About deduplication performance
Manyfactorsaffectperformance,especially theserverhardwareandthe network

Table 2-4 provides information about performance during backup jobs for a
deduplication storage server. The deduplication storage server conforms to the
minimum host requirements. Client deduplication or load balancing servers are
not used.
See About deduplication server requirementson page 23.
Table 2-4
Deduplication job load performance for a deduplication storage
server
DescriptionWhen
Initial seeding is when all clients are first backed up.
Approximately 15 to 20 jobs can run concurrently under the following
conditions:
The hardware meets minimum requirements. (More capable hardware
improves performance.)
Nocompression.Ifdataiscompressed,theCPUusageincreasesquickly,
which reduces the number of concurrent jobs that can be handled.
The deduplicationrate isbetween 50%to 100%.The deduplicationrate
is the percentage of data already stored so it is not stored again.
The amountof datathat isstored is lessthan 30%of thecapacity ofthe
storage.
