We actually will be using ONLY local storage... Dell R515's with 8 450GB |
| 17 |
SAS drives in RAID10 (with one hot spare assigned)... |
| 18 |
|
| 19 |
A decent SAN wasn't in the budget (yet, but we may go that route in a |
| 20 |
year or two)... |

This is a new install, so not an 'upgrade'... |

I do plan on having a couple of large SATA drives in RAID0 (for speed) |
| 35 |
for temporary snapshots (which I then backup using rsnapshot or my VM |
| 36 |
backup s/w) and for if I ever need to add some drives to my RAID10 |
| 37 |
(probably won't, the 1.7TB I'll have is 4 times what we have now which |
| 38 |
is only 70% utilized)... |
| 39 |
|
| 40 |
I get the CF cards today (already have the adapters), so we'll see how |
| 41 |
this goes this weekend... |
