restructure of exchange server
I just wanted to find out other NM and technicians view on this and offer any advice and find out what type of setups you have in your school.
We currently have an exchange server which has about 90 staff users with mailboxes. I am under pressure to get our students on email as well. We have about 700 students.
I just wanted to get some feedback on our schools have their exchange setup.
For schools who have all their users on exchange email. Do you have 2 separate servers, one for staff and one for pupils or do you have 1 server with all the mailboxes?
Our current server which hosts exchange is a dual intel xeon 2.8ghz, 4gb RAM and 700Gb RAID 1. Currently for our mailboxes size it is currently at about 19gb and slowly growing. I dont think thats too bad considering we have it running for about 2 and half years. I just recently did the sp2 upgrade as we running standard and there was apparantly a limit on the size of mailboxes on standard, since the sp2 upgrade we can allow our mailboxes to grow no more than 80gb in size.
So I currently deciding on what I should do. I looking for a reliable, redundant/fault tolerant solution, would i better off having 1 fast exchange server with all mailboxes and separate groups for students and staff or separating this over 2 servers.
Is it possible to set 2 different security policies as well for two different mailbox groups? I would want to a more stricter policy for our students e.g. students cannot add attachments over 5mb,
Currently the server data is in a RAID 1 configuration and touch wood we have no problems with regards to performance, considering this server also does dhcp, dns, print server and DFS. I normally prefer RAID 5, would i be silly in changing this in the new configuration or shall i leave it on 1 bearing in mind performance is usually better on RAID 1.
Also if someone could suggest the the type of spec of server I would require if I had all mailboxes on 1 server, that would be most appreciated. I understand that Microsoft has a lot of this information on there web site, but on something like this I would value your opinion as well as you can never understand how the performance would be until someone has actually implemeneted this type of solution.
Also would I be advised on upgrading to 2007 rather than stick with 2003. I really love the benefits on the new OWA for 2007. If i brought a new server I was thinking maybe I use 2007, add all the students to this server, and then migrate all the staff from the old server onto the new server so all users are on 2007. Does anyone recommend this?
Your advice is much appreciated.
