Oracle’s Sun Storage Archive Manager – optimized solution for lifecycle content

Mittwoch, Juni 29th, 2011

oracle_logo.jpg   Oracle´s Sun Storage Archive Manger is a proven solution for PACS systems and medical records or documents. This requires securely storing and accessing documents and records from multiple sources. Retention is the life of the patient plus several years. Comparison of archived records with current results is ongoing throughout the life of the patient

Solaris 10 / SUN SamFS 4.6 – Working with SamFS / Adding Devices to a Storage Pool

Donnerstag, Januar 1st, 2009

dynamically add space to a pool by adding a new top-level virtual device. This space is immediately available to all datasets within the pool. To add a new virtual device to a pool, use the „zpool add“ command

# zpool add samfs2_pool_1 c2t3d0
# zpool add samfs2_pool_2 c2t4d0

# zpool status samfs2_pool_1
pool: samfs2_pool_1
state: ONLINE
scrub: none requested

samfs2_pool_1 ONLINE 0 0 0
c2t1d0 ONLINE 0 0 0

# zpool status samfs2_pool_2

Solaris 10 / SUN SamFS 4.6 – Working with SamFS / Planning Issues for the Recycling Process

Donnerstag, Januar 1st, 2009

Recycling is the process of reclaiming space on archive volumes. The recycler works with the archiver to reclaim the space occupied by unused archive copies. As users modify files, the archive copies associated with the old versions can be purged from the system

# cat /etc/opt/SUNWsamfs/archiver.cmd
interval=2m
fs = samfs1
logfile=/var/opt/SUNWsamfs/archiver/samfs1.log
arset1_dir01 dir01
1 30s
2 120s

arset1 .
1 30s
2 1200s

params
allsets -recycle_hwm 50 -recycle_mingain 50 -recycle_vsncount 1
endparams

vsns
arset1.1 dk disk11
arset1.2 dk disk21
arset1_dir01.1 dk disk12
arset1_dir01.2 dk disk22
samfs1.1 dk disk10
endvsns

-recycle_hwm 50 „high water mark “ – Percentage of the total storage space in the library that must be utilized before recycling will occur

-recycle_mingain 50 „minimum gain“ – Percentage of the VSN that must be expired archives before it can be recycled

-recycle_vsncount 1 – „VSN count“ – Maximum number of VSNs recycled in one recycler run

Creating a crontab File for the Recycler If the system is performing as expected, you are ready to make a crontab entry for the superuser to run the recycler periodically, every two hours or more, depending on your site’s conditions

# EDITOR=vi
# export EDITOR
# crontab -e
