Meeting with the electrician tomorrow morning for a quote on power for the server room. Tips?

We are looking into the possibility of using a small yet air conditioned closet as a temporary (hopefully no more than 5 years) server room.

We definitely need a more central/larger/ideal room for a permanent location, but this room will be a huge step up on cooling and isolation. (servers are currently in a shared storage room with nearly non-existant cooling)

The current setup does work, so I think we should be okay as long as we can start with what we have now plus an additional 30 amp circuit. Also looking to put a single patch bay in for the whole floor and run 4 x 1Gb Cat 6 trunked between the new room and the primary wiring closet. (until we can afford home-runs of fiber to each wiring closet around campus)

Feel free to comment with advice/warnings/free coffee.

I hear the child check in system test went great tonight!

The child check in system we are implementing at Calvary of Albuquerque is a custom written system that involves a central server, several check-in kiosks, and a touchscreen display in each classroom.

Labels are only printed for visitors, people who lost/forgot their badges, and parent volunteers. The "regulars" just use their plastic bar-coded badges for check in.

Overall it is a very slick system, and TCO is still about the same as a year of service from a few of the vendors we were looking at before. (the other vendors looked great, we just had a few special needs we wanted met)

Awesome job team!

Backup server almost ready for testing!

I subscribe to Alex Lindsay's school of thought that claims data doesn't exist until it exists in two places. Unfortunately that costs money.

We have about 3TB of user data and 4TB of current videos.  (We will be expanding the video library to 10TB soon I hope.)

Before we can implement a full backup solution, I'd like to duplicate our data.  When talking about this volume of data you have two options: do it right or do it cheap.  We're going to do it cheap! (remember, this is phase 1 and our goal is having data in two places)

The correct way would involve a proper backup SAN, tape backup system with off-site storage, and a bit of could based backup just in case.

The cheap way involves any system that lets me buy off-the-shelf SATA drives and keeps track of file versions.

Here's the Phase 1 setup:

  • desktop computer
  • 2 extra Intel gigabit NICs
  • Drobo Pro
  • 4 x 2TB SATA drives
  • Crashplan Pro Server
Total cost comes to less than $4,000 which isn't bad for 5TB of iSCSI backup storage that does file versioning and deduplication.  Now I just need to invest another $600 for 3TB more of usable backup storage.  (caveat: single iSCSI nic, single RAID controller, single power supply... the backup is not redundant, only the live data on our MD3000i is)

The next step will be to migrate all of our physical servers to virtual servers and use Veeam to do live deduplicated backups to the same drobo pro.  Then I'm sure there's some way we could set up a simple robocopy script to mirror our entire backup system to another set of drives that get pushed to our colocated server rack downtown.

We will also be looking into cloud-based backups for critical databases and files.
