I'm trying to correctly setup a HA storage system for HyperV at the lowest possible cost. Speed is not a big issue because the hyperv hosts will be limited by 2x gigabit nics to access the iscsi targets.
Best practices for HyperV HA show a minimum of having 2 storage servers, 2 enclosures with each storage server connecting to each enclosure, and both enclosures storing the same data.
I've been considering HP's MSA50, 60, 70 all of which can support 1 or 2 controllers and each controller has 2 SAS 8088 ports but 1 is marked in and the other out, and these are generally used to daisy chain enclosures. The SE3016 is also popular on this forum, but only has 1 IO set (in and out). I'm assuming both the HP and the rackables are SAS 3.0gb/s enclosures, which is fine in terms of speed for my needs.
Are there newer SAS enclosures that are designed differently for the ability for to storage servers to both be attached? Or do the older HP MSA products support that? The HP's mention something called dual domain, but as far as I know that's just a form of MPIO, and is designed to add redundancy between 1 server and 1 enclosure, by running 2 cables to 2 separate HBA/raid cards.
I would most likely use an HBA, because based on the Microsoft koolaid ive been drinking its better to handle all raid as "storage spaces", and id love to for once be able to read smart data directly while in "raid".
If anyone has experience with the msa50, 60, 70 enclosures and knows some tips on how to use them / what HBA's play well with it, Id love to know.
Anyways I have a lot to learn on this topic, open to any information / suggestion.
