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. Regards Steve Steve Harris AIX and TSM Admin Queensland Health, Brisbane Australia >>> [EMAIL PROTECTED] 23/10/2004 1:53:51 >>> 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, Eliza Lau Virginia Tech Computing Center 1700 Pratt Drive Blacksburg, VA 24060 *********************************************************************************** This email, including any attachments sent with it, is confidential and for the sole use of the intended recipient(s).
