Re: Help with 4000 upgrade
Yes, You will operate in degradded mode till the drive is replaced and resynced in to the set. The problem with a raid 5 is, if you loose another drive before you get it replaced your SOL. And Degrade speed is 25% ?? of normal.
It's not any different than running a mirror (raid1) execpt there is no degrade mode. Works are normal speed. I think the 4x00 can run 2 raid 1 shares. You loose some speed, but may be able to load them with 4x 750gig drives. Thats like 2 x 720gig usable space. Just if it had to power to spin them up.
ALWAYS setup the email notification on any network device, and test to make sure it works. The earlier you know you have a problem, the better off you will be.
I thought I read some where that the best raid 5 performace accours with 7 drives, then have a hot spare. I don't like a hot spare if its spinning at speed. It should be in hibernation mode till needed.
