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.

Commvault Turns Snapshots Into 'Proper' Backups

March 21, 2011 09:00 AM
As we discussed a few weeks ago, you can certainly argue that snapshots, when combined with replication, could serve as an adequate backup system. My biggest objection was that snapshots lack the catalog that conventional backup applications build as they back up data. Commvault's SnapProtect fills that gap by providing catalogs and a management console for snapshots across a variety of arrays and other snapshot providers.

Can Cloud Snapshots Replace Backup?

February 24, 2011 09:00 AM
I'm satisfied that snapshots and replication in conventional storage systems can serve the same function as more traditional backup schemes. While snapshots make satisfying the most common restore requests easy the limitations of most storage system's snapshot mechanism leave most organizations using snapshots as a supplement to, not a replacement for, backup copies. Does the cloud change the snapshot as backup calculus? Some cloud storage vendors say it does.

Snapshots And Backups Part Deux

February 17, 2011 09:00 AM
In What Is A Backup?, I compared conventional backups to local snapshots, concluding that restoring data faster using backups is easier when you know where it was last. With conventional backups, an administrator, after cursing under his breath and wishing he could just say no to the CFO, could search the catalog database for *smith*.xls in Finance and locate the file. Since local snapshots don't include catalogs, it's harder to restore the data that disappeared sometime last summer. But there are more issues around using local snapshots for backup.

So, What Is A Backup?

February 15, 2011 12:00 PM
Last week EMC blogger Chuck Hollis started a bit of a firestorm when he questioned the marketing position some vendors are taking that local snapshots make traditional backups unnecessary. As we could expect, a series of EMC haters, employees of other vendors and industry analysts jumped in to add fuel to the fire. I think Hollis did ask a valid question: As technologies advance, what is a backup?

Recovering From RedoLog Corrupt Errors On VMware ESX/ESXi

RedoLog corrupt errors are a common issue on VMware ESX/ESXi machines where machines are snapshotted and the datastore is allowed to run low on space. Use this step by step guide to get your machine back in business.
