    SAN servers

    Locked

    Hello,

    We are starting to look at getting a small SAN for our business (maybe). Now I have never worked with a setup such as this, but I need to know what to look for. I know that there is a basic setup of a backplane that the drives plug into etc… and that if you want to expand you get buy more Hd’s or another backplane / Hd’s and connect through fiber channels etc… But how does this actually work?

    Sooo…

    #1 If I buy a HP / IBM / DELL SAN, and I have 1.5 TB of disk space, how do I partition this disk space into say 4 servers running 4 seperate servers with DB’s?

    #2 What about memory & processors? If I add more disk space to a SAN do I add more processors or memory?

    #3 Redundancy – How is this accomplished? Is this where I buy another back plane and mirror one to the other? Or can you set RAID arrays on this?

    #4 Is there a good white paper that I can look at for this type of info?

    Tx

      1. Each type of SAN will provided some sort of software for you to use to carve out LUN’s and determine which servers use what. I am personally familiar with Dell, IBM, and EMC SAN’s. They each have many pro’s and con’s but the software used to config the SAN is pretty good on all threee EMC probably being the best software.

      2. No you do not need to buy more memory and processors to add more disks as long as there is still room in the block that you have if not than you need to buy another block to add onto the one that you have. Those will come with Mem and CPU.

      3. The purpose of a SAN is to provide a complete level of redudancy. There will be two backplanes, two power supplies, two CPU’s, Two sets of mem, and so on. Everything is redudant so that if one backplan drops the other picks up and the same goes with mem, CPU, Power, Drives, Fiber cards switchs and so forth.

      4. Not familiar with any white papers but I am sure that you can find some goods ones for each type on their respect websites.
