Let me clear this up for everyone.
The Improvements to the Storage Usage was 1st implemented in the following releases:
For customers standardizing on 10.05, please upgrade to release 10.05.0021
or later including moving up to 10.06 releases.
customers standardizing on 10.04, please upgrade to release 10.04.3031
or later including moving up to 10.05 or 10.06 releases.
customers standardizing on 10.03, please upgrade to release 10.03.0101
or later including moving up to 10.05 or 10.06 releases.
8400, 8320 customers that are running 10.00, 10.01 or 10.02 -- you'll have to upgrade to 10.03.0101 as an intermediate step to move up toe 10.04 or above (an update to the schema requires this intermediate step) See the release notes for upgrade procedures.
Yes, most affected are 6200 or 6300 VSF stack Members (the Conductors are not as affected).
6400 & 8400 Management Modules running as Standby (the Active MM is not as affected)
8320, 8325 are not as affected.
Nonetheless, we recommend upgrading to the 10.05.21 or 10.06 releases,
across the board because of the improvements, which also include improved error warnings when the Storage system reached 90%, 100% and beyond wear levels. With the newer software, that should take years to reach on new systems.
All of the recent updates that are "later" than the above referenced numbers have these improvements already implemented.
Please be aware that ANY switch you receive from distributors, or resellers or even recent RMA replacements, most likely has not been built with the newer software.
PLEASE UPGRADE before deploying your switches. DO NOT CONSIDER any release not mentioned above as 'immune' to this storage impact -- please upgrade (yes, even the 83xx switches).

Subject: Product Bulletin: CX Storage Improvement Software Releases - November 2020
Hi all!
reading the Product Bulletin "CX Storage Improvement Software Releases - November 2020" released just few days ago (last Saturday, if I'm not mistaken) I can't understand what exactly Aruba CX series are susceptible of reported "storage exhaustion affecting the usable life of the non-volatile memory" and what are not.
The bulletin reports all Aruba CX Switch series as affected - minus the Aruba 8360 (probably because it is running only on AOS-CX 10.6 or newer) - saying that all Aruba CX Switch Series are currently susceptible to storage exhaustion ("CX 6200, CX 6300 stack members and CX 6400 or 8400 management modules running as standby")...thus...given that annotation, it seems to me that impacted series are mostly 6200, 6300, 6400 and 8400 and only in particular configurations while others are not, totally ("Standalone 6200/6300/83xx, 6200/6300 stack commanders and 6400/8400 with single management module/active management module are not susceptible to storage exhaustion.").
The point is that the Important Information message available on 10.05.0021/10.04.3031 Release Notes:
is totally absent on Aruba 8320 and 8325 Switch Series' Release Notes for those builds.
Is the absence of that informative message reasonable or not on Aruba 8320/8325?
In other terms it would be nice to understand if, as example, a standalone Aruba 8320 switch (running any build of ArubaOS-CX 10.03, 10.4 or 10.5) shall be upgraded to suggested versions (10.04.3031 or newer, 10.05.0021 or newer) no matter what, for the reason listed above as well as for having important security reports like the CVE-2020-7121, CVE-2020-7122 fixed or simply it's not mandatory at all (because Aruba 8320 and 8325 are de-facto not susceptible of the storage exhaustion issue).
That's to understand the urgency behind recommended update and to understand if the issue (as its fix) has a software origin...if so...maybe...some older software versions (such as 10.03) are currently immune while others (10.4 or 10.5 are affected and are affecting the underlying hardware on particular Switch series only).
