I have a few questions related to SAN. Im beginner and Im trying to setup SAN based on the readings and materials what I find on the web.
First Id like to give You configuration and than tell You what are we planning to do.
MSA 1500cs two redundant controllers
Two Silkworm 200e on each 8 of 16 ports enabled
MSA 30 14 x 300 GB 10k
MSA 20 7 x 750 SATA
Around 15 servers, mixed - w2k3, few w2k, and 4 VM ESX hosts on which are around 15 machines installed, also w2k3.
We are planning to put HBAs in each server, maybe in some servers (which are crucial) put two, so we can get full redundancy.
Port licenses are not problem, if we need more well buy POD.
First of all we are setting this because of backup, so that we can ease LAN traffic.
Our plan is to backup the DATA from few servers ( 5-7) on central storage ( msa 20 ), and backup of all OS. Then we want DATA to transfer to tape.
The problems what we encountered:
- How to backup to central storage MSA 20, problem with different OS, heterogenous environment?
- How to share that storage among all servers which will put their DATA on it, and than from that place transfer all on the tapes? We are using Veritas Backup exec 12d.
- How to divide the storage (MSA 20), we are thinking about RAID 5, one array for Backup OS, and one for the DATA.
Thank you very much in advance, for all suggestions and help.
