Elastic Storage Server (ESS) is a high-capacity, high-performance storage solution that combines IBM® Power Systems servers, storage enclosures, drives, software (including GPFS Native RAID), and networking components. ESS uses a building-block approach to create highly-scalable storage for use in a broad range of application environments.

ESS 5.3.4 release brings in multiple enhancements on the lines of better security and monitoring along with new feature/functions. Also upgraded the Red hat version to RHEL 7.6 with latest kernel and patches. In this release team played missions critical role to implement SUDO support, SELinux Support, enabling firewall support, GPFS admin central support, Broadcom adapter support and other ESS security vulnerability fixes.

Here are the all details:
• Support of new RHEL OS 7.6.
• Mmvdisk now defaulted for RGs, Vdisks, NSDs and FS creation.
• Added SUDO support where customer now can have SUDO enabled ESS cluster to add next level of security.
• Added SELinux support to record better auditing of GPFS nodes.
• Added Firewall support to enable system to have firewall services running and stop any unwanted ports to stop hacker attack.
• Added GPFS admin central support to stop unwanted SSHes between GPFS nodes. With this feature only, EMS node can do password less SSH to GPFS allowing less chance to hacker to get access to ESS system.
• Added HTTPS based validation for ESS callhome (replaces unsecured HTTP version to HTTPS).
• Protocol nodes upgrade support to 5.3.4
• Added Broadcom Adapter support as part of deployment. Now customer has another option to order ESS with Broadcom adapter (less expensive adapter than Mellanox).

    Support for GLxC MES configurations

  • GL1C -> GL2C
  • GL2C -> GL4C
  • GL4C -> GL5C

• One more point to be noted here that once upgrade is done from legacy mode to current release that is 5.3.4, customer must convert legacy recovery mode to mmvdisk default.
• GSS commands logging: From ESS v534 onward, all GSS commands will be logged in at a new location ‘var/log/ess’, on every new system install or system upgrade, new directory will be created under the aforesaid location by name ‘gsslog_‘,
Example: ‘gsslog_201906040016’, here timestamp is the date and time at which the system installs or system upgrade is performed.
• Took out the option for ESA security certificates.
