from my POV the recommendation for firmware level depends on a lot of factors , such as the feature used on the current level {like HyperSwap elimenated after specific version maybe 8.7.0.1 I think https://www.ibm.com/support/pages/node/706911 } and what is new and what the fixes includes in the new version. Usually, enterprises update to latest -1 LTS stable version which means the third number of firmware level need to be 0 like 8.7.0.x or 9.1.0.x .
Also, I believe the compatibility is subject to the specific hardware model, software version, and the configuration (e.g., drive interface like SAS or NVMe, and protocol) not to drives firmware level.

Subject: Recommended upgrade for FS7300?
Thank you.
- How long before a firmware is "recommended". 70 days after availability? After bugs are found in it and the latest release comes out then the previous buggy one is "recommended"?
- If the new FS7300 comes with level 4 drives does that cause any compatibility issues exchanging data between the two? I believe there are some features only available with level 4 drives.

Dear Robert,
Hope you are doing well,
It's your decision to decide which level you want to go to, both levels 8.7.0.8 and 9.1.0.2 you can update/upgrade to, concurrently and Long-Term Supported (LTS). Also, both level remediate the Vulnerability affected your system.
However, the latest firmware level for FS7300 is 9.1.0.2 as you can find here https://www.ibm.com/support/pages/node/5692850#_Latest_IBM_Storage_Virtualize_Code
Furthermore, you can find drives firmware available levels at https://www.ibm.com/support/pages/node/873170 , you need to insert you drive Model Number to see the available firmware levels. but I believe that you have the latest firmware installed which is 3_1_15 .
Please note that you have to read the firmware ReadMe file comes with installation packages on IBM ESS to make sure that the update/upgrade process is non-disruptive.
Finally, you can find the Lifecycle and support matrix for all IBM storages at https://www.ibm.com/docs/en/stg-vss-vds?topic=lifecycle-support-matrix .
Please feel free if you have any other questions or concerns.
Best Regards.
