HP is building a low-end 3PAR array with data migration software to convert the EVA customer base to a 3PAR customer base. We hear HP will use SAS disk drives instead of the more expensive 3.5-inch Fibre Channel drives. This will make it easier to substitute 3PAR's V-, T- and F-Class arrays s for the ageing EVA mid-range, dual- …
3PAR VSA unlikely?
"....3PAR array controller software implemented as a virtual SAN appliance...." Not sure I see what advantage this would offer over the P4000-based VSA? I can see hp looking to make a new entry level 3PAR array as the F200 is a bit of a demo toy at best, but I would expect any F200 replacement to have two proper controllers to protect the 3PAR image as a fully-redundant array. It might make sense for hp to make a new product below the F200 using one controller ASIC rather than two, which would be cheaper but remove redundancy, maybe just for archiving.
Re: 3PAR VSA unlikely?
I too see the likelihood of a 3PAR VSA unlikely. The F200 is not a demo toy, it is a dual controller system, the only difference between it and the F400 is it is a 2-controller vs 4-controller(customers can of course run only 2 controllers on the F400). Any new low end box would also be 2-controller, since it'd be much cheaper obviously. The main downside to the F-class in my opinion is the number of PCI-X (not even PCIe) slots available for expansion, there isn't much. I'm less interested in driving tons of throughput as much as I am using more direct attach, which applies pretty much just as much to the F400 as it does to the F200. Of course any two-node 3PAR system can't benefit from Persistent Cache which really is a nice feature to have available.
The only systems that have more than one ASIC per controller is the V class. Everything else in their history has one ASIC per controller. I suspect any VSA that may come out would be for non production use, mainly for training/testing purposes, test out things on the CLI or GUI and simulate things. But I think even that is a stretch and may be a while (years) before anything resembling something like that sees public light.
Redundancy is provided at the controller level, to a (much) lesser extent at the ASIC level on the V class. While the failure of one of the ASICs in the V class could result in the controller continuing to operate I can't help but think the number of scenarios where it fails in the right way is small enough to not make much of a difference, and the customer should not put much weight in the redundancy with the two ASICs, they are there for performance rather than availability.
3PAR also has always been anal about high availability, not allowing customers to buy single controller systems, always having to buy disks to provide redundancy across at least two drive cages.
About damn time
We were looking to purchase 3PAR, but they couldn't tell us anything about future products, I.E. what they were going to do about the fact FC disks are stopping production shortly. Even with an NDA! Bought from another vendor in the end :(
It's a shame because I still think the 3PAR premise is awesome, way better than the system we bought in the end.
Long term EVA customer (3000, 4400) now moved to NetApp. Bye bye HP and your shitty software.
Re: Too late
EVA is done, being replaced with 3PAR at an HP pace. NetApp has had its dedupe day in the sun. The big players have closed the gap and surpassed them in some areas. There are better, less costly mid-range offerings, IMO.
HP have a mid ranged SAN called a P7000
This doesn't sounds anything like the IBM V7000 SAN, which comes with lots of fluffy easy to use software unlike the HP offering.
Fluffy ease of use software... like in line, real time compression and SVC virtualization? V7000 is the most feature rich mid-range array on the market.
