After scanning the past year's ADSM-L postings including Linux in the subject I have the impression that a few people are playing with Linux hosting a TSM service, but real I/O intensive TSM services are still mainly hosted by AIX.
?Is anyone already using or actively planning to use Linux (RedHat EL 3.0?) to host an I/O intensive TSM service similar to any described under the recent ADSM-L thread, "Sizing an AIX platform and tape libraries"?
We believe we are approaching the maximum that can be achieved w/ TSM: v5.2.1.3 OS: AIX 5.1 (64bit) CPU: IBM 7025-6F1 w/ 4 * 750Mhz proc's + 3GB RAM SAN: 1 Gb w/ EMC Symmetrix 8830 LAN: 1 Gb Ethernet ATL: IBM 3494 w/ 6 * 3590E drives IBM 3584 w/ 4 * 3580 LTO1 + 2 * 3580 LTO2 drives
This configuration is successfully supporting our current ITS TSM service (see details below), but we believe we either need a major performance boost or to split this load onto an additional host platform: Linux, Win*, or must we remain w/ AIX for I/O performance? to handle expected additional growth.
Which platform have you chosen (or would you choose) for similar TSM service?
Yale ITS TSM Service: -------------------- Active Clients: 2400 <= 3d, 2500 <= 7d, 2700 <= 35days
Servers: 151 WinNT,2K* 105 Linux 20 Solaris 9 AIX 7 SQL-BT (Oracle) 3 Mac 2 TDP's: MSSQL,MSexchg: 2 + 1 [new] 2
Personals: 2549 WinNT,2K*,XP 2230 Win98,ME 26 Mac 183 Linux 50 Solaris 5 AIX,DEC*X,HPUX,IRIX: 1 ea. [new] 51
Expected growth: +500-600 clients for several years +20% data for existing clients/year?
TSM DB: 75.7% of 160GB BAckup DB w/ LTO1 HCmpr. takes 2.3h EXPIre Inv examines ~6M obj, deletes ~1M obj. in 8-9h
Disk STGpools: 600 + 180GB Nightly Backup Period: 15:30-08:00+ Weeknight Backup Load: 500-650GB+
