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.

A Network Computing Webinar:
SDN First Steps

Thursday, August 8, 2013
11:00 AM PT / 2:00 PM ET

This webinar will help attendees understand the overall concept of SDN and its benefits, describe the different conceptual approaches to SDN, and examine the various technologies, both proprietary and open source, that are emerging. It will also help users decide whether SDN makes sense in their environment, and outline the first steps IT can take for testing SDN technologies.

A Great Decade For Tape

As I wrote about in my most recent entry, LTO-5 adds some capabilities that will lead to this being a great decade for tape. This time, the latest generation of LTO is bringing more to the table than just speed and capacity. LTFS, as we describe in our recent article "What is LTFS," is a great example of that. In fact, while capacity did see its normal upgrade in this generation, speed was only upgraded slightly. Fear not, speed upgrades will be back on track in generation 6. Holding LTO-5 back a little, but putting LTO-6 back on track, is a smart move by LTO.

Ever since LTO-2, and definitely since LTO-3, one of the biggest challenges has been designing a backup environment that can stream data to these tape drives. In fact, as I commented on Marc Crespi's blog "Is Disk With Deduplication Really Faster than LTO4 Tape for Backups?," one of the big advantages of disk is how forgiving it is of slow backup jobs. If you can get tape streaming, it is fast. The challenge is getting it streaming. Today this requires either a caching of backup jobs to disk first or a direct local backup.

If the LTO-5 spec would have done its normal doubling effect, I'm not sure how many data centers would have been able to take advantage of the performance boost. The advantage of slowing down on the performance numbers means the pricing of the drives should be less expensive. It is more economical to use the slower components.

When LTO-6 comes to market, we see a return to larger performance upgrades. This again makes sense. By the time we see LTO-6 come to market, much of the shift to either 10GbE or 8Gb FC should be well underway. Depending on how the timing works we may also see 16Gb FC by that point. We will have the infrastructure to move the data. Despite all the gains we are making in deduplication and compression technologies, the amount of data to be protected and the size of those components will continue to increase. In short, we will need that performance.

So where does disk as a backup target, the thing I normally write about, fit into all of this? We'll cover that in our next entry.
