Nexenta Storage Appliance 0.99.7 (Default branch)
04-02-2008
Nexenta Storage Appliance is designed and built to operate as a 2nd tier storage alongside pre-existing commercial storage, providing online continuation of data for months and years, with tapes relegated to archival purposes only. The appliance is targeted for 2nd-tier NAS and iSCSI applications requiring extremely low cost storage as well as dramatically simplified provisioning, expansion, backup, replication, and archiving. It can also be used as a primary NAS in businesses that wish to expand at closer to commodity pricing. It supports unlimited snapshots, snapshot mirroring (replication), and easy management of extremely large storage pools. License: Other/Proprietary License with Free Trial Changes:|

bool mysqlnd_qc_set_storage_handler (string $handler) DESCRIPTION
Sets the storage handler used by the query cache. A list of available storage handler can be obtained from mysqlnd_qc_get_available_han- dlers(3).
