Enterprise Storage Service (ESS)

DoIT's Enterprise Storage Service utilizes EMC Clariion CX700's. The CX700's are connected to servers housed on the DoIT platform through a Storage Area Network (SAN). They provide fiber channel disk storage to a variety of servers and operating systems including Windows, AIX, Solaris, and Linux.

Each CX700 contains 8GB of cache; can perform 200,000 IOPS; connect to 256 hosts; and can be expanded to hold up to 58TB of disk. At DoIT each CX700 is mirrored to a remote site to provide disaster recovery. All hosts are dual connected through redundant SANs, and each CX700 has redundant processors, making this a fast, reliable and economical disk solution for a wide variety of applications.

ESS service is currently available only to servers located on the DoIT Platform in the Computer Sciences Building on the Madison campus. Pricing information
