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.

Software-Defined Storage (SDS): What Is It?

StorageNetworkingRecently, Nutanix got awarded a key patent for software-defined storage, and it got me thinking, “What is SDS?” Well, to me, one key aspect of SDS is the fact that it is hardware agnostic. Therefore, by default, Nutanix is not a provider of SDS. Now, don’t get me wrong: Nutanix is an awesome product and quite innovative in its offerings.

But, software-defined storage it is not. Hyperconverged? Yes.  Continue reading Software-Defined Storage (SDS): What Is It?

VSAN Pricing Comparison

Last week, VMware released vSphere 5.5 Update 1. You can find the release notes here, and the links to the download are here. Why is this such a milestone? It finally marks the release of VMware’s long-awaited entry into the world of software-defined storage, the VSAN (Virtual Storage Area Network). But before we move on to that, what else is contained in Update 1?   Continue reading VSAN Pricing Comparison

Will Scale-Out Architectures Kill Enterprise Storage?

StorageNetworking

In 1980 I was working for Datapoint, a vendor with proprietary client hardware, proprietary server hardware, a proprietary LAN, and proprietary systems software. In 1983 IBM introduced the PC, and in 1985 it introduced the PC-XT with a hard disk. 3Com introduced Ethernet, and Novell created a network operating system. All of a sudden, Datapoint was on the wrong side of history in the computer business. In five short years, Datapoint went from six thousand employees to sixty.  Continue reading Will Scale-Out Architectures Kill Enterprise Storage?

News: VMware VSAN GA Release Ships with vSphere 5.5 Update 1

VMware100x30After months of beta testing boasting 12,000+ beta testers, VMware has finally thrown its hat into the hyperconverged virtualization space with the GA release of VMware vSphere 5.5 Update 1. Among numerous bug fixes to vSphere, this release contains the GA code for VMware VSAN. VSAN is a shared-nothing clustered storage technology embedded in the vSphere hypervisor, ESXi, that uses collections of local, direct-attached host storage to provide reliable and high-performing storage to a vSphere cluster. It relies on both traditional rotating disk media and modern flash and solid-state drive (SSD) storage, forming clusters of up to 32 ESXi hosts over 1 Gbps or, preferably, 10 Gbps network connections.
