2.11 Network Configuration
CAUTION!
For effective bonded network use, a properly configured network switch is required.
(A network switch is not supplied with the ETERNUS CS800).The ETERNUS CS800
bonding settings must match the switch settings. If the switch settings and the
ETERNUS CS800 settings do not match, your system may become inaccessible
through the switch.
Performance Guidelines
The throughput and resilience of a ETERNUS CS800 depends on various parameters,
such as
l
on the model and configuration level (Entry/Scale, interfaces, the number of disk
drives)
l
the data which should be backed up (deduplicable, compressible, new or already
stored in the blockpool)
l
the backup software and the method used by it
l
the client operating system
l
the presentation layer (NFS, CIFS/SMB, VTL, OST)
l
non-backup jobs performed in parallel (replication, space reclamation)
Therefore a general recommendation cannot be given here. As a rough guideline only: If
each backup file/job written concurrently to the system is considered as a stream,
maximum of throughput is reached with 16 to 32 (Scale) or 5 to 16 (Entry) streams in
parallel. The
given ranges are appropriate for the configuration levels and the presentation layers used
in parallel.
NAS shares provided by ETERNUS CS800 are optimized for backup. Using NAS shares
to store many small files may degrade the throughput of the system (e.g. inline
throughput, replication) significantly.
