Don’t get in a cluster fluster, Wikibon tells NetApp users


TCO = Totally Contrived Opinion?

Say it ain't so Chris - the TCO argument in this article is totally contrived. So many errors, so little time:

1) Cost of 16 month cutover from 7-mode to C-mode system ($622,000). Really? 16 months for one storage system? In my experience 1 month would be more than enough time.

2) Cost of planning, upgrading skills, and testing ($275,000). Unique to C-mode? Nope - upgrading to any new storage platform, even ZFS, would incur this cost.

3) Additional cost benefit of C-Mode Migration: How about nondisruptive operation? Zero planned downtime? Seamless scale out and scale up? Access to a universal data fabric? Multi-cloud data mobility? Hmm, there must be some $$ value there too.

IMO you can take at least $1M from the Wikibon 6-year C-Mode costs and show a payback of 12-24 months. Anyone that wants to do a more realistic TCO analysis - ask your Rep or SE to run a TCO report @ www.netapprealize.com.



DataCore’s benchmarks for SANsymphony-V hit a record high note


Apples and Oranges

Agree with AC, this is a dubious comparison. Any reasonable enterprise server with a dozen SSDs and loaded up with DRAM will show "amazing" SPC-1 numbers. As I recall, SPC was created primarily to make a realistic comparison of performance metrics between enterprise storage arrays that could scale out to hundreds of TBs.

Too Many Storage Array Lines?

"Dell/EMC will lose some storage array lines and meet fresh problems on their way to the merging"

Michael: "Joe I think we have too many data storage lines, I just counted 16 of them."

Joe: "What? Sorry I can't hear you, the top is down on my Ferrari. I'll have to get back to you."

Solving the data silo problem using a crawl-walk-run strategy


What problem are we solving again?

If your problem is inefficient data silos, you are in serious need of a refresh. Over the past 5-10 years all the major storage vendors have offered virtualized storage pools that seamlessly move data between arrays and tiers. If your problem is lack of ability to set policies and QoS limits, call your local storage vendor and chances are they have a solution for that too (NetApp does). As far as I can tell from the Tech Field Day video (link below), 1) there are quite a few technical concerns from the experts around the table and 2) DataSphere only supports two storage OS's - NetApp's ONTAP and Isilon's OneFS. Doesn't seem all that compelling unless I am missing something here.




Flashy upstarts facing IPO pressure. Get on with it then


HDS and Oracle are the remaining 'tier one' storage vendors that still do not have true AFA products, I'd keep an eye on them as acquirers. Otherwise, wouldn't be surprised to see the smaller flash players merge as they run out of cash and need to consolidate operating costs.

my 2 cents,


EMC learns object lesson in accuracy after ViPR death goof


Clear as Mud

This is the most confusing clarification since #DeflateGate.

ViPR Controller 2.2 does not support ViPR Data Services components...But to use ViPR Data Services on file arrays, you must be running ViPR Controller version 2.1.x, with a ViPR Data Services package.

Kryder's law craps out: Race to uber-cheap storage is voer


The HDD in your mirror is much larger than it appears

"To reach 20TB by 2020, the 500GB/platter drives will have to increase areal density 44 times in six years. It isn't going to happen."

Huh? to reach 20TB by 2020, areal density would need to double a little more than 5 times in the next 6 years. (.5TB / 1TB / 2TB / 4TB / 8TB /16TB), not 44 times. All right, this is not gonna happen either.

More likely that we'll 4 or 5 platter (or maybe 6 platter) 3.5" HDD's at 40TB by 2020, which only requires 2 generations of capacity doubling, as vendors put the HAMR down.

Violin's arrays play in Concerto - but they can't hit the dedupe notes yet



I don't see anything on Violin's website that indicates the 7000 is a front-end cluster controller for 6200 arrays. Its simply shown as a dual-controller box with up to 4 storage shelves and up to 280TB. Is this some top secret project thats now not-so-secret?


NetApp gives its FAS range a 4 MILLION IOPS dose of spit'n'polish


Post processing dedupe has its advantages

Post-process dedupe has a lot going for it, number one being that it doesn't get in the way of a CPU thats busy with server I/O requests. Number two - since you have more time to process hashes you can add data integrity checks to avoid hash collisions all together. And...if you schedule a dedupe run each night, the capacity overhead required is surprisingly small.

Re: Software

Agree with TheVogon - what would you replace RAID-DP with? Data Dispersal and Erasure Coding have their problems too. Nice thing about NetApp is that as soon as a drive hiccups, its data is automatically copied to a spare drive - avoiding any RAID rebuild time at all. Most drives die slowly, not suddenly. If your software is smart enough to detect this, you can use it to your advantage.


The future of storage is a horror show - just ignore the biz strategists


Everything is more complex Chris

Interesting perspective, but why pick storage as the complexity poster child? I remember when I could adjust the valves and points on my '63 VW bug, Then along came electronic ignition, fuel injection, and onboard computers. I didn't ask for any of those things and I surely can't work on my car anymore but I must admit despite this complexity cars seem to run a lot better and last a whole lot longer than they used to.

Yes storage was easy back when you had some bus & tag cables connected to a few disks on an IBM 360, but as I recall you were maxed out at 32 drives, or about 10GB. Then along came MS Office, Oracle, and oh yeah the interent and suddenly everything got more complicated.

Not sure I'd call it a horror show but its true storage complexity is part of keeping up with the pace of data growth and diversity, whether its in your data center or somebody else's in the cloud. So just as you need a good mechanic with sophisticated diagnostics to work on your car, you'll need a good IT storage architect to sort through all the options and design a proper data storage network.


The numbers are in: EMC still ruling storage LIKE A BOSS


Fiscal vs Calendar explains it

NetApp's fiscal Q1 falls in Calendar Q2, so its natural to see a drop from FYQ4/Q1 i.e. CYQ1/Q2 - I can only remember one CYQ1/Q2 sequential gain in the 7 years I've been here. But hey how about NetApp's 8.6% year-over-year growth, and the fact that EMC and NetApp are the only ones growing in tough storage market!


Flash cheaper than disk? 'Customers aren't buying that', says NetApp CEO



At last check, an 800GB SSD (3 watts) actually consumed more power, cooling and rack space per GB than a 4TB HDD (7.8 watts).


Imation snaps up Nexsan for $120m


Nexsan is not "one of the myriad storage statups", but rather found itself competing with a myriad of startups. Might explain why Imation got them on the cheap.

What's the way ahead for Dell storage?


Re: History is a great teacher

2-3X margins for making vs OEM'ing? Really? If that were the case, Dell would be making their own tape drives, routers, keyboards, desks and staplers. Simply not true. Dell would have given Equallogic global reach with or without buying them. Darren Thomas tried his best but unfortunately leaves a legacy of buying expensive storage companies that contribute continual declining revenue for Dell.


Re: History is a great teacher

Did they need to buy Equallogic to get that run rate? Me thinks not.



History is a great teacher

Dell's storage division seemed to go into cardiac arrest the day they announced their split from EMC. The patient doesn't seem to be doing much better today. How would I fix it? Absolve all those aquisitions and go back to OEM'ing best-of-breed products. Dell's roots of greatness are in vendor negotiation and suppy-chain distribution. Shouldn't they stick to what they do best?

EMC: 'Nope', XtremIO won't link to back-end arrays


The market doesn't want unified storage? Really?

Got a chuck(le) out of the comment "we would end up with something similar to NetApp, and the market doesn't want that." Um, Chuck might want to take a look at the calendar, its nearly 2013 and apparently customers do want universal storage that's agile and unified.
