vmware ESX4 + Emulex FC HBA + HP Storageworks EVA 8000 + linux operating system: low performance???
Posted on 2010-09-10
We currently use the following configuration:
- ESX4 hosts on DELL R710 / DELL R900
- Emulex LP1050 FC cards
- HP Storageworks EVA 8000 2C2D configuration, incl. 24*300 GB FC-SCSI 10krpm discs
- Debian GNU/Linux 64 bit operating systems as guests
And, we discovered, some times the i/o of linux hosts are so slow, means 1Mbyte/sec! It seems, the storage is working well, no high loads detected.
