Re: How does multipathing work?
What a great point Chris. Really important to remember in all aspects of virtualization. Their are limits and you want to be below them.. I have never thought of using a a\p array to enforce them....
View ArticleWill multiple VDs in RAID allow additional datastores?
I am setting up an ESXi Test Server. I have a Dell R510. I found some SATA disk drives of various sizes I inserted them into the 8 slots. Slot 0 -- 2TB drive Slot 1 -- 2TB drive Slot 2 – 1 TB drive...
View ArticleRe: Will multiple VDs in RAID allow additional datastores?
Hello, Yes, each virtual disk can be added as an individual datastore. I'd suggest, instead of installing ESXi on one of those VDs, use a flash drive and leave the VDs for VMs. All the best, Mike...

A general best practices from all SAN vendos is to never use WWNN for zone definitions.

Well, that's good to know but:-SAN boot target and zones are different (related) things-I'd love to know the "why", not only the "what" to do. AFAIK, zoning is just a security (authorization) method...
View ArticleRe: How does multipathing work?
Chris, thanks for joining in, but you lost me there. What I am inferring from your response is that an individual SP in an A/P array has way more power than an individual SP in an A/A array. I.e. if...
View ArticleRe: How does multipathing work?
As I mentioned above I had never thought of using a a/p array to enforce fault tolerance but it's true it does help avoid over subscription by strictly enforcing it. Performance on the A/P array would...
View ArticleRe: How does multipathing work?
I'm afraid I still don't get how A/P is any better than A/A, post SP failure. Lets look at two hypothetical arrays using round numbers, one A/A and one A/P. Each houses 1 TB of net storage divided into...
View ArticleRe: How does multipathing work?
Let's not think of it as better or worse. They're just two different ways to design a storage array.

View ArticleRe: How does multipathing work?
I wouldn't quite phrase it that way. A/P is definitely not an SMB thing. It's just an architectural choice. An active / passive (A/P) array is designed specifically for fault tolerance. For each volume...

Hello, This doesn't sound like a VMware-specific question. Rather, it sounds like a Microsoft Windows question. Just ensure that the hosts on which the 2008 VM runs can see the same RDMs and follow...
