Hi...

anybody have first hands on, on alletra MP ?
please do share your experience, as its greatly appreciated

somehow from the tech briefing, seems like its just a re-wrap 3par aka primera/alletra9k

which still have all the old issues regarding those architecture.. and the VID/PID is still 3par VV

No hands-on experience, but my understanding is that it is pretty far from a re-wrap of the 3PAR/Primera/Alletra 9000. The heart of all those there systems was the ASIC. From what I understand, there is no ASIC in Alletra MP. Also, the MP is based on AMD CPUs (probably due to the higher number of PCIe lanes to feed the NVMe drives), unlike 3PAR/Primera/Alletra 9000 which was always Intel.....

My understanding is also that the concept of node pairs etc is gone and the same with mirrored write cache... I could simply be copy/pasting from this article so I might as well just paste it: https://community.hpe.com/t5/around-the ... -p/7187957 :)

With that in mind, I do think that "the rest" is following in the legacy of 3PAR/Primera/Alletra9000.

Hello,

We recently received an Alletra MP but I did not have time so far to open it :)

Old ASICs are dead now.
A new architecture is born (on 3PAR side), with a more adaptive scaling : add nodes with drives, cages with drives and 2 switches in the middle to get everyone connected together.

It's no more called an Alletra MP but something like Greenlake storage for block, and the same for file with has nothing to compair with a NetApp as the minimum size is around 300 TiB and the target is date science.

recently attended a small hpe event...

and they are saying that alletra MP/block greenlake for block
its ALUA , just like powerstore/flashsystem

and its no longer active/active (paths) like the alletra 9k/pure/powermax

and they dont use write cache anymore.. they use something "staging" that is stored on the disk shelf like a "write journal" ....
