      OpenDedup tuning recommendations

OpenDedup tuning recommendations

OpenDedup has a flexible design which can span from small users to large data enterprises. You can tune OpenDedup as per your requirements to serve your use-case. Veritas recommends that you perform the following tuning before you start using the LTR solution.

Table: XML tags

XML parameter

Value

max-open-files

200

write-threads

32

io-threads

64 (within extended config)

map-cache-size

1024

local-cache-size

500 GB (as per your local cache)

sync-on-write

false

refresh-blobs

true (only to be set when Glacier cloud tier is used)

glacier-archive-days

30 (only to be set when Glacier cloud tier is being used)

sync-files

true (within extended config)

chunk-size

40960

hash-type

VARIABLE_MD5

max-file-writebuffers

80

On the media server for the ODD-on-Media_Server use case:

# echo "* hard nofile 65535" >> /etc/security/limits.conf
# echo "* soft nofile 65535" >> /etc/security/limits.conf
# exit

Based on the system workload, ensure that the number of portal threads are increased (on Veritas Access): 

/opt/VRTSnas/conf/portald.conf >> cf_max_s3_threads
