Hello All, We will be phasing out our OS/390 mainframe in the next few years. Currently, we have our TSM server installed on the mainframe, so we will need to move it off and on to something else. Based on conversations to this list and the Redbook, IBM Tivoli Storage Manager Implementation Guide, I believe that we definitely need to move to AIX. The above Redbook is not very helpful as far as sizing the AIX machine, saying that it is an "inexact" art. Here are our current and future requirements:
1) Right now we are backing up about 150 GB/ night, but we need to add Exchange and a new student information system (Banner) to this. We are estimating that we will soon grow to at least 500 -600 GB/night. 2) Workload consists of 95 clients, consisting of from small 20-30gb Unix and Windows systems, to DB (Oracle) and file servers with half to one terabyte of storage. This will grow to 120 or so clients soon. 3) We are currently storing 10.7 TB total data in two libraries, one local tape library and a second copy of everything at a remote tape library (3494 ATLs w/3590 E drives). Looks like this storage could triple, given how much we will be backing up each night (15 TB in each location). 4) Network is Gigabit Ethernet. 5) We would like to use one large server vs. multiple servers. Does anyone have a similar scenario that is on AIX that works well? Please describe, including tape libraries! Does anyone know of any additional guidance available on choosing an AIX platform size and choosing an appropriate tape library? Thanks!
