QuantaStor v3.14 Released

The latest maintenance release of QuantaStor SDS (v3.14) was published on December 30th, 2014 and comes with several new features. Some highlights include:

  • Cascading replication of volumes and shares allows for replicating data in an unlimited chain-linked fashion from appliance to appliance to appliance.
  • Kernel upgrade to the Linux 3.13 that adds support for the latest 12GB SAS/SATA HBA and RAID controllers as well as the latest 40GbE network interface cards.
  • Advanced universal hot-spare management to the ZFS-based storage pool type that’s enclosure aware and makes hot-spares universally shared within an appliance and across multiple appliances.

This is also the first release that has some initial Ceph support but at this time we’re only working with partners via a pilot program around the new Ceph capabilities. For more information about the pilot program please contact us here and note that broad GA availability of Ceph support is planned for late Q1 2015.

Below is the full list of changes. Linux kernel update instructions can be found on the OSNEXUS support site.

  • adds sysstats to send logs report
  • adds swap device utilization monitoring and alerting on high swap utilization
  • adds support for unlimited users / removes user count limit license checks for all license editions
  • adds support for scale-out block storage via Ceph FS/RBDs (pilot program only)
  • fix for CLI host-modify command
  • fix for pool discovery reverting IO profile selection back to default at pool start
  • fix for web interface to hide ‘Delete Unit’ for units used for system/boot

  • fix to iSCSI close session logic for when multiple sessions are created between the same pair of target/initiator IP addresses
  • fix to auto update user specific CHAP settings across all grid nodes when modified
