[tech] SAN

[Bob Adamson]

Hi All,

If you haven't been in the clubroom over the last few months, you won't 
have noticed the assortment of SAN parts that are dominating the place. I 
think it's time we did something with them.

We have:
2 shelves of 300GB disks
2 shelves of 146GB disks (one of which is the SAN controller)
1 shelf of 73GB disks
2 EMC DS-4700M fibre channel switches
1 UPS which is on the way out

I think we could/should use the extra storage for better webcam footage 
storage, but the disks are pretty heat intensive. My proposal is that we 
use 1 switch, the controller and the 2 300GB shelves to make a miniature 
SAN. This could also potentially replace the two shelves that are 
currently attached to musundo.

Problem: When I plugged in the controller shelf today, one of the 
redundant power supplies blew up, we can get another for ~$200. We can 
afford to get this, but do we want the extra space enough to bother? If 
not, shall we just throw all this stuff out?

Suggestions, comments?
