Adding SSDs to an HD only B1200i

Adding SSDs to an HD only B1200i
Can anyone outline the procedure for adding SSDs to a B1200i to get the SSD tiering feature going? A client has a B1200i with 7 4TB HDs in it now (in bays 0-6). They want to get three SAS SSDs for tiering, and documentation says those need to go in bays 0, 1, & 2). To add those do i:

1) Shut down the Drobo, move the drives in 0, 1, & 2 over to 7, 8, & 9

or 2) move the drive in 0 to 7, wait for it to catch up, then 1 to 8, etc.

Then insert the SSDs in 0, 1, & 2?

Or is there some other method? I can't find any documentation on this, and Drobo support won't answer my questions without an in warranty device.

Thank you.

The SSDs can be added in any slot. There's no need to shutdown or move drives around.

Can you point me at the documentation that talks about using slots 0-2... its in error.

Cheers!

RE: Adding SSDs to an HD only B1200i
btw i think ive also seen some pages in the past which explained ssd features, which had the ssds in the first few slots, (though the picture was probably from an ease of explanation perspective as it was very quick and easy to see a few ssds on one side, with regular drives in the other)

(btw i have XP home SP2, a Drobo v1 with 2x 1TB/2x 1.5TB WD greens, & a bkp Drobo v2 with the same + a DroboShare: unused)
& a DroboS v2 with 3xWD15EADS &2x1TB in DDR mode on win7, & a drobo5D (all usb)
  • btw i did a sustained (write) operation for about 6 hours, and got 13.2MB / sec ...objection? "sustained" :)
    (16.7MB/s on a v2 & 47-96MB/s drobo-s)
