Hi,
We have a pool of 34 linked clones (floating pool) in use for a lab (school district) and during login, I'm seeing some huge IO numbers for the datastore(s) when all of the students are first logging in. I know there is going to be a spike during simultaneous logins (boot storm) on linked clone pools, but this much and for only 32-34 desktops?
VMware environment is - View 4.6, ESXi 4.1 U1, 4gb fiber attached storage, single path (Only 1 HBA uplink per host at the moment), Xiotech ISE 5000 SAN with approximately 6300 IOps attached at 4gb. Note: There are only about 50 desktops on this storage right now.
Virtual Desktops: Windows 7 Pro 32-bit, 1GB RAM, customized using the VMware guide - all non-essential services disabled, windows updates disabled, no AV at this point, floating pool, and no roaming profiles.
Users are not complaining about the speed of the desktops; I just want to make sure that as we scale up more and add more labs that these IO numbers are normal. We could potentially have 3-4 labs all logging in at the same time. Obviously, once things settle down and the students begin to use their desktops as normal, the IO settles down and things look great.
I've attached a screenshot from the Xiotech ISE showing the IOps for the 3 hosts in the View cluster.
Thanks!
