1 Comment SANbox - 02/10/10

 

Picture of my custom Case

Each power supply powers one of the mainboards, and two of the fans (1 in/1 out).  Prior to putting the door on the case I’m going to add a shroud onto each of the IN fans, to direct air onto the motherboards.

I mounted the boards so that all of the connectors are facing forward for ease of access.

The systems will be direct connected by a Fiber connection and a copper connection.  The fiber connection will be through the Qlogic HBA that will be running a driver with TCP support for the DRBD replication.  The copper connection will be an additional ring for the cluster stack to communicate.

Each system will also have a fiber and copper connection that leaves the box and plugs into the appropriate switch.

I haven’t decided how I’m going to install the base storage of 4 disks (with plans to expand to 8 soon).  I’d like to have them in the case, but I’m concerned things might get to crowded – so I may build a small box and run them external.  I just have to make sure the SATA runs stay less than 1m.

Here’s a picture of the case I’ve built to house the computing end of my home SAN.  The lower two fans pull air into the case, the upper fans pull air out.

Comment How-to: Delayed - 02/2/10

There will be a day or two delay until the next part of the how-to – last night I cooked my test setup, so I am rebuilding it and trying to figure out what I did wrong.

The next installment will cover configuring DRBD in an dual-primary configuration, monitored by pacemaker.

ETA: Thursday
