Hi all
As I value all your opinions tremendously, I thought I would bounce this question to all. Current Config. TSM 5.5 on AIX 5.3 ML4 on p570 LPAR - 2GB Memory 16GB TSM DB 95 Nodes +- 2-3 TB data daily EMC SAN (All Raid Groups are Raid 5) 1.5 TB Disk pool TS3310 Tape Library with 108 Data Slots, 18 IO Ports, 4 x 3576 LTO3 Drives ALL Connected via FC Mac data Switches at 2GB TSM DB located on Local Disk, Balance on activity on SAN Large IBM Blade centre running Native as well as VMware VM's i.e. EXCHANGE Server, File Servers, DC's etc All Windows OS, AIX OS, and MSSQL backups go to DISKPOOL MONTHLY, WEEKLY, YEARLY are sent to TAPE, as well as file Servers daily Current Backups for Informix and its logical logs take around 4 hours to Tape. 280GB Database. When all drives are busy, logical logs are not backed up in some instances for 2-4 hours, as I do like to give reclaim and admin tape resource processes max resources. I am not utilizing LAN-FREE yet. I have 2 sites running the above, 1200km apart Requirement I would like to have Informix, and its logical logs backup to a medium that is permanently online and not affected by tapes drives being fully utilized. My gut feel after listening to all the discussions posted here is to look at a VTL solution or a NAS device that would be migrated daily to tape. I also do not want to duplicate the data on to another disk device purely to put the business at ease when the risk of failure on a VTL Disk or NAS Disk device is the same as the logs waiting to be backed up on a RAID 5 LUN in the SAN. The business cannot afford to have a disaster that would require rolling back more than 30 minutes, so VTL to me does look preferable. We are also in the position to have the device located at another location on our site to reduce risk as we have a large manufacturing facility and it would still be FC linked. Is anyone using this type of solution as I have explained above? I hope I have explained the scenario sufficiently and look forward to your comments, observations and suggestions.
