Help understanding SAN technology
Posted on 2007-12-06
My company is relatively small but looking into getting a SAN to help manage our electronic data growth so I'm looking for some guidance.
First please clarify the following:
1. When using a SAN, I can make it so that my other windows servers "see" these hard drives and think they are directly attached to that server. i.e. it's not a shared folder that I would have to map a network drive to right?
2. Does the previous apply to virtual servers in a VMWare environment also?
3. My SAN OS/Controller/Config allows me to allocate hard drive space to my other servers, and also allows me to increase/decrease this amount when necessary.
Secondly, any input on choosing a SAN vendor would help. My biggest requirement is that while we don't need a lot of space today I want to have the option to grow in the future without having to purchase a lot of extra hardware (basically only want to buy additional hard drives). I'm open to iSCSI or Fiber Channel but cost is a big factor in my decision.
