Cisco vPC with Dell S4810 at ToR

Saturday, September 21st, 2013

Cisco’s vPC technology is similar to Dell’s VLT; it enables an access/leaf switch or server to have single LAG connecting up to two separate switches. This allows for an non-blocking, multipathing scenario. You can read more about Dell’s VLT technology and its advantages on my prior blog, Dell Force10 – Layer 2 Multipathing via Virtual Link Trunking (VLT) In this blog, I will configure Cisco vPC between two Cisco Nexus 5548UP switches [NX-OS 5.1(3)N2(1)] down to a third ToR Cisco Nexus 5548UP switch [NX-OS 5.1(3)N2(1)]. I will then replace the third Cisco Nexus 5548UP switch at ToR with a Dell S4810 switch [FTOS 9.0]. (more…)

FCoE with Dell S5000 Converged Switch and Dell MXL Blade Switch [Video]

Wednesday, September 18th, 2013

Check out the latest Dell S5000 converged switch video which demonstrates FCoE with the Dell S5000 converged switch and the Dell PowerEdge M1000e chassis w/ MXL blade switch. The Dell S5000 switch is configured in NPIV Proxy Gateway mode and the Dell MXL blade switch is configured for FCoE Transit. Additionally, the FCoE and LAN connectivity is tested by sending LAN and SAN traffic from the Dell PowerEdge M620 blade server. Multipathing over dual fabrics is also demonstrated by logging into the Fibre Channel switches and observing the FC traffic passing over both fabrics. Just see the second video posted on the following page on Dell’s website here, Dell Tech Center YouTube channel here, or just see the video directly below. (more…)

IT Certifications, Innovation, and Career Growth – Making the Right Decisions

IT Certifications
I often get asked, “What certification should I get next?” There is no right way to answer this question without a deeper analysis of why a certification is being sought in the first place. I’ll focus specifically on IT certifications and direct this article more towards technologists/engineers/tech entrepreneurs. In my opinion, there are too many IT certification hoarders jumping from one certification to the next; I have some friends who definitely fall in this category. I also have my share of certifications as well (Cisco, VMware, etc.), although by no means is IT certifications my first priority or even my second priority. These days it seems like just about every vendor and third party is coming out with some sort of certification and cashing-in on this ‘IT certification’ phenomena. So, do IT certifications really help and should you invest the time and money to get one? (more…)
