HPE 3PAR Storage CMP leaks

[Gigen_Dev_1987]

Need help to understand what is Cache Memory Page leak, any help would be helpful.

Basically it's a leak in CMPs.  I would suggest you just install the patch before your system crashes.

Any documentation in the patch?

Hello Dennis, 

Thanks for replying. I am not a customer but I am new to HPE and have come across this term and wanted to know a layman understanding of this term.

Thanks,

Gigen

The data cache is composed of CMPs.  They are used to cache the data before reading/writing to PDs.

They are also used to transfer info from one node to another.

If you have a leak, this memory becomes lost and if enough, there is no memory to do I/Os, etc.
