Several years ago I was working at a company that had a ton of legacy silo applications that collectively represented the entire process flow that supported the core business. The process flow was made up of years and years of legacy technologies and legacy business processes. Continue reading Lessons Learned from Transforming a Company
Since the turn of the century, virtualization and cloud computing have become two of the most important areas of technological advance. Now that the technology has matured, as well as become mainstream, have you ever stopped to ponder the question of which part of the business market appears to benefit the most from the cloud? Continue reading What Parts of the Market Appear to Benefit the Most from the Cloud?
VMware announced its intention to purchase Desktop-as-a-Service vendor Desktone at this year’s VMworld in Barcelona. The first strategic purchase by VMware’s EVP and General Manager of End-User Computing, Sanjay Poonen, Desktone finally sets the stage for VMware to bring to market its first defined cloud service. Continue reading VMware Buys Desktone and Adds Desktop-as-a-Service
Everybody in IT knows by now that flash memory is redefining the enterprise storage industry, mostly by decoupling performance from capacity. Most storage vendors are happy to just add flash to their existing product lines, often using it as cache, or as a storage tier handled transparently within the array. Few vendors take the opportunity to rethink the way storage works, though, from the basics of performance to how it meshes with the idea of public & private clouds. Coho Data, coming out of stealth mode with their first product, the DataStream, does just that. Continue reading Coho Data DataStream
In the world of virtualization storage it seems all we talk about lately is flash and SSD. There is a good reason for that. Traditionally, storage capacity and storage performance were directly linked. Sure, you could choose different disk capacities, but in general you needed to add capacity in order to add performance because each disk, each “spindle” could only support a certain number of I/Os per second, or IOPS. This was governed by the mechanical nature of the drives themselves, which had to wait for the seek arm to move to a different place on disk, wait for the seek arm to stop vibrating from the move, wait for the desired sector to rotate underneath the read head, etc. There’s only so much of that type of activity that can be done in a second, and in order to do more of it you needed to add more drives. Of course that has drawbacks, like increased power draw, more parts so more chance of failure, and increased licensing costs since many storage vendors charged based on capacity.
Flash memory takes most of what we know about the physics of storage and throws it away. Because there are no moving parts, the act of seeking on a solid state disk is a completely logical one. There are no heads, no sectors, no rotation speeds. It’s all the speed of light and however fast the controller can go. As such, flash memory can do enormous numbers of IOPS, and if implemented well, it decouples storage performance from storage capacity. You save power, you save data center space, you save money in licensing fees, and your workloads run faster. Continue reading SanDisk FlashSoft for VMware vSphere
In Management Frameworks Will Die we make the case that frameworks have failed because no one product can monitor everything, because management frameworks cannot be modernized to meet the needs of the Software Defined Data Center and the Cloud, because frameworks are too painful and expensive to maintain, and because customers prefer the “try it before you buy it” model of buying management software to the enterprise license agreement approach favored by the framework vendors. Continue reading What is Going to Replace the Legacy Management Frameworks?
