Multisite P4000 in VMware

[richy_d]

Hi,

We have four P4300 nodes, two in each site (Main/DR) connected by 2Gb Fibre however the two in the DR I am in the process of setting up. I beleive I can still use the same virtual IP address for all four nodes or is that not the case whilst I have setup 2 sites within CMC?

Do I need to make further changes in the virtual networking on vSphere i.e. create a seperate iSCSI vSwitch with the DR side for failover or does the Failover manager handle all this?

I'm one of the guys who posted a bunch of comments on that blog entry.

We ended up going with a stretch cluster i.e. multi-site within the CMC but a single VIP on each cluster.

The issue is that the vSphere iSCSI kernel can't route.  If your iSCSI LAN is connected by fibre and the latency is low and the reliability good, there seem to be few good reasons not to just go with a stretch cluster.
