Good post by Vladan Seget (thank you)

I somehow ignored this information but I think that it’s very useful to share, especially if you’re navigating the SMB or very SMB sector. In fact VMware VSAN for ROBO Two Node 10 GbE cross-connect support. So you have the possibility to cross connect ROBO nodes, via low cost 10GbE option and have a great performance because you’ll have dedicated VMkernel interface for VSAN traffic.

The Guide to Selecting Flash for Virtual Environments

Good post by George Crump (thank you)

High performance flash based storage has dramatically improved the storage infrastructure’s ability to respond to the demands of servers and the applications that count on it. Nowhere does this improvement have more potential than in the virtualized server environment. The performance benefits of flash are so great that it can be deployed indiscriminately and still performance gains can be seen. But doing so may not allow the environment to take full advantage of flash performance. It may also be a much more expensive deployment model and put data at risk. Modern data centers need to understand which forms of flash and which deployment models will show the greatest return on investment while not risking any data.

Why the FCoE vs iSCSI Debate Continues

Post by Jeff Asher (thank you)

A LOOK BACK AT FCoE and iSCSI HISTORY — There are two entrenched standards for block storage protocols over Ethernet networks. FCoE was ratified in 2009, while iSCSI was ratified in 2004. Of course, various vendors and early adopters supported these protocols before ratification, so the history of these protocols is a couple of years longer than it looks, respectively. While iSCSI simply encapsulates the SCSI protocol in IP, FCoE operates lower in the network stack and to do so required many enhancements to Ethernet. While iSCSI runs on any IP network (mostly Ethernet these days), FCoE requires Data Center Bridging and Converged Network Adapters all running at 10 Gbps or faster.

IBM XIV Storage Systems Gen3 Model 214 support for Capacity on Demand feature for systems with 10GbE interface modules

Information

IBM® XIV® Storage System Model 214 for machine types 2810 and 2812 supports Capacity on Demand (CoD) feature activation for systems equipped with 10GbE interface modules for 2 TB and 3 TB drives.

XIV Storage System Gen3 Model 214 with IBM XIV Storage System software version 11.2.0, or later, installed.

Intermixing of port bandwidth between 10GbE and 1Gb within the same system is not supported (mutually exclusive).

Partially populated IBM XIV Storage Systems that are shipped from the factory with any of the raw capacity per drive options must continue to be populated with the same raw capacity per drive option.

Intermixing of 1 TB, 2 TB, or 3 TB capacity options in a single XIV Storage System frame is not allowed.
