EonStor / EonStor DS S12/S16/S24 Series
preferred that all the disk drives within a chassis have the same capacity.
Tiered storage configuration is supported, e.g., 150GB SAS drives in your
RAID enclosure and 750GB SATA drives in JBODs. However, you should not
include both SAS and SATA drives in a logical drive.
A spare drive should have a minimum capacity that is equivalent to the largest
drive that it is expected to replace. If the capacity of the spare is less than the
capacity of the drive it is expected to replace, the controller will not proceed
with the failed drive rebuild.
When rack-mounted, leave enough slack in the cables so that they do not
bend to a diameter of less than 76mm (3 inches).
Route the cables away from places where it can be damaged by other devices,
e.g., foot traffic or fan exhaust.
Do not over-tighten or bend the cables.

Host-Side Topologies
The primary concern for configuring host-side topologies is to avoid points of failure.
It is therefore recommended that the host ports be connected to at least two HBAs. It
is also preferable to apply corresponding host port type switches (eg. use Fibre
switches for Fibre host ports).
NOTE
In order to manage the fault-tolerant data paths and to optimize data throughput on
multiple data paths, it is necessary to apply EonPath multi-pathing software or
utilities such as Linux Device Mapper.

Host-Side Parameters
It is STRONGLY recommended that users use the default settings with their system.
Should you feel the need to adjust your host-side parameters, please consult on-site
technical personnel or technical support.
