SAN EVA 6100

Hi All,

I found the information that EVA 6100 can run up to 1380 Mbps maximum throughput (172.5MB/s).
When this throughput can be achived? Is that all drive read continiously?
How much is the production throughput that people normally get?
In my environment, average throughput is about 100 MB/s.
Does Anyone get better throughput?

Re: SAN EVA 6100

I check the HP EVA spec again and max throughput is 1380 MB/s not 1380 Mb/s.

That means i'm currently running at arround 8% of max throughput?

Backup is running using multi-stream with 4 NICs gigabit LAN connect from backup server to 3 diferent hosts.

Ken, just ignore those stupid numbers.

These are generated using special test programs to stress the controller's CPU and cache memory and demonstrate that these components are not the limiting factor.

The numbers have *nothing* to do with reality.

The limiting factor are the hard disks. Best case scenario is doing sequential 128 KB reads from a RAID 5 or RAID 0 vdisk.

But when you have real operating systems and applications acessing an EVA, you have a mix of reads and writes of sizes smaller than 128 KB. Each disk can do 130 - 160 operations per second, that's usually the limit. For example 40 disks x 160 IOPS x 8 KB = 51 MB/s.
