Okay, we all want to be and produce life-long learners, but sometimes being a life-long learner is hard work.
For example, the goal posts of K12 technology keep moving. What used to be “good enough” changes every two years or so. In the old days, having a good quality file server was fine, and a moderate to low range backup tape drive. A while later, a good quality NAS File Server was needed, with a Tape jukebox arrangement. Then some online backup was needed. Now, today, we just finished installing an HP NAS pair of Fileservers, that back up to a SAN system distributed to two server rooms in the building, and we still need to run about 5 TB to tape occasionally. That, and we need a cross-town extention of the SAN system. In the future, we might need redundant servers across two, or 50 miles away, that can pick up in case of a local failure.
Details: we went with two HP DL185 Storage Servers (9TB raw each) formatted to RAID 5 (ending up with 6.1 TB each). One unit is for Fac/Staff and Department shares. The other is for Student and Course folders. Both back up to a pair of HP Lefthand SAN units (12 TB raw each) formatted to RAID Five (drops to around 8.5 TB each), but the pair will be separated across the building and work as a single cluster unit.
We also just replaced our Cisco network core, and are implementing a Zimbra email system, but I’ll cover those in the next posts.
