Hellow, We are in the process of update our library environment. We are consulting some VTL maker to optimize our "backup image" process.
Our idea is : Site 2 : ITSM servers => RandomDisk(~2TB) => VTL site 2 ~40TB (MigDelay ~ 30 - for on demand restore purpose)) => Library site 2 1000 LTO3 Slots and ~15 LTO3 Site 1 : => Library site 1 (backup copy x 2) 1500 LTO3 Slots and ~15 LTO3 VTL is not used to generate TAPE (we plan to used TSM migration process, we don't want to generate new production process and keep DRM ITSM module). In our production we have : Site 1 : (production servers level 1 ~40) Disk (8TB) => Synchronous replication+clone => Disk site 2 => (standby servers, not the same characteristics as production servers) (production servers level 2 ~300) Disk (40TB) Site 1 and Site 2 are in the same campus. We have also a "passive" DRM (manual offsite tapes based DRM) for the campus. We are generated our backup image from site 2 for data level 1 for offsite DRM purposes, but our standby server are poor server (IBM B80 for instance). For speeding process, we plan to do all backup image in parallel with a VTL as target. We also want to try Active Collocation on VTL (TSM 5.4) for full restore of servers level 2. ITSM Servers are : 2 LPARS from p595, today our LPAR are not well balanced for security reason : * LPAR1 1 processor, 2GB RAM, 50GB DB, 4x2Gbit/s IBM6239 * LPAR2 4 processors, 8GB RAM, 290GB DB, 7x2Gbit/s IBM6239. We plan to split this ITSM instance in 2 or 3 using AIX 5.3 micropartitionning. Any experience with VTL from : ADIC/QUANTUM IBM SUN/StorageTek or with other solution. I'am interested about integration of this solution with ITSM and performance consideration. Thank you for your advice.
