• iSCSI SAN Server suggestions?

    We are in the process of purchasing a new SAN server. I was curious if anyone has any good or bad experience with HP, Netapp, Dell, Fujitsu or others. We will be using Exchange 2007 mostly in the environment and need something that is very expandable. Thanks

  • Accessing heterogeneous disk arrays to a Windows server using a single HBA via SAN

    I am planning my disk array upgrade, and I want to know if anyone has any thoughts, or if there are any reference/best practice/white papers, for accessing heterogeneous disk arrays to a Windows server using a single HBA via SAN. Any concern about the multi-path software?

    My current employer began allocating disk before having a storage administrator on staff. When a file system would achieve 90%, the individual systems admins would log on and just assign themselves new LUNs. This has made layout of the disk a nightmare. One thing they have done - in the name of...
