Pros and Cons of SAN

By boyhowdy ·
I'm looking for a good independant study on using a SAN for a central repository for Web data. Providing a central location for data seems like a great idea. It's creased speed and ease of deployment and infrustructure seems great. But what happens when you have to take down you central data repository for a firmware upgrade. What about several services writing to one location?

I need to find a good study. Most of the ones I have found are done by the manufacturers and they seem a little biased.

Thanks for you help.

Pros and Cons of SAN

Greetings,

You are right, doing an Internet search will give you a lot of "biased" manufacturer's evaluations. But in all fairness to them, there is a lot of good information if you "read between" the bias.

However, a couple of other sources:
1. TechRepublic: Do a search for "SAN" right here at TechRepublic, and you'll find numerous columns, articles and discussions on the subject.

2. Microsoft knowledge base:
Q260176 = Description of System Area Networks.
Q264135 = Differences with System Area Networks and Storage Area Networks

Keep this question open for a while, and I'm sure you'll get a lot of great ideas and/or resources.

Regards,

Maxwell

You may find lot's of info about SAN and it's benefits.
Having a central repository of data have many great advantages such as:
1.- Adding more disk space (specially usefull if you are growing!)
2.- Saving money in HD space. Great!
3.- Only one backup tech,. used to backup many servers.
4.- Snapshot
5.- Very usefull for large amount of data and few servers
Disadvantages:
1.- Only one point of failure!!!
2.- Not every application is SAN aware!
3.- No so easy to extend and NT partition,still need to format and restore!
4.- Expensive if you have moderate space allocated. (<100GB)

I dont know of any studies per say, but I was looking into the same thing, and I did quite a bit of research, our company held of not because it wasnt a good idea but because of the cost. We wanted to have about 15 NT Servers accessing the SAN through a fiber optic backbone. Basically everything in the system was re-dundant so we would never go down. Of course the hard disks were hot swap, and each server would have had 2 raid cards, the way we would have set it up is that when a server went down, another server would pick up the services until we got the broken one up and running. I was quite impressed. I dont remember the mfg because we went to a VAR the specilaizes in this technology and who would provide the complete package. THis was about a year ago, and we were looking at spending 100,000 bucks on the complete system, so it wasnt cheap, although I am sure there are much cheaper solutions out there. (the Var had cheaper solutions but we wanted 100% redundancy on the whole network).
So, the only negative I encountered was price, and with a solution such as this I actually rate the service of my vendor more important than the mfg.
