Interop NYC and The Great Debate: ISCSI Beats Fibre Channel

iSCSI is the challenger for long-dominant Fibre Channel protocol SAN

The battle lines are drawn between 8 Gb Fibre Channel and 1 Gb or 10 Gb iSCSI and NFS. This is the baseline for my Interop debate. I am not arguing about the future of SAN, or even iSCSI versus NFS. Rather, I am arguing that most businesses would be best served by implementing an iSCSI SAN rather than purchasing Fibre Channel today.

Storage Changes in VMware vSphere 5

VMware mucked with vSphere licensing again...

Once again, VMware added a ton of new storage enhancements to vSphere. With storage rapidly becoming the limiting factor in scalability and performance of virtual machine environments, this is no surprise. Also not surprising is the fact that major features like Policy-Driven Storage and Storage DRS (along with SIOC) are exclusive to “Enterprise Plus” licenses.

Three Key Storage Features Missing in Mac OS X “Lion”

Mac OS X 10.7 "Lion" lacks many of the storage features we've long hoped for, including ZFS, iSCSI, and USB 3.0

Apple is not in enterprise storage company to be sure, and news from WWDC dashes any hopes we had for ZFS and iSCSI support. USB 3.0 seems a foregone conclusion, but Apple seems intent on ignoring it as long as possible. Although I welcome the new storage features included in Lion, it is disappointing that these were left out.

FCoE vs. iSCSI – Making the Choice

iSCSI is an excellent choice in situations where Fibre Channel investment is nonexistent or badly in need of wholesale upgrade, while FCoE is likely to take over in high-end enterprise shops

iSCSI is an excellent choice in situations where Fibre Channel investment is nonexistent or badly in need of wholesale upgrade. FCoE, on the other hand, is likely to take over in high-end enterprise shops. It is relentlessly promoted by major vendors, and it seems that they will force the upgrade eventually.

Iomega StorCenter PX Series Preview

The Iomega StorCenter PX4 is both an evolution of the IX4 and the start of a new line

The StorCenter PX line is a major step forward for Iomega. The BYOD option is welcome, as is SSD performance and improved specs. With official Citrix XenServer, Microsoft Windows Server, and VMware ESX support, the PX is finally up to the task of business computing. We look forward to putting these new devices through their paces in the future!

Changes in Technology Drive Changes in IT Organizations and Roles

Servers, storage, and networks may be interconnected, but most large IT organizations keep the administrative teams from mixing. But the next-generation virtual data center might change that!

Lots of my IT infrastructure management clients are talking about how the advent of Ethernet/IP and virtualization is changing the roles of storage, server, and network administrators. The evolution of the storage role in particular in enterprise IT organizations has been a topic of particular interest to me for a while: I definitely remember thinking about [...]

Back From the Pile: Interesting Links, April 8, 2011

This regular series features highlights from the week. Read my thoughts concerning HDS following their “blogger day” in London. Also, my good friend W. Curtis Preston announced more Backup Central Live! dates; you really ought to go see him!

Here are my shared links from the first half of the week, featuring more Apple stuff along with storage, virtualization, and a storage gorilla!

The Lure of Layer 2

"Bridging versus routing" brings us to the perennial networking debate: Are low-level protocols better?

Unless you’re “in the know”, terms like “layer 2″ can seem mysterious, making it all the more plausible when someone touts the benefits. It seems logical: “Bare-metal” communication must be better, faster, and cheaper than higher-level “everything over IP” approaches, right? But it’s not quite that simple.

Why Do I Ignore NAS?

Why does network-attached storage (NAS) have such a poor reputation? This isn’t what the vendors want to be talking about, but some recent product announcements and discussions led to this thought. IT folks as a whole don’t trust NAS for real work, and 20 years of effort from big names like Sun, Microsoft, NetApp, IBM, and the rest hasn’t changed that.
