Each configured network interface requires its own set of network settings (IP
address, network mask, and gateway). of Linux.
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, 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.
