I just received it today. It took me 6 months to achieve it, compared to 1 year for my CCSP. It’s easier than I thought, mostly because I have been doing Cisco Nexus and UCS for a few years.
The others are my other Cisco certs. Yes, I have that many
I found these pictures while looking for resources to make a Powerpoint slide.
This is the best way to explain the 7-tiers of Disaster Recovery
And this one is to explain the Storage 3-2-1 concept for Data Protection best practice
I found this image on the Internet. This is the best way to explain EMC Protection Features to clients
I’m setting up a new Nexus 5000 vpc cluster. For the keep alive links, I used the old 1GB SFP modules because the links don’t send much traffic. However, it didn’t work
Now that’s interesting because from the Cisco Datasheet, it says
Supported Tranceiver Options:
Cisco SFP-10G-SR 10GBASE-SR SFP+ module (MMF)
Cisco SFP-10G-LR 10GBASE-LR SFP+ module (SMF)
Cisco SFP-H10GB-CU1M 10GBASE-CU SFP+ cable 1m (Twinax cable)
Cisco SFP-H10GB-CU3M 10GBASE-CU SFP+ cable 3m (Twinax cable)
Cisco SFP-H10GB-CU5M 10GBASE-CU SFP+ cable 5m (Twinax cable)
Cisco GLC-T 1000BASE-T SFP
Cisco GLC-SX-MM GE SFP, LC connector SX transceiver (MMF)
Cisco GLC-LH-SM GE SFP, LC connector LX/LH transceiver (SMF)
Cisco SFP-GE-T 1000BASE-T SFP, extended temperature range
Cisco SFP-GE-S GE SFP, LC connector SX transceiver (MMF), extended temperature range and digital optical monitoring (DOM)
Cisco-SFP-GE-L GE SFP, LC connector LX/LH transceiver (SMF), extended temperature range and DOM
Cisco DS-SFP-FC4G-SW 4-Gbps Fibre Channel SW SFP, LC (for Fibre Channel expansion module ports)
Cisco DS-SFP-FC4G-LW 4-Gbps Fibre Channel LW SFP, LC (for Fibre Channel expansion module ports)
Cisco DS-SFP-FC8G-SW 8-Gbps Fibre Channel SW SFP+, LC (for Fibre Channel expansion module ports)
Cisco DS-SFP-FC8G-LW 8-Gbps Fibre Channel LW SFP+, LC (for Fibre Channel expansion module ports)
So I spent a little bit of time playing with the config. It turned out that you have to tell the switch to run at 1Gb on the SFP
I’m on the newest version of Nexus, ver 7.0 N1(1). Not sure why it doesn’t auto-detect the speed. The NX-OS is still evolving, stay tuned for more tips and tricks.
Cisco UCS provides the infrastructure to support the highest levels of service availability through a stateless server environment. Stateless servers are logical servers (OS and application images) that can run on any physical server or blade in a way that encapsulates traditional hardware identifiers (World Wide Node Names [WWNNs],World Wide Port Names [WWPNs], MAC addresses, etc.), as integral parts of the Service Profile identity
The foundations of Service Profiles are these logical building blocks (for example, pools and policies) that can then be captured for reuse. Furthermore, virtual network interface card (vNIC) and virtual host bus adapter (vHBA) templates can be referenced for use in higher-level Service-Profile templates. To reduce server provisioning time, Service Profile templates can then be used to rapidly instantiate actual Service Profiles (possibly automatically associating those instantiated service profiles with actual physical servers and blades).
The relationships between these internal building blocks are all rationalized and normalized. Higher-level objects (such as vNICs) can be created by referencing lower-level objects (such as pools and policies). This normalized data model promotes reuse and removes the need for duplication of common objects.
I recently discovered that my blog didn’t display the posts to regular users since September 2013. While it still shows the new posts when I login as an administrator, it doesn’t show anything for the viewers. After checking the PHP source code, I found a cookie error that I made when I edited the script back then
Stay tuned! I will fix this shortly.
