Storage Virtual IOPS

[CB221]

Hi

I have a requirement for 8000+ of IOPS in a storage cluster.

I was looking at the HP StoreVirtual 4530 4TB MDL SAS Storage (12 x 4 TB) 6G 7.2K disks.

However I have no idea what level of IOPS this will provide and how many nodes I would need.

If this doesn`t provide what I need, do you have any other recomendations of any other StorageVirtual models that can provide this number of IOPS?

Thanks

Please let me know the read and write percentage of the IOPS you are looking for?

Hi Mr NKC

Thanks for the reply.

This will be 50/50 read/write using around 8000 IOPS.

I`m also interested in the way this is worked out, i.e do you have a manual calculation so I can use this for different future
IOPS and read/write ratios.

Look forward to your reply.

Many thanks

You could try using this IOPs calculator...might come handy..

To be honest, I was looking for a HP storage virtual SAN that matchs around 8000 IOPS and 50/50 read write specification.

Can you provide this information with the offical HP stats?

Physical disks are your building blocks to everything.  It sounds like you need a professional to design this as unless you need a LOT of physical space, getting 8000 IOPS steady state out of 7.2k drives is going to take something like 200 drives which would be something like 17 nodes in a cluster.  Seems like SSDs are going to be your answer either with the hardware appliance flavor or building your own through VSAs (thats generally most cost effective).  

If you can't answer those questions yourself you should really seek out a local VAR to figure out what you really need as 8000 IOPS is nothing trivial and it need someone experianced to design.

8000 IOPS, 50/50 R/W  and how much usable storage space you need?

Sounds like you would need all SSD storevirtual VSA to do this with reasonable number of nodes!

Hi @CB221

I was not able to find any information on IOPS measurements for the StoreVirtual 4530 but I did find some useful information for the HP StoreVirtual 4335 Hybrid Storage F3J70A.  It has  been measured at 96k IOPS and 2.64ms average latency in a 4k random read test without the driver in place and 141k IOPS with 1.81ms average latency with the driver installed by storagereview.com.  Here are the QuickSpecs for your reference I am not a storage expert myself but I do have colleagues who are.  Can I put you in touch with a storage specialist who can help you figure out if this is in fact the right solution for you?

You will need at least 6 4730 systems to achieve 8000 IOPS @ 20ms for a 50/50 r/w workload ... assuming here that you really can create sufficient load with your server.
