Storage Networking

Storage Networking focuses upon virtualizing the storage and the SAN while collapsing and simplifying the management and performance of storage. This includes the role of storage virtualization in the Software Defined Data Center, and the comparison of pooled local storage options with traditional network attached storage (NAS) and fiber channel attached storage. Covered vendors include VMware, EMC, IBM, Dell, HP, Cisco, Tintri, and Nutanix.

VDI, a Beauty & a Beast: A Nutanix Story

DesktopVirtualizationRecently, I wrote an article about what Citrix has done around virtualizing GPUs and GPU sharing, based on a podcast with Derek Thorslund, director of product management for HDX at Citrix. When the story hit the social media sphere, I got clobbered with hits about Nutanix and its partnership with Citrix and NVIDIA, along with a handful of requests to lead a podcast and write about its involvement with the GRID vGPU tech in its virtual desktop infrastructure  (VDI) business. So, just for the folks who reached out, here is my response.  Continue reading VDI, a Beauty & a Beast: A Nutanix Story

Dell Fluid Cache for SAN

Back in mid-2011, Dell acquired RNA Networks, a small startup out of Portland, Oregon. At the time Dell purchased it, RNA had a product, MVX, that employed three different ways to pool memory across multiple servers in order to accelerate workloads. One was a way to pool memory as a storage cache in order to speed disk accesses using system RAM. In the spring of 2013, we saw some of these features emerge again as Dell’s Fluid Cache for DAS (direct-attach storage) morphed to use the incredible speed of PCIe-based SSDs instead of RAM. Now, in late 2013 at Dell World, we finally get what many of us have been waiting for: the announcement of the expected availability of Dell Fluid Cache for SAN.

Replacing Franken-Monitors and Frameworks with the Splunk Ecosystem

Franken-MonitorsmallIn Beware of the Franken-Monitor, we explained how many enterprises ended up with Franken-Monitors and the dangers associated with assuming that the present state of management tools can make the transition into the software-defined data center (SDDC) and the cloud. In Getting Rid of Your Franken-Monitor, we explained how to use green-field islands to put in place new ecosystem-based management stacks with the intent of eventually retiring your legacy management stacks. In this post, we detail how one could deploy one example of such an ecosystem of tools based upon Splunk and the vendors that comprise its ecosystem.

Beware of the Franken-Monitor

Franken-MonitorsmallTen years ago, legacy management software vendors were busy building Franken-Monitors. Those Franken-Monitors now consist of legacy management offerings that are neither well integrated, nor in any way able to keep up with pace of innovation in the industry. In order to survive your transition to the software-defined data center and the cloud, you will need a management software strategy and a management software architecture that will allow you to keep up with the pace of change without buying or building a Franken-Monitor.

Are Market Dynamics Going to Kill IBM?

DataCenterVirtualizationOn October 17, the Wall Street Journal reported that IBM revenues have now declined for six straight quarters. IBM has told financial analysts that the company is capable of generating revenue growth in the low to mid single digits, but the fact is that IBM has not achieved that kind of growth since 2011. According to the report, IBM’s hardware revenue has fallen by 17%, with the hardware unit losing $167M, and the growth in the software business has gone from 4% to -1% (in other words, the software business has shrunk).
