7 vSphere hosts and EVA8400

This is my first experience with HP hardware and HP tech support recommended splitting our 7 host cluster, into 2 seperate clusters.

Are there any best practices or white papers for using vSphere DRS/HA clusters and an EVA8400? The cluster currently has 15 LUN's carved out and presented from our 8400 and i expect this number to grow.

Re: 7 vSphere hosts and EVA8400

How big are the luns?

How many VM's are we talking about?

Any additional information you can provide?



I don't think the doc provided in the link covers HA/DRS specifically, but without any more information about the environment... We rally can't say/help much.

Re: 7 vSphere hosts and EVA8400

I cannot really see a benifit to splitting into two different clusters? Are the cpu's different on the machines?

Re: 7 vSphere hosts and EVA8400

All 7 hosts are vSphere 4 version 175625. These are BL680 G5's with dual port 4GB HBA's. The pathing is set to the default MRU All 7 hosts are identical. 2 hosts are in one chassis and 5 hosts are in a 2nd chassis. (we couldnt do 3 and 4 per chassis because of other blade placement) The EVA has 192 disks all in a single disk group (as recommended by HP)

80 VM's - 90% windows and 10% Linux
15 LUN's most of which are 1TB but no larger than 2000GB. All these luns are vraid5, but we have vraid1 luns presented to other physical servers. We will probably add more VM's and LUN's because we have 10TB of free space.
