HPE NIMBLE HF40 NVDIMM size and NIMBLE conntroller cache memory size

Hello support,

Where i can find the information about NIBMLE HF40 controller NVDIMM/NVRAMM size and battery backet NAND flash size?

In the NIMBLE quickspecs i only found the size of the conntroller memory 64 GB, and what amount of this connroller memory is used for the read/write cache?

Thanks in advance,

/Maxim

Hi Max! Have you checked on Infosight?

https://infosight.hpe.com/org/urn%3Ainfosight%3A49add12e-93e6-4c0e-8e45-aeaa1176cea9/resources/nimble/docs

Maybe you could make some research there. I'm not sure if I understand your question.

We never expose such level of details outside HPE, in Nimble the heart is CASL which is our inteligent file system built within array for maxmizing array performance without requires huge amount of hardware resoruce.

In HF array we use SSD for read-cache extention,, size way more than traditional DRAM used by our competitons.  And write performance is all about controller's CPU horsepower therefore size of write cache should be irrlevant.
