Lab Gear Review: Synology DS212+

If you read my lab posts or talk to my about lab gear it’s no secret that I’m a fan of Synology NAS boxes and for good reason.  I personally bought two, a DS1010+ for my vSphere lab and a DS1511+ for lab, media, and home storage/backup.  They have both been nothing but reliable…true workhorses.

Who “owns” your Data Center?

More and more of our clients utilize third party data center facilities for production, disaster recovery, or both. With ever-increasing demands for power density, cooling capacity, and uptime / availability, this can often be the most cost-effective, future proof approach.
