Network interface virtualization (NIV) is, in my opinion, a poorly understood technology that has a number of implications for network design and behavior. Here is some more information on NIV.
NPIV and NPV are both related to virtualizing some aspect of Fibre Channel N_Ports, but they are fundamentally different. This article provides some additional information on NPIV and NPV.
Here’s how to enable jumbo frames under both NX-OS 4.0 and NX-OS 4.1 on a Nexus 5000 series switch.
VMware, Cisco, and EMC made their official announcement of the VCE Coalition and the joint venture Acadia this morning. Acadia is interesting, but it really isnâ€™t the meat of the announcement, in my opinion. The real substance of the matter is the nature of the coalition.
Fibre Channel over Ethernet (FCoE) is receiving a great deal of attention in the media these days. Fortunately, setting up FCoE on a Nexus 5000 series switch from Cisco isnâ€™t too terribly complicated, so donâ€™t be too concerned about deploying FCoE in your datacenter (assuming it makes sense for your organization). Configuring FCoE basically consists of three major steps:
My last post about technology choices got derailed into a discussion about I/O virtualization technologies. So, I’m going to try again to get my point across about technology choices.
Every technology decision is a double-edged sword: vendors gain advantages and create disadvantages with their technology decisions. It’s important to evaluate technologies to discover both sides of the coin.
A question from a customer about NIC utilization and link aggregation prompted me to dig a bit deeper. Here’s some information I found on making sure you’re maximizing throughput on multiple links.
Much ado has been madeâ€”some of it by yours trulyâ€”about the current lack of ability to create a multi-hop Fibre Channel over Ethernet (FCoE) fabric. After digging in deeper with Cisco during my recent Unified Computing System (UCS) class, I have some additional information to share about the different forms of multi-hop FCoE and why multi-hop FCoE still isnâ€™t available.
I mentioned yesterday on Twitter that Iâ€™d had something of a revelation with regard to Fibre Channel over Ethernet (FCoE). This is probably nothing new to the experienced storage intelligentsia, but Iâ€™m just a simple guy so this was a big deal. After a spirited discussion in the Cisco UCS class about how to best leverage â€œFCoE-capableâ€ storage, I have come to this realization: there is no such thing as an end-to-end FCoE solution.
