Best Practices Using ZFS For SAP ASE Database

SAP Adaptive Server Enterprise (ASE) database 16.0 and 15.7 are certified to run on Oracle Solaris 11 systems using ZFS as data storage and logs. Recent testing with OLTP workloads on Oracle SPARC systems with Solaris 11 show better or on-par performance with ZFS compared to UFS or raw devices.  

Oracle Solaris ZFS is a powerful file system that combines file system capabilities with storage features that are traditionally offered by a volume manager. ZFS is the default file system in Oracle Solaris 11 and includes integrated data services, such as compression, encryption, and snapshot and cloning. Oracle Solaris and ZFS are also the foundation of Oracle ZFS Storage Appliance.  

ZFS Best Practices For SAP ASE Database:

  • Create separate zpools for data and the transaction log.
  • Create zpool for data using multiple LUNs for better I/O bandwidth.
  • ZFS record size for data is one of key parameters for optimal performance. The default  value of 128K is too large and causes page overhead.  For Solaris SPARC systems with the DB page size of 8K or less, a ZFS record size of 32K provides  the best performance for both file system block and raw zvol.
  • Place ZIL (ZFS Intent Log) on SSDs for improved latency of both data and transaction log.
For more details see SAP Note  2300958 : ZFS Certification of SAP ASE 16.0 and Sybase ASE 15.7 on Oracle Solaris 11 (requires SAP login).

ZFS and Solaris: storage optimization for the cloud

Cloud computing has been one of the most discussed topic over the year. What is usually less discussed is the technology behind cloud-computing, though this is no secret that virtualization is playing a key role. Cloud data-centers will be loaded with virtual machines each of these machines potentially requiring in disk-space what a complete operating system (OS) requires[Read More]

My swap space on an SSD?

If I consider the gain in latency that an SSD brings versus a capacity disk - in the region of 100x - the solution seems obvious. Swapping must be much faster with an SSD. Since RAM is expensive versus SSD, I could even be tempted to design a system with little RAM and a large swap space on SSDs. In other words, I can ask myself if trying to prevent my system to page is still a good fight?[Read More]
