I already bought a phisical raid card.
Name: LSI SAS3041E SAS S-ATA 3GBit RAID Controller PCI-e
Prop.: LSI Logic 3041E-R PCI-e 3Gb/s, SAS/SATA 4-port Host Bus Adapter RAID 0, 1, 1E,10E Processzor LSISAS1064E Internal JBOD enclosures Mixed SAS/SATA RAID n 140,000 I/Os
I have 2 1 tb SATA disk.
If i use this raid card the vmware on the install see the raid array but with this card the esxi 5.1 / 5.0 very slow! Example one operation without this raid card 4 min with this raid card 40 min. I think its not normal.
