Backend/Storage Server Help...
 

Hellow folks, I am researching for an backend server solution and I need help..

What I want is to Have 1 server with only applications installed on it.., and another server (backend/storage) with all the data and DB.

Can any 1 suggest me architecture and from where to start, what do I need like software and how to setup both servers...


Thank you.

Two words .... "it depends".
What applications are you setting up?
How large is the DB(s) going to be?
Will there be other files size requirements?
How much space will the applications need?
Will it need to be scalable? That is, do you see a need to add more servers at a later stage for growth?
Will you need shared storage options available to you?
Are your filesystem requirements (application type) for speed or for size or both?
What is you anticipated number of users hitting the application during peak periods and how does that translate into iops on the database? (how many read/write operations a second)
Do you have an existing setup that you can get some baseline figures from?

The first applications I can think of will be the basic user accounts and E-mail server...
I would not need to add more servers at a later stage for growth.

Are your filesystem requirements (application type) for speed or for size or both?
Both.

It will not have very heavy load.

lets say that I have 1 server with linux installed and lots of user accounts (20-25 accounts that use X , not always 20-25 at same time.. normally 10 accounts at same time ), E-mail server...etc.

And one separate server for the data from the user accounts, and storage of the E-mail data...,

Actually all the necessary applications will be installed on the 1st server...and the second will be storage/backend with all the application files..

So if something happens to the application server, the data will be safe in the storage server.

1st.. Whats the difference between NFS (Network File System) and RFS (Remote File System) (I have read alots wiki but I cant figure it out?)

OK, thats my plan..

[Machine 1] The Storage Server It will have 4-5 HDD - 500GB Each .., and I will install NFS Server...

[Machine 2] The App Server.., I will install Linux With X (Gnome) and The Users /home/ dir will be mounted from [Machine 1] (NFS Client) so when I add new user, his home directory will be in the storage server...

The E-mails will be mounted too, so they will store at the Storage Server [Machine 1] ...

Is that Correct?
