StorNext 3.1.3 Installation Guide 4
Partitioning Local Hard Disks 1
StorNext can be installed on any local file system (including the root file
system) on the MDC. However, for optimal performance, as well as to aid
disaster recovery, follow these recommendations:
• Avoid installing StorNext on the root file system.
• Partition local hard disks so that the MDC has four available local file
systems (other than the root file system) located on four separate
hard drives.
LAN Requirements 1
The following LAN requirements must be met before installing StorNext
on the MDC:
• In cases where gigabit networking hardware is used and maximum
StorNext performance is required, a separate, dedicated switched
Ethernet LAN is recommended for the StorNext metadata network. If
maximum StorNext performance is not required, shared gigabit
networking is acceptable.
• A separate, dedicated switched Ethernet LAN is mandatory for the
metadata network if 100 Mbit/s or slower networking hardware is
used.
• The MDC and all clients must have static IP addresses.
Verify network connectivity with pings, and also verify entries in the
/etc/hosts file.
• If using Gigabit Ethernet, disable jumbo frames and TOE (TCP
offload engine).
Note: You can run the pre-installation script to help determine the
estimated size of and optimal location for StorNext support
directories. For more information, see
Pre-Installation Script
on page 8.
Note: StorNext does not support file system metadata on the same
network as iSCSI, NFS, CIFS, or VLAN data when 100 Mbit/s
or slower networking hardware is used.
