#Cisco #UCS #Failures prompt #recall program

Cisco is having to replace all the B440 blades that are deployed:
 Update:
The firmware upgrade initially prescribed in this Field Notice has successfully detected FET failures and shut down servers, preventing a potential thermal event. Since this upgrade was released, however, a FET failure on a UCS B440 Blade Server has resulted in a second incident as described above. Cisco is directly contacting UCS B440 Blade Server customers and will replace UCS B440 Blade Servers currently deployed at customer sites. Cisco is making UCS B440 Blade Server hardware modifications, and a hardware replacement program has been launched.


I wonder what kind of hit Cisco will have to take to the bottom line to replace all of the B440 blades!!!!!

#High #Performance #GRE capabilities of #HP #5800 Switch

The 5800 series of switches can do high performance GRE.  You can use up to (3) 1gb or 10gb interfaces and creating a service port, bind them together to deliver higher performance:

Create a Service Loopback Group

[5800]service-loopback group 1 type tunnel

Assign GigabitEthernet 1/0/47 and 1/0/48 to the Service Loopback Group.  (Yes, you cannot use those ports for anything after that!  Sorry)

[5800]interface GigabitEthernet1/0/47

[5800-GigabitEthernet1/0/47]stp disable

[5800-GigabitEthernet1/0/47]port service-loopback group 1

[5800]interface GigabitEthernet1/0/48

[5800-GigabitEthernet1/0/48]stp disable

[5800-GigabitEthernet1/0/48]port service-loopback group 1

Create the GRE Tunnel Interface and assign the Service Loopback Group to it.

[5800]interface tunnel 0

[5800-Tunnel0]ip address 192.168.1.1 24

[5800-Tunnel0]source 1.1.1.1

[5800-Tunnel0]destination 2.2.2.2

[5800-Tunnel0]tunnel-protocol gre

[5800-Tunnel0]service-loopback-group 1

This configuration should allow up you to go over 1Gbps in performance on a GRE tunnel on the 5800.


One good point to make... you are NOT actually using the ports you are assigning to the service group.  You are assigning their ASIC resources.  The ports themselves are not usable as ports any longer. The GRE tunnel would take whatever route out of other interfaces to get to its destination.

#IOS & #NX-OS definitely not the same OS

Even after being out for quite a while..there are still a lot of differences between the two...
