Nimble SAN Firmware Upgrade - April 24, 2019
Posted by Pete Carstensen on 23 April 2019 12:50 PM
[Completed, 23:22 4-24-19]:  This maintenance is complete on all Nimble Storage Arrays.  As expected, no impact to workloads was observed.  

Date: 
April 24, 2019
Time:  10:30PM MT

Purpose of Work:
Nimble Storage has let us know that a couple of our storage arrays are running on a version of NimbleOS that has a security vulnerability that could result in remote code executions and remote denial of service attack.  We will be upgrading our storage arrays to newer firmware that is not impacted by this vulnerability. (CVE-2017-9765)

Impact of Work:
Historically, we have performed many Nimble Storage upgrades which have been completely hitless and not at all noticeable to any workloads consuming storage from our arrays.  Accordingly, we do not anticipate any impact, but there is always a slim possibility that connectivity to the storage arrays will be disrupted, resulting in workloads relying on the storage to hard reboot.

Please contact us with any questions / comments / concerns.
