State University Selects Solid State SCSI Disk Technology from BiTMICRO to
Accelerate Access to User Information
|Editor:- August 18, 2004 - BiTMICRO Networks
today announced at HP World 2004 the successful integration of its
E-Disk solid state flash disk drive within Utah State University's
enterprise e-mail application.
Utah State University maintains a VMS cluster composed of four
machines. Used as a central computing resource by administrative and academic
users within the university's data network, the cluster is powered by OpenVMS,
an advanced operating system that operates on the VAX and Alpha architectures.
Data storage is provided by an HP StorageWorks Modular Smart Array 1000, a 2 Gb
Fibre Channel to Ultra SCSI storage system for entry-level to midrange SAN
The VMS Cluster is utilized by almost 25,000 users, composed
of students, faculty and administrative personnel of Utah State, to access their
email accounts. Due to the growing number of online users, users started to
notice degradation in response time. Utah State looked around for a solution and
decided to install a 3.5" E-Disk SCSI Wide flash disk to the HP MSA1000.
After the installation, users immediately noticed a significant
improvement in access time. It plugged in directly just like a regular hard
disk drive and was recognized and configured just as easily.
"We looked around for a suitable storage solution and found few
that fit into our existing IT infrastructure. Our tests show that the E-Disk
offered speeds four times faster than an older RAM disk and about 15x
faster than magnetic disk drives. Speed and cost are our primary concerns, and
we're happy to note that BiTMICRO's E-Disk flash drive is a worthwhile
investment given its outstanding performance," states Kim Marshall,
Director, Network and Computing Services of Utah State.
