Breakthrough Performance with SVC 4.3 (SAN Volume Controller)
SPC-1 benchmark: Simulates I/O characteristics of OLTP workloads► SVC delivers up to 274,997 SPC-1 IOPS
SPC-2 benchmark: Simulates heavy sequential workloads► SVC delivers up to 7080 SPC-2 MB/s
SVC is the fastest storage virtualization system in both SPC benchmarks New SPC-1 benchmark obtained with Space-Efficient Virtual Disks
► Demonstrates SVC ability to deliver high performance and advanced storage provisioning capability
Measurements conducted using 8-node SVC configurations, 2145-8G4 nodes, and IBM DS4700 disk.For more information, see www.storageperformance.org/results
