SIOS Technology has announced the immediate availability of SIOS Protection Suite for Linux, version 9.6. The latest version of its clustering software enhances data integrity protection in Microsoft Azure and enables up to five times faster recovery time for SAP HANA databases.
The new SIOS Azure fencing mechanism in version 9.6 integrates closely with native Microsoft Azure fencing agent to eliminate a potential threat to data integrity called split brain. This issue occurs when servers in a cluster lose communication and begin changing the same data at that same time, causing data integrity issues.
The SIOS Protection Suite fencing mechanism automatically detects “split brain” scenarios and interfaces with the Microsoft Azure fencing agent to deactivate the secondary cluster node(s). This feature not only protects data integrity, but it also saves customers money by eliminating the need to deploy and pay for an additional server for fencing capabilities.
According to the company, SIOS Protection Suite for Linux 9.6 enables five times faster recovery of SAP HANA databases in the event of a failure. Enhancement to the SIOS application recovery kit (ARK) for SAP HANA dramatically improves RTO for both resource and application failures, by limiting the actions of the HANA quickCheck function and performing fast, efficient failover of operations to a standby server.
The latest version also supports additional platforms and operating systems, including: SUSE Linux Enterprise (SLES) 15.3, Oracle OS 8.4, and Oracle 21c db.
