Re: Serious biz users don't want Samdung Fandroid or iDrone Crapps
That's useful info, but you'll have to permit me to correct you on a few mistakes you've made here.
Try answering the phone when someone calls you, might do wonders for your business.
I can't see where I said I didn't answer calls (assuming I have a signal on this wonderful phone).
The little numbers that appear on app icons are also there for a reason.
If you have multiple folders (say in Outlook) then the little number only reflects your unread emails in the inbox. Everything else doesn't count. You don't do that? That's probably because you don't get 200+ emails a day.
Briefly hold your finger on the TouchID sensor.
That's useful info, and I've just tried it. But on my BB I can either press the physical mute button (it's neatly placed on the side of the phone, iPhone doesn't have one), press the mute on the mic on the headset I use (iPhone doesn't support this) or press the mute screen button (like the iPhone, but I don't need to unlock it first).
Thanks. Glad to be of service.
Re: Serious biz users don't want Samdung Fandroid or iDrone Crapps
1. An integrated inbox. All your notification stuff -- calls, tweets, emails, notifications -- in one place. Every time I get a ping on the iPhone I have to go hunting for what caused it. The notification center thing is useless for more than one notification, and I shouldn't have to do this clicking on icons searching stuff out. The BB does this.
2. When I'm on a call, don't make me have to unlock the phone to go on and off mute, which takes at least 6 screentaps, is distracting and takes too long. The BB has an external mute/unmute button.
3. The signal strength is way down on my blackberry. I work from home, and there are now places in my home office where there's no signal.
There's more, particularly to do with the standard email app, but I don't want to drone on and on. I've asked my IT department to take it back as it's affecting my productivity. I'm spending too much time trying to work around these issues.
Serious biz users don't want Samdung Fandroid or iDrone Crapps
Yes, I want to use Blackberry. I've been moved to an iPhone, and as a biz tool, it's a complete dud.
I reckon IT departments the world over are run by six year olds that don't have to use what they choose for work either, and they pick the iPhone because it's cool and great at Facetime with the g/b friend or for Facebooking food they just ordered. Mail you say? Didn't try it, and anyhow, who uses that? Yo!
My personal Galaxy has the same issues of usability, but I'm not trying to do anything serious with it, and I wouldn't pick it as a business tool either.
Yes, Blackberry has its issues, and Gawd knows it has singularly failed to stop the bleeding to rival devices, but it's far far better business tool than the polished turd I've been forced to use.
Gimme my Blackberry back.
According to the nice letter the Royal Mail put into the bag that contained a present from my sister, aftershave is considered "restricted goods". The parcel went from Westmisnter to Stanstead, got flown to a sorting office in Belfast(!), was opened (including the card in an envelope), was declared safe, got flown back(!), sent to Edinburgh and arrived with me 2 weeks later with one of these attached; http://www.postoffice.co.uk/sites/default/files/Example-ID8000-Label.pdf
What for? Can anyone enlighten me?
Nice smells though.
"The storage world"? It was just boxes of RAID5 disks.
'The Storage world has learned a major lesson since netapp and that is not to ignore the competition..." Prior to NetApp, "the storage world" was just big boxes of disks banged together with (if you were lucky) a RAID controller. And EMC didn't ignore us; they found it really hard to compete with us.
NetApp made the technologies by which others measure themselves, even EMC. That's a set of technologies that we've used over the years to deliver advantage for our customers. It includes file-based storage systems, storage virtualisation, snapshots, capacity & performance effective RAID, dedupe, thin provisioning, compression and more. And if you reran the tape again, I bet the outcome would be about the same.
I agree with you that Pure are yet another startup that aren't redefining this industry; they're mimicking NetApp technologies. The deck is stacked against them because it's a "me too" business (with added flash). While imitation may be the sincerest form of flattery, it rarely guarantees success.

These sound remarkably like what we already have in a different form factor; CPU/network/storage that looks like a disk drive (or SSD) brick rather than a server brick or a switch brick. Or am I missing something?
I want an impressive set of arguments before I'm convinced this is a flyer; a solid business use case, a good viable technology solution and a workable roadmap and plan. Cheaper, faster and more reliable would help too. I'm not getting any of that from the article.
As I'm in Atlanta for the launch of these, hopefully I'll find out directly what the value/seekret soss/hype is about.
Re: You might as well have just said...
Commodity to you, but useful to me, since I'd never heard of Veblen goods until today.

...with more modern architectures that often target NetApp deployments (ONTAP is more than 15 years old).
Oh dear, so it is. Almost as old as Linux, which appeared in 1991. All those "modern architecture" systems based on a 1991 Linux. Or BSD based systems; BSD is (gasp!) even older!
Yes, I understand that analysts have to say something, especially when they're not sure about the business or the technology or the economic outlook. But it would really help if their opinion was based on a more meaningful analysis. ONTAP 8 is a modern clustered scale out system quite unlike anything else on the market. Mr Blair, please try again.

Re: Benchmark shpenshmark
(It's "cited", not "sited"; using the wrong word doesn't help your argument.)
We do have a flash strategy and a lot more varieties of flash (FlashCache -- big caches made of flash, FlashPools -- mixed pools of SSD and disk, EF540 -- all flash array) than Hitachi has; you just haven't been paying attention.
What we don't have is a recent benchmark with flash SSD, which is a good point.
Wait a doggone minute there...
One correction ; Netapp haven't "given up" on tuning with flash. NetApp was one of the first to employ Flash based caches in 2009 with FlashCache; that's 4 years ago. We still ship and use both caches and SSDs for performance in the latest Ontap 8, along with the all-flash EF540 and the soon to be delivered FlashRay.
It's interesting that you think that the startups you mention all want to be like NetApp when they grow up -- or perhaps that's what they told you? -- for it's certainly what they want you to believe.
The truth is they don't want to be like NetApp. No way. Not in a month of Sundays. That would mean putting in some hard work for the long term, and none of them are in it for the long term.
NetApp has got a whole set of experiences and innovation in this space built over decades of investment and learning that these new guys on the block just don't have. And won't have and don't want either, since their business model (as you note) is a desire to get bought and make the principals some money.
Of course the storage industry is looking at this. Chris, I told you so at SNW in October last year, but you wanted to grill me about the "bump in the wire" cache vendors... Ah well.
For posters here, don't get carried away by memory storage schemes and thinking that it's a solved problem, or even an easy problem to solve. It's not.
For anyone that's interested, here's the background and what's being done; http://snia.org/forums/sssi/nvmp, and in particular, this presentation; https://intel.activeevents.com/sf13/connect/fileDownload/session/461EB56CC073EA43BDFCEC22AE2D3C88/SF13_CLDS009_100.pdf
Next year's tech? Probably not. But it will come; byte addressed, persistent and cheap memory is just too attractive given what we have now. More information can be had by contacting the NVM group at SNIA.
Re: NetApp is 24 NODES vs HDS 4 NODES
I'm not surprised that the HDS box did as well as it did, given that both NetApp benchmarks were submitted in September 2011 (2 years ago) and didn't have the benefit of SSDs. The 6240 is no longer sold.
Re: AAAARGGHHH! They're NOT IOPS!
What do you mean by "file I/Os per second, instead of disk block"?
NFS operations are not "file I/Os" since a large chunk of them -- 72% as I pointed out earlier -- are not operations on the file at all. This sort of sloppy thinking leads to no more than the death of another kitten.
PS; I'm sure all the marketing suits at HDS are really delighted that the rebranding from BlueArc to HUS that they slaved over all these years ago has completely escaped you. Mind you, that's excusable. No kittens died for that mistake.
AAAARGGHHH! They're NOT IOPS!
A little furry kitten dies in the benchmark labs every time someone quotes IOPS on a SPEC SFS.
SPEC SFS does not measure IOPS. SANs do IOPS, and the benchmark for them is SPC-1. NFS systems do NFS operations, and SPEC SFS measures them.
Only 28% of the operations in SPEC SFS are a READ or a WRITE operation (that is, accessing the data). The other 72% of the operations are on meta data (mainly directory information).
There's a big difference. Please, think of the little kitties.
Can't make it, which is a shame. Knieriemen is owe me at least one drink, I'm sure.
I liked the capacity gag above. How about
"I only came here to get HAMRed"
"There's a flasher or two in here tonight"
"No thanks, I'm the nominated drive."
"Run boys, it's a raid..."
Re: Vendor panic
2000 servers with 6 disks each? They're crazy. 2000 servers with 6 disks between them? You're crazy.
Other than that, your story is a good one. For the pub.
<quote>If you just want to dump some data somewhere though, any old cheap storage will do.</quote>
Uh, no. Reality sucks, Mr pPPPP. Bit if you just want to lose your data, any old cheap storage will do.
Correction; Linux O_DIRECT is not Windows Direct I/O
and the Parallel NFS (pNFS) client is still in tech preview; the latter includes support for Microsoft's Direct I/O, which allows for data to be read from disk to application buffers without stopping at file buffers
I've spoken to the Linux developer of the NFS client that's part of the standard distributions, including RHEL6. The support is for Linux O_DIRECT in the pNFS code line, and has nothing to do with Microsoft's Direct I/O. That is a specific Windows OS feature for Windows device drivers.

There's a shedload of work taking place in Windows, and there's a fully fledged open source client available right now; download it from here http://www.citi.umich.edu/projects/nfsv4/windows/readme.html
Re: Server-Side Copy
Unlike FXP it's secure. The client has to inform both the source and target of its security credentials, and that the source will be contacted by a specific target.
What's tiering got to do with it?
Terje Mathisen (a well known programming optimization guru) once said: "All programming is an exercise in caching."
The same applies here. All data management is an exercise in caching.
This isn't about tiering; it's about caching. Unless, of course, you've got a product that does only tiering, in which case it makes a lot of sense to confuse the two.
To clarify my comment;
He pointed out that SolidFire deduplication is global, working across all volumes, whereas "NetApp ASIS only dedupes on a per-volume basis in an array and not across volumes in an array." Alex McDonald from NetApp's office of the CTO confirmed this but said NetApp can have many, many LUNS in a volume.
Since you can have lots of things (LUNs or filesystems) inside a NetApp volume, and a volume is a virtual construct that can be very large indeed -- several 10s of TB -- then global dedupe really doesn't buy you much saved space if you're already deduping across that much data.
Good on SolidFire though to recognize that we're the storage system of choice. ;-)
Alex McDonald of NetApp here.
Chris, my apologies; I promised you some reasoned arguments and background information as to why EMC/Isilon appear to be misunderstanding the specSFS benchmarks. Since you've published, I'm replying here.
Twomey of EMC makes one valid point; "Scale-out means different things to Isilon, [IBM] SONAS, [HP] IBRIX and NetApp." But this isn't about definitions or about what we each mean by scale-out or scale-up or scale-anything; it's about scale -- full stop -- and a benchmark which is tightly defined (and where we spanked EMC). The rest of his arguments are, as usual, diversionary nonsense. What's eating Twomey is the fact that NetApp's submission was smaller, cheaper and faster.
But I am surprised at Peglar, the America's CTO (Chief Technology Officer) of Isilon, because he betrays a serious misunderstanding of the benchmark, and I'm surprised that he isn't better informed. Here's what he should know.
The specSFS benchmark creates 120MB of dataset for every requested NFS operation. You can't control how much space the benchmark is going to use -- in fact, the usual complaint is how big the SFS dataset size is. We (NetApp) chose a volume size of 12TB for each volume giving 288TB. The main number to look at for the benchmark is the file set size created which was 176176GB (176TB) for the 24 node test. We could have created much bigger volumes and could have exported the capacity of the entire system at 777TB. Which would have not made a difference to the results; since the fileset size created would *still* have been 176TB.
Isilon exported all the usable capacity. 864TB. The benchmark dataset size for them was 128889GB (129TB).
So, on inspection, it took Isilon 3,360 10K rpm disk drives (plus 42TB of flash SSDs) to service 129TB of data. NetApp took 1,728 15k rpm disk drives (plus 12TB of flash cache) to service 176TB of data.
Now who's short stroking?
There are two arguments un-informed arguments we hear about benchmarks all the time, and I thought Peglar would have understood them and why they aren't relevant.
Argument 1: If one doesn't touch every byte of the exported capacity then the system is being gamed, so as to short stroke the disks and gain an unfair advantage.
Response 2: There will never be any real world workload that touches *every single byte* of all available capacity. That is not the way systems have, or will ever be used. Benchmarks model a realistic workload and measure systems under that load, not bizarre edge cases.
Argument 2: Creating LUNs that are smaller than the maximum capacity is creating short stroking and an unfair advantage.
Response 2: Modern filesystems no longer couple the data layout with the exported capacity. Thus, there is no performance advantage that is related to LUN size or the exported capacity. As long as the same amount of data is accessed across systems then the equal performance comparison is valid; or, as in the NetApp submission, where a *lot* more data is being accessed, the benchmark demonstrates it's a much better performer. If you are seeing a difference in performance that is coupled to exported capacity, you might want to consider a NetApp system that does not have such an antiquated data layout mechanism.
Summary: The total exported capacity is the combined capacity of the volumes created. It does not have any bearing on the performance obtained.
The argument Peglar makes would seem to indicate that Isilon may have one of those old, steam-driven data layouts. But, of course, an Isilon system doesn't, so why he's making the points he does is beyond me. There are only a couple of reasons that EMC/Isilon could present an invalid premise for an argument; (1) they don't understand the subject material, and lack experience in debating these issues, or (2) they fully understand the subject material and believe that the person they are trying to convince does not.
I'll let you guess as to which I think is the case.

HP can't fix this; they sealed their fate years ago...
when they forgot to make any continuing investments in storage in the mid 2000s.
Then Dell-the-server-company bought EqualLogic, and HP-the-server-company woke up with a start & bought LeftHand (now the P4000), lurched sideways and bought Ibrix (X9000), and thought that they'd fixed the storage problem that was the EVA.
Wrong choice. The P4000 is small beer, a sort of one-shot technology that was OK when they bought it, but it's not going anywhere, doesn't scale well and isn't that popular as it's iSCSI only (the EVA is FC). The X9000 NAS boxen were never going to set the world alight; Ibrix and their dismal sales record proved that already. That's what you get for buying companies on the cheap.
So HP dig deep into their trouser pockets and buy 3Par, and discover the fit isn't that splendid; the EVA's natural market was at the channel low-end where bundles of storage, servers and networking make sense. 3Par doesn't fit in that sales model; it's a different beast than the EVA.
Data growth & management of the increasing amounts people want to store has illuminated the EVA in the worst possible way; it sucks as a platform for tomorrow, and it's barely adequate for today. 3Par might be the route forward for today, but it's asking a lot of EVA customers to do a rip-and-replace to make the switch, especially as they've already invested and need a return on that money. (Interestingly, 3Par is equally crippled for the long term; no dedupe, no compression, not unified storage, and unlikely to get these essentials any time soon. Thin provisioning is the big claim to fame, along with performance in a straight line. That's it.)
No HP storage visualisation appliance to ease that pain either, since the SVSP has been unceremoniously dumped.
Rock and hard place. Channel partners must be wondering what HP will do next, since they're facing some seriously stiff competition from particularly NetApp, with whom they're equal 2nd according to IDC.
