Where the Cloud Touches Down: Simplifying Data Center Infrastructure Management

Thursday, July 25, 2013
10:00 AM PT/1:00 PM ET

In most data centers, DCIM rests on a shaky foundation of manual record keeping and scattered documentation. OpManager replaces data center documentation with a single repository for data, QRCodes for asset tracking, accurate 3D mapping of asset locations, and a configuration management database (CMDB). In this webcast, sponsored by ManageEngine, you will see how a real-world datacenter mapping stored in racktables gets imported into OpManager, which then provides a 3D visualization of where assets actually are. You'll also see how the QR Code generator helps you make the link between real assets and the monitoring world, and how the layered CMDB provides a single point of view for all your configuration data.

How-To: Plan an iSCSI SAN

You finally got funding for your iSCSI SAN project. You convinced management that buying a new SCSI storage array with each new server cluster or purchasing one each time a server outgrew its internal storage cluttered up the data center and ate up the budget. Then you picked out the iSCSI arrays of your dreams and promised the powers that be that Ethernet is all you'd need to hook it all together.

Configure Your Network


Connect Your Server

Now comes the rude awakening. Just because you can run iSCSI across your existing network with your other traffic doesn't mean you should. Typical network applications are designed with the possibility of a network failure in mind, but operating systems expect their disk drives to be available all the time. An infected laptop that overloads your network for a few minutes could make servers that can't access their disks unhappy. So rule No. 1 in planning your iSCSI SAN is to place iSCSI traffic on its own VLAN and preferably on a completely separate, gigabit-speed network.
