About the StorNext
M660 Metadata
Appliance
The StorNext M660 Metadata Appliance offers the powerful file-sharing
capabilities of StorNext in an optimized appliance package. The
StorNext M660 comes with a pair of metadata controller (MDCs) nodes
in a High Availability (HA) configuration and a high-performance
metadata array. An optional metadata disk expansion unit adds another
metadata array to the system for additional file systems, performance
and capacity. The appliance comes in two models: the StorNext M661
and M662.
Note: At times this guide uses StorNext M660 as a generic term that
applies to the StorNext M661 and the StorNext M662 models.
When information pertains to a specific StorNext M660 model
only, those differences are noted.
MDCs coordinate SAN file access across clients. Additionally, the
standby node can be used as a distributed data mover (DDM) host using
the included license, or both MDC nodes can be used as LAN client
gateways in non-Lattus systems.
During installation, the StorNext M660 can be configured for use in
different storage environments - in StorNext environments operating as
a StorNext Metadata Controller (MDC) High Availability (HA) pair with
access to both disk and tape libraries, or as a StorNext MDC HA pair
with access to disk, tape, and Lattus storage.
Note: Access to Lattus storage is available on M662Metadata
Appliances only.
