Intel has released a new firmware for the Intel JBOD2224S2DP storage enclosure that deals with the enclosure delivering the same Enclosure ID to Windows Server 2012 R2 Storage Spaces.
Why is this firmware mandatory?
Because up until now when two or more Intel JBOD2224S2DP units were connected to Scale-Out File Server nodes and one ran the Get-StorageEnclosure PowerShell command one would get the same ID back for every one.
The firmware problem killed Storage Spaces enclosure resilience. What is that you ask?
In Storage Spaces, with a Two-Way or Three-Way mirror one can have three enclosures set up to allow one to drop out completely and things keep going.
If one has configured five enclosures with a Three-Way Mirror then the Storage Spaces setup can tolerate two enclosures dropping out.
If the Intel JBOD unit is already in a production setting with plans to add more enclosures at a later date then it is important to note that this firmware update would be required prior to adding the new units.
For new setups, this firmware update should be a part of the preparation steps for the JBOD prior to implementation or baseline testing.
