How many hosts served concurrent on VA7410?
My company want to estimate that how many hosts able to served concurrent on a VA7410 disk array....
We have a VA7410 disk array production now, it also include hd 36GB(15K) * 37, and service server 1 and server 2 in production(reference below)...
Before that, I have collect average IOPS (host) for those production servers analysis.
server 1 : 3000
server 2 : 1000
server 3 : 600
server 4 : 150
server 5 : 75
scenario 1 : server 1 and server 2 run in a va7410. server 3 & 4 & 5 run in a va7110 (36GB 15K * 15). va7410 / va7110 connect to SAN.
scenario 2 : server 1 & 2 & 3 & 4 & 5 run in a va7410. va7410 connect to SAN. How many hd we need to install on va7410 disk array...

Re: How many hosts served concurrent on VA7410?
You will get a significant boost if you go for 10K disks in the array if it supports them. You will get better performance in a raid 5 scenario with more disks.
I'm probably missing something, but i can't tell you how many disks based on the detail of your post.

Re: How many hosts served concurrent on VA7410?
My current production environment,
disk array : va7410 + 36GB(15K) * 37
server 1 : rp7410 (8cpu / 16G ram),IOPS=3000
server 2 : rp7420 (8cpu / 16G ram),IOPS=1000
server 3 : K580 (6cpu / 6G ram),IOPS=600
server 4 : K580 (4cpu / 4G ram),IOPS=150
server 5 : K380 (4cpu / 2G ram),IOPS=75
server 1 / 2 now share one va7410.
server 3 connecting a 12H with 18G(10K)*8
server 4 connecting a 12H with 18G(10K)*12
server 5 connecting a third-party diskarray.
We going to implement this va7410 in a SAN environment, and server 1/2/3/4/5 will share this va7410.
My question is how many disk should be on this va7410, then IOPS or performance able to support those 5 server for production?
Thanks,
Jack Fan

Re: How many hosts served concurrent on VA7410?
Jack,
One consideration is that server 3 might be at the max of the 12H so that if you connect it to the VA7410 it would produce more I/Os than you are currently getting.
I addition to the IOPS, it would be best to understand your read/write ratio. HP Storage Specialists can tell you how many IOPS (read, write, 60/40 mix) you can get with a specific number of drives assuming certain average block sizes. So is a 60/40 mix good for you or do you need to interpolate between read and write numbers?
