Wed, 18 Nov 2009 20:57:20 +0000 http://blog.scottlowe.org/?p=1742#comment-46676 I second your request for clarification of the number of iops to use with vSphere and RR MPIO. The recent multi-vendor post on iSCSI mentions setting it to 3 if you use EqualLogic storage, however when I contacted EQ support and posted on the delltechcenter.com forum, I was told maybe 300 would be better, or my personal favorite "It depends so try a bunch of settings and monitor your performance for what works for you". If anyone can shed light on this setting, please do so! http://www.delltechcenter.com/page/A+%E2%80%9CMultivendor+Post%E2%80%9D+on+using+iSCSI+with+VMware+vSphere I second your request for clarification of the number of iops to use with vSphere and RR MPIO.
