  • Replicating SAN to DR Site

    We are looking to build a warm DR site across town. How are other companies managing to duplicate their data in a reasonable time to another location? We are looking to copy around 150 GB per day. We don't need up to the minute data, up to the hour or two is acceptable.

  • 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
