Some EMC Product Updates

There have been a few important EMC product updates over the last few days that I thought I might highlight here real quick:

FCoE through a Nexus to a MDS-Attached Storage Array

In this post, I want to pull together all the steps necessary to take a Converged Network Adapter (CNA)-equipped server and connect it, using FCoE, to a Fibre Channel-attached storage array. There isn’t a whole lot of “net new” information in this post, but rather I’m summarizing previous posts, organizing the information, and showing how these steps relate to each other. I hope that this helps someone understand the “big picture” of how FCoE and Fibre Channel relate to each other and how they interoperate (which, quite frankly, is one of the key factors for the adoption of FCoE).

Allegations Regarding FBI Involvement with OpenBSD

Let’s get right to the point and set the record straight: I am not, nor have I ever been, affiliated with or employed by the FBI or any other government agency.

A Quick Review of VPLEX Storage Objects

Now that I’ve managed to get my VPLEX clusters up and running, I’m ready to start providing some posts on VPLEX and how it’s configured and used. To get things started, I want to first provide an overview of VPLEX storage objects and how they relate to each other.

Using Device Aliases on a Cisco MDS

As a follow up to a few posts I published last year on using the CLI to configure and manage Cisco MDS Fibre Channel zones, here is information on using device aliases. (Read more...)

VLAN Trunking Between Nexus 5010 and Dell PowerConnect Switches

If you don’t work in the networking space on a regular basis, it’s easy to overlook interoperability issues between equipment from different vendors. After all, a VLAN trunk is a VLAN trunk is a VLAN trunk, right? Alas, the answer is not always quite so simple.

Connecting a Nexus 2148 to a Nexus 5010

The Cisco Nexus 2000 series fabric extender (or “fex”) is an implementation of network interface virtualization. Because the Nexus 2000 fabric extender acts as a remote line card to the upstream IV-capable bridge (a Nexus 5000 series switch, typically), all the configuration takes place on the upstream bridge. In this post, I’ll describe how to connect a Nexus 2148T to a Nexus 5010. In reality, the process is incredibly simple and not really worthy of a blog post, but in the interest of completeness I’ll document it here.

SAN Port Channels from Nexus 5010 to MDS 9134

As part of an ongoing effort to expand the functionality of the vSpecialist lab in the EMC RTP facility, we recently added a pair of Cisco MDS 9134 Fibre Channel switches. These Fibre Channel switches are connected to a pair of Cisco Nexus 5010 switches, which handle Unified Fabric connections from a collection of CNA-equipped servers. To connect the Nexus switches to the MDS switches, we used SAN port channels to bond multiple Fibre Channel interfaces together for both redundancy and increased aggregate throughput. Here is how to configure SAN port channels to connect a Cisco Nexus switch to a Cisco MDS switch.

Technology Short Take #7

Welcome to Technology Short Take #7! This time around I have a collection of links from networking, servers, storage, and virtualization. Our hot topics in this issue include Fibre Channel over Ethernet (FCoE) and its need—or lack thereof—for congestion management, Ubuntu on Hyper-V, the benefits of VAAI, and more!
