The bigger these claims of capacity savings become, the more the scope for a significant mis-sizing! As we all know, 'your mileage will vary' so the bigger that claim, the bigger the margin for error! Given the skepticism that even still exists in some corners around technologies like thin provisioning, I can imagine many IT shops having significant concerns over sizing, especially when close to the upper limit for these relatively small AFAs.
Why do we need to have a distinction for SSA vs arrays that can have HDDs installed in them. People don't buy a SSA because it is a SSA, they are looking for an array with certain performance characteristics and in the current market that is most likely to be met using SSDs but not necessarily just SSDs. Gartner talk about the ability to put HDD in the same array as SSD as if it is a bad thing. Surely flexibility can only be a good thing? If you can deliver the required performance without having to go for a completely separate silo of storage then why wouldn't you?
Re: Is there a comparison between the different flash vendor offerings?
Joking aside, with dedupe 3PAR now looks the real deal. One of the most scalable flash offerings, very very quick (certainly on a par with all but the most rapid of AFAs), fully functional, 6 x 9's, and flexible in that can have hybrid options as well. Very few companies will have just flash arrays (for some time) so if you are going to have a mixture of flash, hybrid and disk arrays, then 3PAR avoids the need for separate silos.
Re: why are you including Tegile
At $2/GB, you could argue that 3PAR is in the commodity space too. For a fully functional array, delivering 6 x 9's availability, to be in that price bracket is impressive!
Re: Is it yellow or orange?
Too keen with enter key... Offering 6 x 9's availability and a lower price per GB. Why go for a niche product when you don't have to any more.
Re: Is it yellow or orange?
This sounds more scalable and more functional than Pure so looks like the similarity ends at the pitch. HP do have their flash strategy bang on. Why have a flash silo when you can have a tier 1 array, offer
Re: Why AFAs are small
If you're spending money on an AFA then you do so for a reason and you want to thrash it ... so it would concern me that doing just that could cause problems!
And in terms of why they are so small, your second point is irrelevant as you're first point says that they can't currently scale due to technical limitations.
And as for your second comment, the AFA's are saying that flash is cheaper than disk so why should that only apply to smaller requirements? If it's cheaper, it's cheaper ... surely economies of scale only enhance that for bigger arrays? What you're also saying is that hybrid arrays are the way forward ... flash where it is needed, spinny stuff when it is needed.
So in defending Pure what you've actually said is that its' architecture won't scale, and flash is actually more expensive than disk despite their claims.
And whilst I'm at it ... what is an 'AFA customer'? There is no such thing. Find me any customer that doesn't have a variety of performance requirements across their environment. There is no such thing as an AFA customer. There are customers who have a performance requirement for some of their data sets but those same customers will have cold data sets so are they a 'spinny disk customer' too?
Pure switch off inline dedupe when the box gets busy. And why are all these afa's so small? I know they claim usable capacity as being after dedupe but even then they top out about 100tb. Why not just make a bigger one. Makes you think that there is some sort of scalability issue they are gradually working out.
Re: Thinking outloud $/GB coupled with Pooled vs. Persistent VDI Desktops
Have a look at a 3par 7x00. Afa now if that's what you want but flexible moving forward too. And well under the $/GB numbers talked about here.
Everyone has that problem though so don't try and make out IBM are suffering more than the rest. The fact is that customers are moving more to a 'good enough' approach and midrange arrays are way more capable than before. Everyone needs to sell a lot more than they used to to get to the same $ amount. Yet IBM seem to be doing a much worse job of that than most of the other vendors. Everyone is shifting more capacity than they used to so that defence is weak!
IBM storage is dead! The numbers are tanking and without a server biz, they have nothing to attach to (historically their main strength - very very few people have IBM storage without having IBM servers - I sold IBM storage for years and it is almost exclusively to 'house' accounts). The features that are mentioned in the article are them just trying to catch up with the competition and the absence of dedupe, and fairly mediocre performance mean that they are struggling to stand out! Dell and Netapp are waning too, HP 3PAR and EMC VNX2 are the only 'traditional' arrays that are still growing and the rest of the interest in the market is towards AFA's, hybrids and SDS.
The F400 is a 5 year old, now obsolete, array using no SSD or flash and still beats this latest greatest array from NetApp. Really? If you were NetApp, you wouldn't even publish this! And surprised how poor the V7000 is without SSD.
Couple of IBMers really feeling the need to get all defensive! So storage software like DS8000 array licenses, etc, are already rolled into the storage number so don't try to suggest that their storage numbers are underrepresented. IBM has had too fragmented a product line for too long. Yes, most vendors have multiple products, but there has been more overlap and confusion with the IBM portfolio than most others. The nSeries, DS5000, SVC/V7000, XIV and sometimes even the DS8000 have all been sold into the same space at times. IBM seems to have phases where one product is the answer, what is the question. It's been XIV but they seem quiet on that one now, with V7000 being the current trend. But regardless of how sound your logic is about a breakeven hardware business being worth being in because of the traction it provides for more profitable business lines, IBM isn't interested in hardware. I worked as a hardware salesman for IBM for over a decade and always felt that hardware was of no strategic importance to the company. Most of the xSeries guys have gone to Oracle, most of the storage guys have gone to HP, and important as Power is, it is a declining market too.
Poor analogies aside, the truth is that EMC is built on an aging and inflexible architecture and is struggling to keep up with the functionality and performance being offered by more modern architectures, of which 3PAR is one of many! And the point about the fork lift upgrade is not that moving to 3PAR isn't a forklift upgrade, but that if your upgrade is as complicated whether you stay with EMC or move to another vendor, then now could be a good time to move to another vendor.
I'm pretty sure most vendors (I work for HP, worked for IBM) will only provide free firmware updates for storage arrays as long as you have a support agreement in place. I didn't realise that HP ever provided firmware for unsupported arrays anyway. I don't think it is unreasonable to expect a valid support contract to be in place to receive enhancements to existing code.
Re: Now serving -- fast data with data reduction only.
Considering they claim 6:1 for average environments giving $3-6 per GB but as low as $2 per GB for VM then your 8.8:1 for VM puts their figures in doubt!!
It's not really saying anything that people don't already know ... StoreServ is the 'best' midrange array. And the reason is that it's an enterprise array masquerading as a midrange array, at midrange pricing. All the other arrays listed are classically midrange.
Even IBM don't seem to be pushing XIV that hard these days, they are all V7000 at the moment. It does change all the time though so maybe XIV will be flavour of the month again soon,.
Seriously Eric, are you for real? HP has a much simpler portfolio than EMC. EVA and VTL (I guess you mean VLS) have both already gone end of life so HP have a single dedupe solution in StoreOnce ... EMC have Data Domain and Avamar. P4500 is an iSCSI only solution. In terms of block storage, if it's very low cost it's MSA, if it's 6 x 9's it's P9500, but everything else (95% of use cases) is 3PAR. So from 8 drives, to nearly 2000 drives, from SSD to Nearline, it's all 3PAR. EMC has VMAX, VNX and XtremeIO all covering that space and no interoperability.
HP and NetApp have a much more similar model. Buy into the benefits of 3PAR / NetApp and then just pick your size. You don't need to worry if you're small or huge, you have access to all the same functionality.
Re: Gave up tape and removable storage years ago
How many years have we been hearing that 'tape is dead' yet it's still going relatively strong. All these newer, faster tiers don't replace anything, they just give more choice and flexibility. There will be storage scenarios that need tape, there will be storage scenarios that need decent performance and decent capacity, and there will be storage requirements that just need blistering fast. And most people have all 3, and more. Flash doesn't replace disk or tape as such, it just means that for apps that might have needed huge numbers of spindles and wasted a shed load of capacity as a result, there is now a better way! The clever vendors are the ones who will offer all these choices as seamlessly as possible. The HP approach of having one enterprise featured array that can offer pure flash, hybrid, and SAS is a good one. The same addressable market for EMC is covered by about 5 different arrays! Same for most vendors, to be honest.
Re: Sales dropping the ball at HP?
Frank, I've tried finding you on LinkedIn but to no avail. If you are still in the market for the capacity then maybe the admin of the site could exchange our details? I do agree with the other poster who replied saying that putting 3PAR behind SVC is diluting the benefits of 3PAR, but the 7000 range is very cost effective so you could still see a benefit in going with 3PAR. The new MSA's will absolutely fly so they could be an option if supported.
So the quote says they have most of their success against NetApp, EMC and Dell, yet HP are the ones you mention in the title? Axe to grind?
Re: Storm clouds
Rewards how? It would mean they have to buy in the hardware components for their XIV, V7000 and probably some other storage platforms, or develop proprietary platforms for them which increases cost and slows down development. And also a hell of a lot of commodity servers still get bought, and it's a lot easier to attach storage to a server sale than it is to compete with someone who is!
Re: Storm clouds
Although the x86 market isn't an overly profitable one at the moment, there are other benefits for the likes of Dell and HP in remaining in it, less for for IBM which has already ditched personal systems. The buying power and economies of scale help prop up other platforms, like personal systems and storage. Many of the storage solutions on the marketplace are increasingly based on x86 server platforms, and maintaining control of design and manufacture of that is useful. Also, there is a lot to be said for the market presence and penetration that servers get you. I'd wager that HP and Dell sell a hell of a lot of other 'stuff' on the back of commodity server sales. I'm not being critical of IBM's strategy as I think it is also a valid one - the less valid approach is a half way approach where all benefits from either strategy are diluted so for IBM to increasingly get out of commodity markets is another move in the right direction.
As you correctly mention at the start of your post, you have no knowledge or understanding of 3PAR. 3PAR doesn't use traditional RAID sets either, widestriping all day across all drives in the array, so the management issue you raise isn't really a point. It also allows many 3PAR customers to drive extremely high levels of utlisation, greater than 90% in some cases. Compare that to the huge amount of wasted space in the XIV! As I said, a 243TB 3PAR system using higher performance drives and with wide striping so no hot spots, uses 30% less space than an XIV. The arguments you raise against VMAX are the same ones 3PAR would raise, so you are validating the 3PAR messaging. The difference is 3PAR is a lot more efficient both in terms of space and power.
XIV is definitely an 'interesting' architecture for the 'cloud' but has 2 main issues - power and density.
243TB usable in a rack really isn't that special and when you're building a multi PB cloud then density matters. And even more important is power draw. XIV3 used 8.4kW ... that's a lot of power for 243TB. A comparable 3PAR array, even if you feel the need to spec it fully with SAS drives rather than 7.2k nearline, only takes 31U and 5.4kW. And there are much better ways of hitting 243TB, with good performance, so in reality a 3PAR array would take less than half the space and less than half the power. Could be why 3PAR is in 8 out of the top 10 service providers.
XIV isn't really dense enough for big data, or have enough performance for Tier 1. It does seem a reasonable fit for that Tier 2 type space but so do a lot of other products!
Re: A bit of a waste for Violin to go to Dell
Is there a lot of IP in Violin? Don't they just use Symantec for the functionality? I think the hockey stick growth opportunity for Violin has been and gone ... this market is getting more competitive daily and there are players appearing with much bigger teeth than Violin. When EMC, IBM and HP really get their act together them the smaller players will struggle.
There will be probably be Intel versions of the cartridges as well.
HP sold Violin arrays in theory only, the relationship never got off the ground.
In terms of latency, if you want to share Violin arrays across a few servers then you have to introduce a gateway (x86) server which introduces more latency, and then you still have the fabric latency as well. That's a worse solution than having a genuine storage array that can delivery ridiculous performance and share that as standard. If you just have one server wanting blistering performance then maybe I can see your point, but to be honest, there are even better and lower latency ways of achieving that than Violin.
And the bottleneck in traditional arrays with SSD is the controller not the network. VNX, EVA, etc, all flood the controllers after only a very small number of SSDs. 3PAR can support 200 SSDs without that issue. You're picking at straws. The 3PAR solution might not be absolutely as fast as a little flash only box but is still 500k IOPS+ so plenty for all but the most demanding of apps. But the 3PAR delivers that performance without sacrificing usability.
See, I thought this article was mostly about XtremeIO. Each brick apparently contains 16 x 200GB SSD's but now you're telling me that this isn't a flash array. Sounds pretty flashy to me, as does a StoreServ 7400 with 200 x 200GB SSDs.
And there is a difference between throwing a few SSDs in a disk array and having an architecture that lends itself to supporting very large numbers of SSDs! Throwing a few SSDs in an array will not delivery hundreds of thousands of IOPS at sub millisecond latency ... StoreServ will. Just because HP don't need to bring to market a new specific flash array, doesn't mean they don't have one already!
You say that HP have an all flash array in development - it's already available! You can have a 3PAR array with all SSD drives if you wanted. But the nice thing is, it isn't just an all flash array ... the same mature, stable, highly functional platform can be a hybrid array, or a traditional array. HP are not having to acquire a small flash player, or start from scratch, the same platform hits Tier 1, Tier 2 and all-flash requirements. HP will not be introducing a new product as the existing products already do all this.
Re: FlashRay Interest Abounds! :)
You're right, for almost all vendors there has been a tectonic shift in the market and they are having to rethink as their architectures are 15-20 years old! However 3PAR is designed to and will deliver 300k+ IOPS at sub millisecond latency, with all the standard 3PAR Tier 1 functionality, so no need to start with a clean sheet of paper for HP! HP offers a single product line that can be flash, hybrid or disk without modification.
Re: HP's portfolio is pretty simple in all fairness! - Please
NetApp have just announced 2 new product lines in the same space as 3PAR - those announcements are the whole reason for this article. Flashray and F540 or whatever it is are both different platforms to your FAS line, and both would compete with 3PAR. All 3PARs are forwardly and backwardly compatible, so not sure what your point is there! 3PAR is the same ... if you like the 3PAR functionality then just pick the size of the array you want from a baby 7200 up to a beast of a 10800. They all offer exactly the same functionality and interoperate with each other. It seems that whilst HP is rapidly simplifying and consolidating our portfolio, NetApp is going in the opposite direction.
Not sure which market share figures you are looking at but HP is still tickling along at about 16% which is where we (I work for HP obviously) have been, give or take, for a good few years now. And that's me playing it with a straight bat, if I wanted to pick other market segments that suit HP more I could easily claim to be the market leader but by my own admission, in the one that matters most, we're 3rd. No one in recent years has managed to shift their market share by any significant amount ... NetApp are still second and EMC still a chunk ahead of you. To claim that HP lost 9% market share in 1 year is utter nonsense.
Re: HP's portfolio is pretty simple in all fairness! - Please
Try speaking to your HP storage guy and he'll make it very simple. If you think MSA and 3PAR play in the same space then you're not very sharp! You'd need to live on Mars to not know that EVA was transitioning to 3PAR. Yeah, there are some niche products around the periphery but 3PAR covers everything from very small to very very large, including all SSD / Flash and NAS. There is no other competitor in the market, who covers such a broad addressable market with a single product! IBM, EMC, even NetApp (which used o have a very simple portfolio) all have 3 or more arrays covering that same space.
You're right, there are obviously other products in the HP portfolio but I'd argue strongly that HP has the largest addressable market with it's 3PAR range and less overlap in their portfolio. For example, depending on which way the wind is blowing, IBM will position XIV or V7000 for the same requirement. And they still have their r'ship with NetApp as well. HP have 3PAR as the most appropriate product for all requirements apart from very very small and basic, or mainframe attach. Everything in between, including all SSD and soon all Flash, is suitable for 3PAR. If you include DS8000 and IBM's flash solution in there, then IBM have at least 5 products covering the same space, none of which talk to each other. And the story is similar for EMC.
Apart from the endless renaming, HP actually seem to have the most integrated strategy as recognised by Gartner.
Strange that you would pick on HP's portfolio out of all the options ... someone have an axe to grind? HP's portfolio is pretty simple in all fairness!
StoreServ - the only storage array you'll ever need.
Flash only apparently coming soon, SSD only already available, mixed SSD and SAS already available. One family of products, one rich set of functions across the whole performance spectrum, and about as simple a story as it gets. If you think this is confusing then I suspect that daily life throws you more than your fair share of problems!
Now EMC and IBM's portfolios, they are pretty complicated and not much sign of becoming less so.
Wow, exciting changes there!! Innovation at its' finest!!!
Eating HP's lunch? REALLY??
Shows how astute you are then as you could have made a profit on that!
Re: Compare IBM to HP
But would you have made 25% in the space of a few weeks which is what I've just done on my HP stock (which I also bought at the post-Autonomy news slump). Buying a load of HP stock at sub 13 was a right touch!
Re: Geat ideas Meg
Do you work for the same HP that I do? Everyone I know rates Meg higher than either of the previous 1 and a half CEO's. You read an article in the equivalent of The Sun for the IT community and you assume that Meg is itching to reverse the decision she reversed about selling off PSG.
If you don't like it so much, why don't you grow a pair and leave. It's people like you that are the problem, not necessarily the leadership!
Seems odd that the 2 things you point out as HP's biggest problems are the 2 storage areas they actually have the best technology on the market - StoreServ and StoreOnce are the best mid-range array and the best de-duplicating backup technology around. HP are missing credible NAS offerings - both general purpose and scale out.
What was the chart?
The fact that there is a self service, non-disruptive, and no cost migration method is a big plus. And the licenses on EVA were a few grand not huge chunks of money like on some other arrays!!
And if you're worried that having mastered your EVA (which probably took 1 day), people will struggle to learn to master the 3PAR (probably 1 more day) then you are probably the sort of person who still points at airplanes!
Get your facts straight!
So you didn't spot the 2 x 4-lane 6Gbit/s SAS per controller for drive connectivity then? I guess that means that you endorse the StoreServ approach as a "modern SAS backend solution".
Get your facts straight. The brochure you're quoting from relates to the P10000's which are FC to the drive trays because service providers like to not have to leave free racks for expansion! The new models are SAS back end.
As for front end connectivity, 24 x 8Gb FC will be plenty for most people!!
The F class doesn't use the disk magazine idea in the same way as the T/V did/do either. Both the F Class and the 7X00 use the concept of magazines though, even if a magazine isn't a tangible 'thing'. The 7X00 essentially merges the 3PAR F Class and EVA lines into one.
Matt, totally agree, if you're replacing an array then of course it's a 'rip and replace', but with the EVA to 3PAR migration there's less of the 'rip'! The migration is actually driven through EVA Command View so is very straightforward for EVA customers. It's actually easier than if you were replacing an EVA with another EVA. People love to throw FUD around, would they be calling it a 'rip and replace' if 3PAR was called EVA Gen 6 (or whatever).
Comfortably. Up to 32 (maybe 64 actually) gateways in a cluster and over 800TB storage on the 7400.
Re: 3PAR File Services? @ Man Mountain & AC
Not in the slightest bit defensive, the new StoreEasy 3830 is really tasty! The AV thing is good, plus integration with existing backup approach rather than relying on NDMP. Have seen some really good demos of Windows 2012.
Re: I don't often throw my SME storage money around...
Yeah, the starter kits exist! Speak to your HP storage guy.
Re: I don't often throw my SME storage money around...
Matt, controller spec way beyond that of anything else in the midrange! The performance of these things, and the 4 controller capability, sets them apart. You'll be glad you held off!
