I like the command line, I’ll admit it, it’s old-school but l am old-school. Clicking around a graphical interface is all well and good but if you want to get something done the command line is the way to do it. My high school years, college years and early career were a variety of Unix flavors, VMS, DOS, CP/M with an assortment of editors, programming languages and shells.
What I love is when a graphical interface can be managed via a command line. This way I know that I can use all my favorite tools (old and new) to get done what needs to be done. What needs to get done sometimes is taking the point and click out of a task. That’s my focus today.
Here’s the scenario, download SNMP MIBs for UCS. Go to that web page and you need to get very clicky, perhaps even right-clicky and select the “save as” option. More clicks, with potentially over 100 MIBs to download that’s 200 plus clicks, and the repetition is as mind numbing as a top 40 radio station.
You are probably thinking that CITEIS is a typo – but it’s not. In fact, CITEIS stands for Cisco IT Elastic Infrastructure Services and it’s the name that Cisco’s IT department coined for our internal private cloud.
You can read more about CITEIS here, including an explanation of the two options: CITEIS “Express” for on-demand access to virtual compute resources from a shared pool of resources; and CITEIS “VDC” (Virtual Data Center) to provision your own virtual data center with a reserved pool of compute, storage, and network capacity.
We recently recorded a brief demo video of the Express version so you can see how it works:
Cisco ACE 30 Module for Catalyst 6500 Series switch
Application performance and reliability are critical issues for data center applications. Cisco just recently released a case study on Denver-based Johns Manville, a leading manufacturer of quality building products and how Cisco helps maximize availability and performance of their SAP inventory control system.
Johns Manville relies on an SAP business system in its manufacturing plants and warehouses for inventory management. Plant floor employees, such as forklift drivers and shipping agents, continuously enter data into the inventory management system through an SAP portal as orders are entered, packed, and shipped, and as inventory is moved. Forklift vehicles are equipped with PCs and scanners that connect to the SAP portal through wireless connections. The SAP portal also provides access to the plant intranet and other applications.
Johns Manville deployed two Cisco ACE modules in its Cisco Catalyst® 6500 Series core switches to load-balance incoming SAP inventory control traffic to the least-busy servers. The module uses best-in-class application-switching algorithms and highly available system software and hardware to increase application availability. A single module can manage up to 16 Gbps of application traffic, and up to 64 Gbps with four modules in a single Catalyst 6500 Series switch chassis. Read More »
Today, Cisco introduced the Third-Generation of Fabric computing. The power of unification can be seen in all aspects of the Cisco Unified Computing System (UCS). It unifies physical and virtual compute environments. It integrates the server and network access. It also unifies and simplifies the management of rack and blade servers. The choice between using blade and physical server is not obvious and usually sparks a heated debate. The Cisco UCS Manager with B-Series blades and C-Series Rack-mount servers makes this argument moot.
Without passing judgment on whether rack or blade servers are better, lets begin by listing the benefits of the two form factors. Blade server use is growing and there are many reasons for this:
Data center space / Power / Cooling constraints – Data center space can get expensive depending on the location. In this CBS 60 minutes segment, proximity to the stock exchange is extolled. This fascinating video shows the collocation of data centers in urban nerve centers. I am sure data center space in these locations commands a premium. Energy efficiencies also become important in the overall cost structure. Power constraints may also favor the use of blades that consume less power than equally powerful rack mount servers.
Today Cisco announced an expanded portfolio of third generation UCS Networking products that improve Datacenter scalability, performance and agility with industry leading capabilities. The announcement includes the following new products:
1. A new Fabric Interconnect (Cisco UCS 6296UP) that doubles the switching capacity of the data center fabric to improve workload density (from 960Gbps to 1.92 Tbps), reduces end-to-end latency by 40 percent to improve application performance and provides flexible unified ports to improve infrastructure agility and transition to a fully converged fabric
2. A new Chassis I/O Module (Cisco UCS 2204XP) that offers enhanced resiliency and utilization with Port Channeling, and an option for 80 Gbps, in addition to 160 Gbps, down to each chassis (from 80Gb to 320Gb to the blade) to handle workload bursts
