<p class="MsoNormal"><span style="font-size:11.0pt">The Native Rest API is a new feature that is meant to replace mm-commands in the long-term. The Native Rest API feature is being delivered in phases. For the 5.2.2.0 GA, not all the functionality that mm-commands
expose will be available in the Native Rest API. Due to this limitation, all mm-commands will remain available, and complete co-existence is supported by the Native Rest API with mm-commands (meaning you can run both at the same time).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">The Native Rest API will not require GUI administration. With the Native Rest API, there is a new CLI that has a similar look to its equivalent mm-command (-N options, -F options with stanza files, and many
of the same flags per command, just a different invocation).<o:p></o:p></span></p>

I just had an email from IBM about technology preview of the "Native <br>
Rest API" feature in 5.2.1.0<br>
<br>
There are at least two interrelated and important questions that are not <br>
answered in the web page about this "Native Rest API" feature IMHO.<br>
<br>
Firstly the page says it "eliminates" the need to administer the Scale <br>
cluster with the mm-command layer. Does that mean the mm-command layer <br>
is going away? Will I in the future going to forced to use some "naff" <br>
GUI layer to administer a GPFS cluster? Frankly I am quite happy using <br>
the mm-command layer thank you very much and would like to keep it that <br>
way and just be able to ignore the GUI. I do appreciate I might be <br>
somewhat old school in that view but never the less I view GUI <br>
administration of things with disdain.<br>
<br>
Secondly at the moment the Rest API requires installing the GUI. Does <br>
the "native" bit of the title mean that requirement is going away and <br>
there will be a Rest API without the need for the additional complexity <br>
of the GUI nodes? Or is the mm-command layer going away and yes you will <br>
need the extra complexity of the GUI because you are going to have to <br>
suck up administering the system with a GUI?<br>

The new and improved Cluster Export Services (CES) S3 is here<<a href="https://community.ibm.com/community/user/storage/blogs/mike-kieran/2024/08/16/ibm-storage-scale-software-delivers-next-generatio?CommunityKey=1142f81e-95e4-4381-95d0-7977f20d53fa">https://community.ibm.com/community/user/storage/blogs/mike-kieran/2024/08/16/ibm-storage-scale-software-delivers-next-generatio?CommunityKey=1142f81e-95e4-4381-95d0-7977f20d53fa</a>>!
Think of it as High Performance Object (HPO) 2.0 now also running on VMs and bare metal! Check out the test measurements here<<a href="https://community.ibm.com/community/user/storage/blogs/rogelio-rivera-gutierrez/2024/04/25/ibm-storage-scale-performance-ces-s3-tech-preview">https://community.ibm.com/community/user/storage/blogs/rogelio-rivera-gutierrez/2024/04/25/ibm-storage-scale-performance-ces-s3-tech-preview</a>>
where you can get 60 GB/s of read performance. Yes, that?s a byte which is a lot of bits!<br>
<br>
If you want to get Scale storage services on arm64 platforms now, you can! Unofficially, let?s race to running it on your Pi!<br>
<br>
Scale training has also been updated and it?s available on IBM training and Coursera!
