The cache hit rate depends highly on the application running against the DB. If you control the application, you should be able to get a very high hit rate. If you don't, (and it is poorly written), you can expect some really low values.

comment Lync Server 2010 with Hosted VoIP PBX
Quite a few SIP providers support E911 which pass extra information per DID. Assuming your remote works get their own DID, you can get it going that way. In our setup, we map the users desk phone to their E911, and their home phone sends out the same callerid. The other users are handled by an in-between service which answers the called before 911 one gets it. It however is something like 50USD per call.

comment Failover Cluster : Microsoft Exchange Server 2010
You can get around the shared storage requirement by doing the CAS array and having 1 node on each server, then use the DAG across the two servers. The hardware load balancer isn't totally necessary when using NLB on the hosts, just watch for all the broadcast traffic on the vlan.

comment High Availability DNS Hosting Strategy?
If you can get your existing provider to enable XFER transfers, the new host can copy the entire DNS zone in a single command. Then it is just a case of swapping the name servers.

comment Correct way to set up DNS primary/secondary/… for redundancy and latency reduction?
The default linux config doesn't cache down'd nameservers. This applies also to a few linux based appliances (such as our IP phones), which means that when the primary goes down, the dns queries take so long because every query tries the primary, waits 5 seconds, then tries the secondary, that things basically stop working under load.

comment Correct way to set up DNS primary/secondary/… for redundancy and latency reduction?
Most linux clients default to a 5 second timeout which is a killer. Second DNS server or not, once the primary is down, it'll be so slow, it'll appear down.

comment Avoiding DNS timeouts when a dns server fails
What happens when your production hours are 24x7? DNS should fail to the second/third/x server AND cache the failure of the other server for a period. The Default 5 second timeout is enough to bring services down depending on the load.

comment Is there a Linux utility that can distribute files to an array of hard disks, like a load balancer, but for storage?
Raiding file systems across remote systems already exists. On large scale you have GFS (and quite a few other proprietary ones). Coda is a smaller scale on which would properly work, but for this why would you bother?

comment Exchange 2007 Message Queueing Times and Limits
Further to this, you won't be able to tell how many customers got bounce backs, and nothing on your side will help as you don't control the settings on a customer site. Having a backup MX is cheap these days and most ISPs or webhosts offer the service.
