After months of planning and waiting (and years of grant writing and more planning and waiting), my dev team, blitZEN (and our constituent research centers at the UNC School of Medicine: CCBC and PaTRC [no link yet!]) have now procured, (mostly) configured and racked the first wave of our enterprise hardware stack.
Ain’t it purdy? Check out this gratuitous drive array shot:
I need to prod the responsible folks to discuss all of the gory details (I didn’t have any input in engineering this but boy I had lots of input-ing them in the damn rack! ;) ), but here’s what we’ve got hardware-wise:
I will verify/update this for accuracy. This is off the cuff, strictly from memory
- 4 1-U Silicon Mechanics servers. Dual Quad-core (Intel processors I believe). Right now they’re allocated 2 for production web use (you may notice the gap, one konked out on us before we could rack it, we’re currently waiting for a replacement), 1 for development, and 1 for file sharing (SAMBA) and staging.
- 2 CORAID AOE cabinets. 48 drive slots all filled with 1TB hard drives. (that will equate to something like 45 TB of RAIDed storage)
- 1 CORAID EtherDrive hardware virtualizer. We can slice up those 45TB into logical volumes that can be resized at will.
- 1 HP Procurve switch for a private SAN network (that’s why it says “NON-ROUTED” on it :) )
- Public and private inter-box communications handled by our gracious hosts (campus networking services)
In case you’re wondering, we’re going to use the web servers predominately for Plone sites, and the AOE storage for Data.fs storage and windows file sharing of research data. We’re expecting large Data.fs files since we’ll be doing a lot of storage of data directly in Plone too. We may offload to the SAN for file storage in Plone, but we’re not sure just yet. There’s a definite need for some of Plone’s key features for the files in question (versioning, security, etc), and we have to make sure those will work the same with something like FileSystemStorage. We plan to eventually attempt in sillico experiments, crunching the data stored via Plone.
SO, the first ever blitZEN racking day is over, and it was a huge success. Special thanks goes out to ITS for making this possible.
