Cisco UCS FlexFlash /SDCard Configuration for Booting Server Operating System.
As most of the Cisco UCS users might be aware that Cisco has now add a lot of improvements and new features on the latest upgrade 2.2(1e).
One of the feature which we have started using is Cisco FlexFlash which is an SD Card. Its fully support if you buy the SD Card from Cisco and we can even do mirroring on the Flash cards for redundancy, we will be installing ESXi Server 5.5 on these blades after mirroring them.
So where and How to install the Secure Digital (SD) Card ?
If the CISCO UCS B200 Blade is in the Chassis you will need to power it off and slide it out just half way through and you should find the SD Card slot on the left
for more information on how about this can be found on the following link http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/hw/blade-servers/B200M3.html
As you might be aware that CISCO UCS blade is just as equal to a brick and all the configuration is done on the logical server called Service profile. you will need to create a new / clone an existing Service profile template and modify with the below changes which I have shown below on this post.
You will have to create a boot policy with CD Drive (legacy ) and SD Card and Some time you may end up getting this error ‘ advanced boot or secure boot configuration cannot be applied to the specified server There are not enough resources overall ‘ if you see it follow my blog post.
I have to make you aware that if you want to use SD card with Mirroring or RAID 1 you have to create the following new policies and create a Boot policy as mentioned above.
1. Disk policy with Mirror and any configuration
2. We have to create two Scrub policy under policy ( you can call it any thing you want which makes you understand what configuration you have selected)
- Flex Flash Scrub
- No Scrub
So where will you find the Flex Flash Controller?
Click on the Left pan on Equipment and Select the Chassis then the Server, on the right you will find the below details
click on Inventory and select the last tab which is Storage on the Storage tab you will find FlexFlash Controller
Note: this FlexFlash is only support if you are running 2.2 (d1) firmware.
