I'm in the process of upgrading an old server that utilized non-server hardware (P4, RAID1 with PATA, 1GB RAM ). This runs W2k03 R2 x86 with no active directory; it currently currently provides roles for file sharing access and SQL access for 15 users. Once decomissioned, the old server will be used purely as an SQL server with updated RAM hard drives.
Users complain of slow access (opening Work or Excel files can take up to a minute); database access is also very slow. The network currently runs over 100Mb/s hardware, and is also being analyzed.
I ran perfmon on the server for a few days, and noticed that the memory was definitely lacking (constant paging). The processor utilization never crept above 70%, and only peaked there a few times. Hard disk access was at 100% for roughly 20% of the time. A memory and hard disk I/O upgrade are due.
The CEO would like to move to active directory, for centralized management, security, etc. We will also be adding an Exchange server to our network.
Our budget is 10k max (includes hardware costs, OS/Exchange costs,etc.); curious as to some views on recommended server setups.
Requirements for the file server include using SAS in RAID10, so much of the hardware budget goes there.
From my calculations, software and licensing costs run around $3700 alone; that leaves $6300 for servers. I'm thinking of utilizing only (2) servers, and sharing (2) of the titled roles on (1) server. Is there a better than not recommendation when deciding which of the two roles to combine?
Should I shoot for a very low cost Poweredge for the domain controller, as that will not be largely resource intensive (anyways, I'd rather have (2) low cost domain controllers, than (1) high-end one; then I can put the rest of the budget to a more powerful Poweredge for an Exchange/File Server combination?
SATA 7200 in RAID1
2x Quad Core Xeon
8 x SAS 10K in RAID10
Both servers would have redundant power supplies, Intel NIC's, and DRAC.
