I have an EC2 Instance Windows Server Datacenter 2008, and I'm getting an "Unable to Activate Windows" message. Even after following through the instructions here
Client's DNS is managed by Office 365. Office 365 helpfully creates an SPF record:
TXT @ v=spf1 include:spf.protection.outlook.com -all 1 Hour
Even extra helpfully, this is automatically generated by Office 365 and can't be changed apparently. All I want to do is include Mandrill, but it looks like I'm SOL.
Apart from moving DNS management to another host (which would be painful, but doable), have I got any options?
I've got a total of 8 physical disks I can use (not including 2 for the mirrored OS) for a fairly high-use SQL Server.
It's used to serve a web-app (Win2k3, IIS6, ASP.Net) which has fairly heavy usage (400K users) with a fairly even proportion of writing and reading. However the database isn't very large (yet) - currently around 10G.
My initial thought is to split the database drives up in the following way:
- Hardware Raid-5 (3 discs) for Data
- Hardware Raid-5 (3 discs) for Logs
- Single disc for Tempdb
- Single disc for on-server backups
Essentially, I'm looking for the best performance by reducing disk contention between different writes (TempDB, Logs & Data).
I'd be curious to get any opinions of whether this appears to be the optimal set-up, or if you'd set up the disc layout differently.
We could spend another £5k for an external Raid setup to allow the Tempdb & backups to be RAID'ed as well, but I think it's a bit of overkill.
Any thoughts?
