VPLEX Metro and UCS Boot policy
Hi,
I am setting up UCS blades on a VPLEX Metro and cross connecting the boot from SAN ESXi hosts. Is there a best practice when setting up boot policies for a distributed boot drive? The VPLEX clusters are both single engine and there are dual fabrics between the DCs. My thought was to go with the following:
C1 Hosts SAN Primary boot policy:
SAN Target Primary - C1 Director A EVEN FE (0 or 2)
SAN Target Secondary - C2 Director B EVEN FE (2 or 0)
C1 Hosts SAN Secondary boot policy:
SAN Target Primary - C1 Director A ODD FE (1 or 3)
SAN Target Secondary - C2 Director B ODD FE (3 or 1)
C2 Hosts SAN Primary boot policy:
SAN Target Primary - C2 Director A EVEN FE (0 or 2)
SAN Target Secondary - C1 Director B EVEN FE (2 or 0)
C2 Hosts SAN Secondary boot policy:
SAN Target Primary - C2 Director A ODD FE (1 or 3)
SAN Target Secondary - C1 Director B ODD FE (3 or 1)
Thanks!

Sorry, I had them mixed up, this is the new list:
C1 Hosts SAN Primary boot policy:
SAN Target Primary - C1 Director A EVEN FE (0 or 2)
SAN Target Secondary - C1 Director B EVEN FE (2 or 0)
C1 Hosts SAN Secondary boot policy:
SAN Target Primary - C2 Director A ODD FE (1 or 3)
SAN Target Secondary - C2 Director B ODD FE (3 or 1)
C2 Hosts SAN Primary boot policy:
SAN Target Primary - C2 Director A EVEN FE (0 or 2)
SAN Target Secondary - C2 Director B EVEN FE (2 or 0)
C2 Hosts SAN Secondary boot policy:
SAN Target Primary - C1 Director A ODD FE (1 or 3)
SAN Target Secondary - C1 Director B ODD FE (3 or 1)
Sorry!

Above is a link to the EMC Host Configuration Guide for ESXi. Hopefully this contains the documentation you're looking for.

Hi charba,
This is helpful but I can't seem to find any recommendations or best practices for a cross connected host that boots off of a distributed volume. I can do what I have above but it exposes me to a certain extent because if there is a fabric failure (slim chance), the system would boot across the WAN.

I came across some more documentation while researching this issue, not specifically on a distributed boot drive, but a lot of information that I believe applies to your environment.
In all honesty, the information you're looking for could be in one of these guide and I missed it, I'm looking into this in-between SR work, so I would recommend taking a look yourself too.

Thanks charba1. I can't find the h13813 pdf on support, the link appears to be broken. I will review the other docs to see if I can find anything.
