Information about the reading cache of the controllers

Good Morning!

Some time ago I have some doubts about reading the cache memory of the HPE controllers. Currently I have this configuration: P440 4GB, RAID 8X6TB. The operating system is managed by the integrated controller b140.

I have a lot of reading traffic, and I've been reading that allocating read cache to the controller, slows down access to the disks. The biggest reading traffic I have on the server is P2P.

I wanted to know if there is any documentation about it, or someone can help me really understand the reading memory, if the beneficial for when there is a large reading traffic, or change, is irrelevant.

Thank you!

Smart Array Controller Cache technology can provide benefits for both read and write scenarios.

Ratio of read to write Cache needs to be set based on specific workload in a given environment.

 

Please refer the following links for documentation:

Please feel free to reach back if any further queries.

Hello, good morning, thank you for your response.

The first link does not work, it takes me to a blank page, the second link is a PDF if I can see it. Thank you

See this thread.  It mentions a problem with displaying PDFs in firefox.

The workaround worked on that link.

Thank you very much. I always use Firefox, and I had not realized that I could not open the PDF online. Thank you very much!

It used to work but they changed something to add feedback links?

(Was that helpful enough for a kudos on by reply above?  :-)

Firefox if I open PDF documents, but in the configuration I have previously asked me what I want to do with the document. If in the configuration I put the preview in Firefox, if that works. Thank you very much!
