Environment recap
Environment - Recap

Vmware ESXi 5.1




ESX Licenses = 40 Enterprise Plus Licenses

Servers – four refreshes (PE2950 → R900 → R810 → R820)

Memory expanded
Memory Expanded

2010: 2.4GB RAM/Server

2013: 5.7GB RAM/server

Clusters: 2.0/2.8/1.0 T

1000+ Vms?

Example: Sharepoint 2013


Clusters: 272/307/150 Ghz

Example: Security Cameras


NFS mounted from Netapp Devices

Data retained in 2+ places*


10G if > 25 VMs

VM Side


No Data loss – Same

Issues (2013):

June 2013: Driver FW issues (tg3)

July 2013: Dev storage latency issues

July 2013: Datastore full when not

Sept 2013: Driver FW issues (igbx)

Nov 2013: ESX Host became slow
