We are looking at the Cisco Extended memory blade servers and trying to "pack" as many VM's as possible on a single server using 10G ethernet and iSCSI.
Does anyone have any experience with what is possible on this hardware.
I am working with Cisco UCS Blade.UCS has memory extention chip on full width blade which supports max of 354 GB.If you have any query please feel free to ask me.
Half width blades are with 64 GB RAM and full width blades are with 128 GB , I have tested 30-35 VM's (Combination servers and desktop) in half width blade,CPU utilization not more then 60% even at all the VM's are fully utilized.
I am setting up to test the performance with NFS Datastore over 10 Gbps Ethernet.
It performs low while using iSCSI datastore on EMC storage over 4X1Gbps etherchanneled link between ESX and Storage.
It performs good with FC Storage.
1.Still has to test the performace of 10 GE link (as there is no 10GE iSCSI storage available).
2.Performance of Nehalem Processor
3.palo CNA adaptor(bypasses the vmkernal)
