OpenDedup tuning recommendations

OpenDedup has a flexible design that works for small users as well as 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
