主要调查结果
-- Iometer benchmarks peg full-duplex streaming I/O at 1,568MBps
-- VOE D2VTL backup application throughput for NetBackup measured at 1,350MBps
-- VOE D2D backup application throughput for VCB proxy process measured at 500MBps
Running full backups of eight VMs in parallel, our Windows-based HP server used the VCB driver to read a shared ESX datastore in order to copy VM snapshot files to a local directory. With the Brocade 815 HBA installed in our proxy server, we measured full- duplex throughput at roughly 500MBps. Using the Emulex LPe12000 HBA with the 5.2.20.6 Emulex driver, we consistently measured full-duplex throughput at around 360MBps.
When we backed up the VM backup image files, which were created in our first test, to a VTL with eight logical drives, the Brocade 815 HBA sustained full-duplex throughput os 1300MBps. In this process, we read data from the Emprise 5000 storage system at 650MBps and wrote backup images to the VTL at 650MBps in perfect balance.
