  • 1.  ESX4 VM SCSI Controller Help

    Posted Jul 31, 2009 02:30 PM

    Hello All,

    Few questions reguarding the new choices for SCSI controllers in ESX 4

    1.) Which has the better perfomance LSI SAS or the new LSI VM controller

    2.) Which is better to use for settnig up a VM LSI SAS for all drives or LSI VM and use the IDE mode for the boot drive (Since the VM controller can't be used for a boot volume) and then use the VM controller for the rest of the drives)

    3.) Why is it that Windows Server 2008 shows the vmxnet2 or 3 nic driver and the LSI controller card as a removeable USB device ? is there no way to get rid of this?

    Ya it says to use the new PVSCSI for storage but your only allow to put one LSI controller in so would you put the one LSI controller in and put it in PVSCSI mode then when you create your boot disk set it to IDE? If you set it to SCSI it will go on the PVSCSI side and that is not bootable?

    Paravirtual SCSI (PVSCSI) adapters are high-performance storage adapters that can result in greater throughput and lower CPU utilization.

    o Best suited for high performance storage environments.

    o Not suited for DAS environments. VMware recommends that you create a primary adapter (LSI Logic by default) for use with a disk that

    will host the system software (boot disk) and a separate PVSCSI adapter for the disk that will store user data, such as a database.
