configuration files on NetWare login via login script to stop the kids installing games under Windows or DOS and having a "Shutdown" button that removed key Windows and DOS system files on Windows exit so that they could not use the machine outside of the controlled Windows environment.

Worked well but was quite time consuming to install new apps.

HPE targets Nutanix, squeezes into hyperconvergence suit

Michael Duke

Re: VxRail is based on Dell Power edge servers

A few points.

1. VXrail is available today and it is NOT on Dell hardware.

2. The Dell/EMC deal, while being on track, has NOT yet closed and there is no hardware partnership between EMC and Dell at this point in time.

3. I am not 100% sure which ODM is being used for the VXrail kit but it will PROBABLY be Quanta who are the ODM for the VXRack and ScaleIO nodes.

Two flashy VMAX bridesmaids bare ankles at EMC's DSSD groom

Michael Duke

Re: funny

Once you hit 8 controllers,4+PB of raw capacity , 16TB of memory, 384 CPU Cores and 256 16Gbps front end ports do you really need more scale in a single system?

There comes a time where the complexity of the scaling is more than it is worth.

If you need monster scaling then look at a solution like ScaleIO, Isilon or ECS depending on the data type.

VMware VSAN … and the great missed opportunity

Michael Duke

Re: Fiendishly expensive

Yep I agree with you on a 2 controller SAN vs. Scale Out maintenance risks.

However on a dual controller array a firmware upgrade cycle is on the order of 12 months on average, assuming a tier 1 vendor with a mature product. If we look at an NDU on a EMC VNX for instance total exposure is 2 x 30 minute windows every 12 months (one per controller).

vSphere 5.5 had 15 patch release cycles in 25 months, an average of every 1.6 months. Assuming your 3 hosts and an average of 30 minutes to evacuate the VM's, apply the patches, reboot (if required) and re-enter the cluster we are talking 7-8 x 90 minute windows in those same 12 months.

Not quite the same risk profile.

As for any scale out solution has the same limits I agree and with the ScaleIO solution you get that 4th host for the cost of the hardware and hypervisor license, no per processor costs, just license the space you consume. In little old NZ that equates to between $15-20K in savings depending on support level.

Re: Fiendishly expensive

Duncan I have a lot of respect for you but here you are being disingenuous at best.

Look at the first paragraph on Cormac's design guide that is on the VSAN product page....

The minimum configuration required for Virtual SAN is 3 ESXi hosts. However, this

smallest environment has important restrictions. In Virtual SAN, if there is a failure,

an attempt is made to rebuild any virtual machine components from the failed

device or host on the remaining cluster. In a 3-node cluster, if one node fails, there is

nowhere to rebuild the failed components. The same principle holds for a host that

is placed in maintenance mode. One of the maintenance mode options is to evacuate

all the data from the host. However this will only be possible if there are 4 or more

nodes in the cluster, and the cluster has enough spare capacity.

Where VSAN doesn't shine: Sources explain EMC's ScaleIO purpose

Michael Duke

3 Node VSAN clusters, while supported do not have any resilience for node maintenance. How are you going to patch your 3 node vSphere cluster running VSAN when you cannot put on into maintainence mode. Also 2 node will only support branch offices and needs an external (vCloud Air) failover manager, no thanks.

My top three IT SNAFUs - and how I fixed them

Michael Duke

Best one was a Netware 3.12 customer, their server had two network cards in it to support the two network runs around the office on Thin Net, each about 150m ish in length.

Get a support call one day that the clients keep dropping so I grabbed our network kit (BNC tester, 2 spare NE2000 cards, 3 spare terminators, a few T's and a couple of 5M lengths of thin net) and head out to the customers site.

Upon arriving I notice that the server has moved to the other side of the office, and both segments are connected to ONE card.

I ask why this is the case and they admitted to losing one of the terminators when moving the server and of course they did not see the issue, I measured the network before I fixed it and sure enough, total length 327M :)

Re-terminated the second card, split the segments and of course the network issues disappear immediately.

Easiest emergency callout fee we ever earned.

Welcome, stranger: Inside Microsoft's command line shell

Michael Duke

Quote: Windows XP was the first PC operating system to drop the MS-DOS Prompt and change it to Command Prompt, due to a change to the NT kernel. The Windows NT family has used the newer Command Prompt since it started with Windows NT 3.1, so it was nothing new on that side of the fence.

The content business wants Netflix out of Australia

Michael Duke

Re: Sony/Netflix contract

Exactly. Look at the local launch of NetFlix in NZ. Something like 1500 items in the library compared to the nearly 9000 in the US service and we are being charged a 30% premium for access to that reduced library.

Sky's Neon service is even more expensive at $20NZD a month and Spark's Lightbox is the same price as NetFlix @ $12.99NZD a month (Well actually 30 days).

So to get the same coverage as NetFlix and Hulu Plus in New Zealand I need to spend $46NZD a month and get maybe 4000 items in the library. In the US $22NZD gets you access to NetFlix and Hulu Plus with a combined library of ~19,000 items.

And the content providers wonder why Aus/NZ is a hotbed of torrents and stolen content.

Storage BLOG-OFF: HP's Johnson squares up to EMC's Chad Sakac

Michael Duke

The same can be said for Johnson. Chads point is that a true AFA is not the same as a 3Par 7450 or XP7 with pure flash. There is a measurable latency difference between most of the current startup/ex-startup AFA's and a hybrid array that is not hybrid.

Even HP's tools model approx 1.5MS of latency in an AFA 7450 with the MLC / cMLC disks.

Compare that to 500us for Xtreme-IO / Violin etc. A 3x improvement in latency is significant.

Re: Only EMC's View

Except that HP 3Par and HDS HUSVM are NOT AFA's.

They are hybrid arrays without disk, there are significant differences in latency between a hybrid box with just SSD (VNX/3Par/V7000/HUSVM) and a true AFA (Xtreme-IO / IBM Flash System / Pure etc.)

NetWare sales revive in China thanks to that man Snowden

Michael Duke

As a 20+ year IT veteran who supported NetWare from 2.15c up to v6 including Groupwise 4.1 -> 5.5 migrations and 5.5 -> 6.0 as well I really enjoyed the stability and performance of NetWare against Winblows.

I had NetWare 3.12 servers with 400+ days of up time, try that on NT 3.1/3.51, it just did not happen.

Compare Windows 2000 AD to NDS on NetWare 5.1 and there was NO comparison, NDS was so far ahead MS needed a telescope to see it.

But marketing and ownership of the desktop triumphed over a superior product and here we are today with MS still not caught up in some areas, there are still limits to how you design an AD for 20K users when NetWare and NDS was just getting out of second gear with 20K users.

Unfortunately I see a lot of similarities between Novell and VMware :(

Titan falls! Blizzard cancels World of Warcraft successor

OK so you quit 5 years ago, now there is an easy way to solve that, cross realm LFD has fixed your issue, I leveled a Paladin from 10-50 in dungeons via LFD almost exclusively in a few short days (I do not get long play sessions).

Blizzard do work to solve issues as they arise, they may not fix them in a few days or weeks but they DO get solved, or at least worked on.

I do not get the hateorade on this, I really do not.

So they spent a bunch of time and money and are not happy with the result. They could do 3 things.

1. Keep pouring time and money into a dog with fleas (See Duke Nukem Forever for the outcome of this)

2. Polish the turd a bit and release it with much hype and never fix the problems (The EA option)

3. Call it off, junk the work and say "What's Next"

The third option requires a large amount of discipline and guts, no shareholder will be happy with that approach but it is about quality in the end of the day.

I respect Blizzard immensely and I say good on them.

Re: Nobody has yet asked the important question

10's of TB is a VERY low estimate.

I would put it in the Petabyte range at least.

A quick look at "Recent Releases" on one of the DVD sites lists 1,081 movies released in the last 90 days. At a VERY conservative 15GB per movie average that is 15.8TB in 90 days or approx 65TB a year which is, if we say the industry has done HD for 4 years, a quarter of a PB right there. Add historical digitised content going back 20+ years and amateur/Cam Girl/Red Tube type content and I would say far side of a PB easy.

Atlantis hopes to sink fangs into EMC's ViPR with boosting product

Michael Duke

They cannot even get the comparison configuration right.

VSAN disk groups are 1 SSD device and up to 7 magnetic devices. Up to 5 groups in a host. To support 24 x 1.2TB Magnetic disks would required 4 disk groups and therefore 4 SSD devices. You cannot chop up the FusionIO card into 4 LUN's and stay supported and you cannot at this time use external disk shelves.

If they cant get the before right I am not sure I trust their analysis.

EMC's flashy XtremIO? I Xpect it will be great... in a few years

Michael Duke

XtremeIO is a tool in EMC's kit bag, strategically not as an individual offering (Not that they will turn down sales I am sure, but even EMC are pitching it at big VDI right now) but as part of a complete "Big Picture" play with ViPR providing the "Software Defined Storage" control layer with XtremeIO, VMAX, VNX, Isilon, ScaleIO and Data Domain as storage resources to be managed and VPLEX/RecoverPoint providing the availability piece.

It is an impressive story that really only IBM can compete with, but even IBM have some work to do in this space.

Delta Air Lines makes mass Windows Phone 8, Lumia 820 buy

Re: And the flight entertainment system...

Really?

The entertainment system in the Air New Zealand 777 I flew to SFO in 2010 ran Windows CE on the endpoints and my take is that these things do not change so fast.

I know this because I had to wait 30 mins while my screen rebooted loading the WInCE image over a serial connection.

Newer systems are probably Linux based I agree but the vast bulk of the install base is probably still Windows powered.

Is that a flash stick in your pocket, VMware, or are you pleased to see us?

Michael Duke
Thumb Up

EMC buying ScaleIO will pave the way for VMware to have a storage hyper-visor that is worth deploying.

As with ViPR it makes sense to have the storage company develop the storage tech and then transfer it to VMware rather than transferring the engineers to VMware.

I think ViPR, or a subset of, will end up at VMware. But EMC will keep a version of it in their camp as a hedge against Microsoft/OpenStack/<Insert next big thing in server virtualisation>.

CFO warns IBM's 'underperforming' storage crew: We'll take 'substantial action'

Yes StoreVirtual is the new gen8 servers running V10 of the LeftHand software.

StoreEasy is the NAS range, running Windows Storage Server 2012 and or IBRIX depending on model.

StoreOnce is the D2D re-brand.

P9500 is HP's mainframe offering BUT they have single digits of the mainframe storage market, IBM and EMC have like 80+% between them and the Hitachi vendors (HDS, HP and formerly Sun) have the rest.

it is no surprise that HP do not want to engineer FICON into the P10000/V Class.

Michael Duke

Matt, The Mainframe business is low revenue but high margin business and you will pry it out of IBM's cold dead hands. It is a no brainer for them to keep pushing as they have 80+% market share and a captive audience as the path to move off a mainframe takes YEARS.

Erik, Yes the whole DS, DCS and N Series range are OEM'ed from NetApp/LSI and that is why they will go, the StorWize range is resigned to replace them, the new V3700 is the box to replace the DS3500 as the V7000 replaced the DS3950/DS5020 and the DS5100/5300 ranges. The only product from that line that might survive the end of the year is the dense DCS3700 for Video etc.

IBM will get rid of as many OEM'ed systems as they can, they want to own their storage destiny and they have either acquired the products to do it (XIV, TMS) or built them in house (StorWize, SONAS).

HP are doing the same thing of out with the old (EVA, P2000/MSA2K, P9500/XP) and in with the new (StoreServ 7000/3Par, StoreVirtual, StorEasy).
