HP p410i array controller – what happens if i add memory

cachecontrollerhpwindows-server-2008

I have a p410i array controller that only has 256ram. We want to create a raid 5 so we have procured a 512 write back cache module.

If we install the write back cache, will this erase the existing raid information.

The server currently has 2 disks in raid 1. 6 are spare waiting for an upgrade to create a raid 5. the concern is if we replace/upgrade the memory for the controller, we will wipe the existing production raid 1 array.

Thanks in advance.

Short answer is "no". HP array controllers do not store array-specific information only on the controller itself or its spare parts like writeback cache module, they produce a copy on the physical disks included into array. You can replace cache module, add/remove memory or replace the controller entirely (due damage or other reasons) - the array configuration will be read from the disks automatically.
