Eliza,
Why not
Yr1
Convert one D12 to D22. Replace 2x 3590 with 3592
Yr2
Replace 2x3590 with 3592. This is possible because a D22 holds twice the drive
density of a D12
Yr3
Given that the 3592 is faster than the 3590, it may not be necessary to add
more 3592s. Just remove the remaining 3590s, and replace with bare slots. If
you do decide to add more 3592 drives, add them into the D22 frame rather than
converting another one.

We have a 3494 tape library with six 3590E drives.
I am looking into upgrading the 3590E drives to 3592 drives.
current setup:
TSM server 5.2.3.3 on AIX 5.2
3494 with 3 frames: one L12 and two D12s
six 3590E tape drives
server and 3590E drives connected to two 2109 SAN switches.
Because of budget constrains I am thinking of replacing a frame and
two 3590E drives at a time and spread out the cost over 3 years.
Can someone give me a rough cost estimate before I even propose it.
Is there anything I missed in the following 3yr plan?
Year 1:
convert the frame L12 to L22
replace two 3590E with 3592
300 new 2592 tapes
Year 2 and 3:
convert the frame D12 to D22
replace two 3590E with 3592
300 new 2592 tapes
Thanks,
