Two Dell EqualLogic 4100's. Both are loaded with OEM Dell Enterprise 600GB 10K SAS 6/gbs drives. Upgraded Type 14 Controllers, with 1 spare. The Type12 Controllers come with it as well. Upgraded the controllers for 10gb access for a proof of concept. Both units work well with no issues. The bottom controller had slight damage in shipping but does not affect operation, and all drives slide in and out. Can arrange shipping at buyers cost. Frieght would be approx 250 dollars. Selling everything in a group set. Make offer. Located in Charlotte, NC
