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.

Why Flash Storage Excels In Virtual Environments


All-flash systems do more than replace a lot of hard drives. They let you create extremely dense virtual server environments that eliminate physical server hosts.

When we suggest that a company consider an all-flash storage system to solve a performance problem, there is almost always resistance to the cost. That is a fair concern -- it's common knowledge that flash storage is more expensive than hard disk storage. But this is only true when compared device to device. When they compare the cost against the full benefit of the system, we have seen many data centers become believers and actually save money by going with a flash appliance.

The first thing to realize is that few if any flash array or flash appliance vendors really expect you to replace all of your storage with flash. And as we will discuss in our upcoming webinar, "SSD on a Budget," when used to augment existing storage, an all-flash system can be had for well under $100,000.

Many all-flash vendors will try to steer the conversation away from cost per GB to cost per input/output operations per second (IOP) -- a good strategy for vendors given the tremendous advantage that flash systems have in IOPS. If you have an application, such as a database, that is specifically IOPS constrained then this might catch your attention.

The traditional way of dealing with a storage performance problem is to create very high-drive-count arrays. The challenge with this approach, of course, is the sheer cost of deploying 100-plus hard drives to generate the right amount of performance. In addition, many data centers will only format the outer edges of those drives to make sure that data is landing on the fastest portion of the drive. This technique obviously wastes even more capacity and consumes even more power and budget dollars.
