CARLSBAD, CA -- Dot Hill Systems Corp. (NYSE:HIL), a leading supplier of carrier-class data storage and storage area network (SAN) solutions, today announced the results of benchmark testing of its SANnet(TM) 7100 Fibre Channel storage system. CASPUR, southern Italy's premier non-profit scientific research consortium, benchmarked the SANnet 7110, which confirmed SANnet to be a viable building block for distributed storage solutions in the IBM SP3 environment. Over the past few years, CASPUR has built a heterogeneous SAN that began with Dot Hill's legacy LynxArray II and currently includes SANnet 4200 and 7100 systems along with Brocade switches. A variety of operating systems including Solaris, AIX, Linux and Windows are running on the servers connected to the SAN along with Fibre Channel tape libraries for backup. Because CASPUR is an inter-university research consortium, interoperability and open standards are a must. With the proven performance and interoperability of the existing SANnet-based SAN, CASPUR's lead systems engineer, Andrei Maslennikov, decided to investigate the possibility of configuring a fast, high capacity, redundant storage solution on CASPUR's IBM SP3 four-node frame. Maslennikov said, "The obvious choice for this architecture was the IBM serial disk system, but because Dot Hill's SANnet has performed so well I wanted to run a benchmark performance test. The test proved that SANnet is fully compatible with the IBM SP3 and performs as well as the SSA (serial storage architecture) disks in this environment. Furthermore, the total cost of ownership is lower because of SANnet's open systems architecture versus the proprietary SSA disks." The benchmark test was conducted with four SANnet 7110 RAID (redundant array of independent disks) systems and large (1 to 32 gigabyte) files in a buffered and unbuffered write speed test. SANnet's performance corresponded very well to measurements recorded by Lawrence Livermore Labs with SSA disks. For more information visit www.dothill.com
