Expansion Arrays
Chapter 4 Storage Configuration and Expansion
63
• If your source server uses a UNIX SnapTree and has permissions assigned to
local or NIS users, use an NFS connection for migration.
Note
Local users that have UNIX permissions on the source will not be created
on the target with the same UIDs.
Migrating from a SnapOS Server
When migrating from a SnapOS Server to a GuardianOS server, permissions will
not be correctly retained.
Expansion Arrays
Note
This section only applies to SnapServer models that can attach an expansion
array. See the
Configuration and Hardware Options Guide
for expansion array options.
Note
If GuardianOS detects an expansion unit that is not integrated with the
SnapServer, a warning displays across the top of the Disks/Units screen with a link
to information about the orphan expansion unit.
To increase the capacity of a SnapServer, Overland Storage offers the SnapServer
EXP E2000 and the Snap Expansion S50 expansion arrays. Details on installing a
SnapServer E2000 or a Snap Expansion S50 are provided in the
Quick Start Guide
that comes packaged with the array. The guide is also available for download from
http://www.snapserver.com/support
SnapServer EXP E2000
The SnapServer EXP E2000 is a 2U expansion array with up to twelve SATA II or
SAS disk drives, or a combination of SAS and SATA disk drives up to a maximum
of 12. It ships as a set of unassigned disks with no RAID configuration. Up to five
SnapServer E2000s can be connected to a SnapServer NAS N2000.
Note
Specific configurations are recommended when SAS and SATA drives (or
drives with different rotational speeds) are combined in the same expansion array.
Be sure to review “Adding New Disk Drives to Increase Capacity” on page 68
before configuring a mixed-drive array.
A SnapServer E2000 expansion array is accessed and managed through the
SnapServer to which it is connected. The expansion array has no physical
connection to the network. After the SnapServer E2000 is installed and powered on
(see the
E2000 Quick Start Guide
for details), the array’s disk drives appear as
unassigned drives, allowing the administrator to configure RAIDs as necessary.
