| + | * **June 18, 2012**: | ||
| + | * Had a meeting with Ian Moore and Isaac Kahugu about storage | ||
| + | * He said he'd support us building our own, but gave us tips to talk to Tor at ICRAF (GIS, MySQL, Drobo), and to consider Dell Equalogic for storage | ||
| + | * Another point was that we could possibly buy storage from KENET (to sync off site), or maybe colocate a box there | ||
| + | * **July 10, 2012**: | ||
| + | * GK from Techno Associates called again with a new offer for a single-site, | ||
| + | * He said he can give us 12TB raw for $9,000, or 24TB for $11,000 (one controller only, excludes pricing for replication licenses) | ||
| + | * **July 22, 2012**: | ||
| + | * Begin compiling report about current situation, options, and recommendations | ||

| + | * **July 23, 2012**: | ||
| + | * George Ogoti provided us with an iSCSI target on their NetApp so we can test configuration and performance, | ||
