Zobst is always thinking of the needs of the Zimbra administrator - regardless if they are supporting millions of accounts or a few hundred - and how they want the Zimbra product to evolve.  Zobst Storage Manager has been designed and the implementation team is lead by a former principal engineer responsible for supporting millions of accounts and who implemented many improvements to Zimbra.  

The use of object storage greatly simplifies the life of a Zimbra administrator.  Unlike the use of HSM solutions, which actually increase IO demands and system admin operations, using object storage simplifies your day.  No longer are you concerned with the blob IO demands or capacity requirements on the Zimbra mail stores.  Balancing of users across backend is greatly simplified, if not eliminated.

In addition:

• Zobst Storage Manager does not modify Zimbra code!  ZSM is implemented by overloading the Zimbra provided StorageManager API that has been available in Zimbra for years.  
• ZSM is available for numerous Zimbra versions and editions:
• Daffodil (ZCS 10.x)
• Zimbra 9
• Zimbra 8.8.15 Community and Network Editions
• Installation packages for every Linux operating system and version supported by Zimbra
• RedHat Enterprise Linux
• Rocky
• CentOS
• Oracle Linux
• Ubuntu LTS releases
• Simple configuration with text files and standard Zimbra tools
• Validate and test Zobst Storage Manager independently of Zimbra
• Detailed logging, using standard Zimbra logs, so that existing tooling can continue to be utilized.

• Extensive metrics collection integrated with Zimbra so you can understand how your storage in interacting with ZCS
