IBM EXP3000. Total installed storage capacity: 12 TB, Storage drive capacity: 1000 GB, Storage drive size: 3.5". Power supply unit (PSU) capacity: 515 W. Dimensions (WxDxH): 447 x 550 x 87 mm, Power requirements: 115 – 230 V AC/ 48 V DC, Power management: AC & DCThe IBM System Storage™ EXP3000 Express is a high-density 2U, 19" rack mount driven closure designed for supporting a total of twelve 3.5" disk drives. IBM System x Server AttachmentRobust and flexible, the EXP3000 Express can be used as a direct-attach solution for IBM System x servers with support of MegaRAID or ServeRAID host bus adapters. Multiple EXP3000s can be connected to expand capacity and to help address your data needs today and tomorrow. Solid state drives present an opportunity to simplify local storage infrastructure to help maintain overall maintenance and cooling cost, while considering remote storage solutions for end-to-end data availability as part of their System x ecosystem. Solid state drives are an appropriate solution for local OS booting, high performance input/output applications, and some local storage space. Increasingly, solid state storage may be a practical component in balancing datacenter cost, reliability, and manageability.
