Try Windows 95 beta on an AMD 386 40Mhz with 4MB of memory.
My first introduction to the Win9x stack.
Or installing WIndows NT 3.5 Workstation from Floppys and finding a corrupted disk (36 of 38 from memory)
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.
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.
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.

There you go, problem solved :)
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.
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.
Umm Windows NT 3.5 Workstation, Windows NT 3.51 Workstation, Windows NT 4.0 Workstation and Windows 2000 Professional would like to talk to you behind the bike shed :)
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.
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.
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.)
Can run both natively on partitions of the hardware.
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 :(
Also driving the low price is last time I checked about 80-90% of traffic never leaves the nation.
Compare that to NZ where I live and approx. 60% of traffic is international.
SMB Array - EMC has VNXe
HP has a similar capability to VPLEX in Peer Persistence on the 3Par platform although less flexible and more feature limited, however a good match for VPLEX Metro when used with VMware or Hyper-V
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.
Purple are surveillance drives with firmware optimised for multistream writes.
So you want to make it BIGGER?
See what happens when you compress a 15GB MPEG-4 HD video file.
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.
VNX can use flash as both Cache and a Data Tier at the same time.
Not looked at Nimble enough to know what it can do TBH.
Not sure about the UK but even down here in NZ 20Mbps national is not that hard to acquire.
Any DOCSIS3, VDSL2 or Fiber connection should suffice.
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.
Funny most of my V7000 boxen are sitting in traditional HP sites.
I am running a Iomega IX2-200D with 2 x 2TB disks. (Free at an industry event or would have been Synology 4 Bay)
Plex Server running on my gaming PC sharing the content.
Currently using the Plex App on the Samsung 2013 Series 5 TV (UA50F5500AM) but the Samsung WiFi implementation is a PITA so looking at mounting an Intel NUC (i3, 4GB, SSD) on the back via the VESA mount and running Windows 7 + Plex Client and having another Windows client available with a real keyboard and some big screen gaming (Intel HD graphics will be fine for what I play)
You mean the same system HP have used in EVA and now 3Par for years?
Except that if you issued a PxE boot message to 1000 desktops they would be booted in 30-60 seconds from a SATA magnetic disk and 10-20 seconds from low cost consumer SSD's.
IBM's storage strategy in the entry/mid-range is Storwize and Storwize. :)
They do modular in XIV but no real virtual SAN offering at the moment.
There have always been 2 GT releases per platform (GT and GT2 on PS1, GT3 and GT4 on PS2 and now GT5 and GT6 on PS3)
As for the AI cars they have pissed me off since GT1, making no allowance for player cars at all.
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.
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.
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>.
The others that you forgot to mention are vBlocks from VCE and Flexpods from NetApp/Cisco/VMware.
Will be interesting to see what Oracle are doing for storage, will it use a ZFS based system, a Nutanix like system or Pillar Axiom type tech?
The SSD provides up to 98,000/90,000 random read/write IOPS and 540MB/sec sequentially reading, 520MB/sec sequentially writing. These numbers vary with product capacity.
While Active Directory is not the best LDAP implementation it DOES have the largest installed base by a long margin.
There are a LOT of admins out there with AD skills and CxO's are comfortable with the technology.
Betting against Microsoft tends to be a bad idea in everything but game consoles.
Looks like an Electric Delta Wing
Comparing an all SSD config to a disk based one is a little off.
How would an 8 Node all SSD config of Isilon S400's go I wonder?
Serious question here, how long since you have used an up to date version of Windows?
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.
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).
Of that list the "At Risk" products are:
DS3500 (V3700/V7000 is the replacement)
DS5000 (V7000 is a natural replacement here)
N Series (V7000U and SONAS will replace)
Safe products should be:
SVC (Although I would expect a V10000 ish system with 8/10 Core CPU's and 240/480 12gbps SAS Disks + Clustering to replace it eventually)
Tape (TS3500 stays for Mainframe, TS-1140 and LTO-6 is not a problem if tape stays and IBM have a reasonable OEM business in selling bare tape drives)
ProtectTIER (Someone needs to take on EMC/Data Domain and HP is not getting it done)
SONAS (Needed to replace big NetApp boxen from a CIFS/NFS perspective, maybe a "Gateway" that can attach to XIV/SVC/DS8000 as a future SONAS offering ala VNX VG2/VG8 Gateways)
My $0.10 (Inflation is a bitch)
VNX has some life left but I can forsee a world with 3-4 levels of VMAX and Isilon Nodes and/or gateways on a common hardware platform using scale out rather than scale up.
Yes because owning a gun is proof that you are going to attempt an armed robbery.
Idiots from RIANZ need to get a clue.
I think there is a lot of people on here making a false assumption.
That assumption is that the de-duplication feature is designed to save Mega storage resources.
From my point of view it is obvious that the de-dupe is for user benefit, when dealing with 50GB or 500GB of data there is a good chance that you will upload a duplicate file, even more so if you are using it for offsite backups. The de-dupe is to save you the transfer and storage budget of using Mega so that you can script backups and only changed files will be re-uploaded or you can upload your photos directory again and again and not duplicate the data.
It is to drive ease of use for the customers NOT to save the Mega storage nodes on capacity.
So how do you provide the decryption key for user #2 for a file that is encrypted by user #1 if you do not have the private key?
A little sense here please.
How are mega.co.nz going to de-duplicate encrypted content?
The very act of encrypting the data makes it unique, or should if done correctly. Only if you tried to upload the same content, encrypted with the same key, twice should this kick in. So you upload a folder with a heap of photos in a single operation then it will de-duplicate that data. However if two people upload the same media file (Non-copyright of course) then as far as the service is concerned that will be two unique chunks of binary data, they have to be if encrypted with different keys.
Cisco should buy Nutanix and develop that platform for both VMware and Hyper-V.
Unless you play games in which case the iMac's nVidia GT640M to GTX680M are a MUCH better option than the Intel 4000 on the Mini
X1000, X3000 and x5000 become StoreEasy with the move to Windows Server 2012.
Xx000 (WSS 2008 R2) -> StoreEasy (WSS 2012)
P4000 G2 (3.5" Disks and SanIQ 10) -> StoreVirtual (2.5" Disks and SanIQ 10.x)
