comment Latency & SQL Connections over Fiber WAN - Application E-manage
Blaming virtualization is the low-hanging fruit of buck passing these days. If I had to guess I'd say that your software makes many small queries instead of a few large queries. When the latency between application and DB is <5ms the overhead is not a problem, but once you bump that up to 45ms RTT users might notice some lag. You can try replicating a copy of the app DB to the remote office, but that will present its own challenges as you're not likely going to be able to write to the slave and who knows if this app will handle multi-master replication.

comment mysql swap file crash on freebsd
1. There's a scheduled task somewhere. 2. You can't, your system ran out of memory and it's in an unstable state at best. Reboot. 3. Maybe you should get more RAM added to your VPS.

comment Cannot connect to MS services across networks
You win the prize. While I was properly checking that Windows firewall was disabled, I was completely ignoring Kaspersky's firewall. Turns out there are some 'Trusted Network' settings in Security Center that I've been ignorant of for the past two years. :I

comment can I keep company-purchased IP addresses when migrating to AWS (or other hosted service)
You should ask an/your amazon rep, not internet randos. If you've actually purchased the block from your RIR [eg: ARIN] they might be able to accommodate you. If you're leasing from your ISP, it's very unlikely.

comment What is RAID 5 write logic with 8 drives running SQL 2008?
@Alex literally your only hope is that they can bring one of the dead drives back to life and get the array to hobble along for long enough to pull the critical data. Sure they can get "data" off of the 6 remaining disks, but none of it will be useful since 1/7th of each file will likely be missing. Repeat after me: "RAID is not, and never was, a backup. I will slavishly monitor my array health from now on so dead disks do not go un-noticed."

@Alex you are hosed, your data is unrecoverable. Your data is ground beef and you're asking someone to reconstruct the cow.
