Auspex NAS file server sets industry record at 19,755 IOPSSanta Clara 19 July 2001 Auspex Systems announced that its new NS3010 enterprise data server is processing up to 19,755 I/O operations per second in SPECsfs97 benchmark testing - more than 20 percent faster than the latest filers from its leading competitors. SPECsfs97 is an established standard for measuring Unix-based Network File Services (NFS) file server performance across different vendor platforms.
NFS file server throughput and response time for the Auspex NS3010 were
benchmarked at 19,755 IOPS in systems utilizing RAID 0 and 18,293 IOPS for RAID
5. The Auspex measurements reflect the performance of the NS3010 for a single
I/O node, the equivalent of a single server from other vendors.
A single Auspex system can expand up to three I/O nodes as workload increases in
order to provide scalability. Speeds in full three-node configuration are
expected to reach 46,900 IOPS when those systems are released later this year,
again outstripping competitive network storage appliances of comparable size.
For Unix-based applications involving transfer of extremely large files such
as seismic data, streaming media and supercomputer data sets, tests developed
internally at Auspex indicate a 12-client aggregate throughput for a 1GB file of
61 MB per second for sequential NFS reads and 70 MB per second for sequential
NFS writes. While there are no industry-standard benchmarks that permit direct
comparison, Auspex customers are reporting a noticeable speed advantage in
sequential I/O performance.
For Windows-based Common Internet File Services (CIFS), performance is
expected to equal or surpass competitive systems when Netbench/Diskmix benchmark
testing is completed in the third quarter. Kindred Healthcare, an early adopter,
has reported that the Auspex NS3010 is delivering Windows files 30 to 40 percent
faster than its previous data server.
For mixed NFS and CIFS environments in which both Unix and Windows files are
accessed simultaneously, internal Auspex tests on a one-node NS3010 system
indicate performance as high as 13,500 IOPS and 40 MB per second.
