Performance on EVA 6400/8400

Hi all,

A need to configure a new storage for my data center, the application user already gave me their IOPS number for each application, for the capacity requirement i need to go with EVA 6/8400, but i can't find the performance white paper that has the IOPS statement.
Anyone knows where to find IOPS data for those storage systems?

I only have the whitepaper for EVA 4400

Thanks.

Hi Indra,

Here are the Performance White papers
EVA6400: http://h20195.www2.hp.com/v2/GetPDF.aspx/4AA2-9570ENW.pdf
EVA8400: http://h20195.www2.hp.com/v2/GetPDF.aspx/4AA2-9569ENW.pdf

The performace is limited by the type and amount of disks. Usually you reach that limit before saturating controller CPUs or ports.

Also, the type of RAID (0/1/5/6) influences the read / write performance.

@susanta dutta, yes techub also gave me those whitepaper, but it only for the benchmarked configuration, i can't count my own configuration IOPS

@vcespon, those details it's what i need, at least IOPS/disk type/models.

@vcespon

Why at those sources has different number??

#FC 10k drives = 120 IOPs or less
#FC 15k drives = 170 IOPs or less

15K Fiber Channel
VRAID-1 115 VRAID-5 73

10K Fiber Channel
VRAID-1 83 VRAID-5 53

But a will use the less number for safe ^^,
Many thanks vcespon

Re: Performance on EVA 6400/8400

A '15k' disk does 15,000 rotations per minute - that is 4 milliseconds per rotation. A '10k' disk needs 6 ms/rot.

So a '15k' disk's rotational delay is a bit shorter and assuming that the positional delay (moving the head between cylinders) is about the same it can perform more I/Os per second.

@Uwe Zessin
what I mean is at those 2(two) sources, the same 15K HDD has different IOPS score.
I know that 15 K has higher rate than the 10K, Now I just waiting for the SSD IOPS Benchmark, it will be soooo fastttt.. (at soooo higgghhhh cost :P )

Re: Performance on EVA 6400/8400

The numbers in "Basic EVA Performance Guidelines" are the maximum you can expect before latencies go above 15 ms read / 5 ms write.

Also, they are total IOPS, like in an VRAID0 disk. In case the vdisk is VRAID 1 or 5, there are more operations done per read or write.
