Netgear RD5200 (ReadyDATA 5200) – ReadyDATA 5200 System Empty Chassis with 10G (2 port SFP+ card) ソフトウェアガイド

Logbias

Change the logbias setting by making a selection from the Logbias drop-down list:

Latency. Data requests are handled at high priority with a minimum of delay, but data 
throughput might not be optimum, the default setting that is automatically assigned 
when you create a share.

Throughput. Data requests are handled with high data throughput, but there might be 
delay in response to requests.

Sync Writes

Change the setting by making a selection from the drop-down list:

Allowed. 

Forced. Synchronous writes are required.

Disabled. Synchronous writes are not used.

Compression

Select the Compression check box to enable data compression. Compression saves 
storage space and increases the speed of data transfers, but the compression and 
decompression processes require more resources. 

Dedupe

Select the Dedupe check box to enable deduplication, which prevents storage of redundant 
data on the share. Unique data is stored only once on the share, and other instances of the 
identical data are removed and replaced by a pointer to the unique data. This storage 
method saves storage space and increases the speed of data transfers. By default, the 
Dedupe check box is cleared.

You can enable deduplication for a thin LUN but not for a thick LUN.

NETGEAR does not recommend enabling deduplication for performance-sensitive 

data on applications such as virtual machines and databases.

Provision

Select Convert to change the provisioning, thick to thin, or thin to thick. When you select 
Convert, a confirmation screen opens. Click the Yes button, to confirm.

Size 

113.

Continuous 
Protection

Select the Continuous Protection check box to enable data protection through snapshots 
and configure the frequency at which snapshots are made. By default, the Continuous 
Protection check box is selected. For more information about snapshots, see 

Smart 
Snapshot 
Management

Select the Smart Snapshot Management check box to enable automatic 
snapshot pruning. When enabled, the ReadyDATA deletes older snapshots 
so that hourly snapshots are kept for 48 hours, daily snapshots are kept for 
four weeks, weekly snapshots are kept for eight weeks, and monthly 
snapshots are kept indefinitely. 

For shares or LUNs that were created before the release of this 

feature, Smart Snapshot Management is disabled by default.

Interval

The interval specifies how often a snapshot is made. Make a selection from 
the drop-down list:

Hourly. A snapshot is taken every hour on the hour.

Daily. A snapshot is taken every day at midnight, the default setting.

Weekly. A snapshot is taken every week on Friday at midnight.
