Configuring Your Controller

86 3ware SATA+SAS RAID Controller Card Software User Guide, Version 10.0

Setting the Size of Volumes Created with

Auto-Carving

You can use auto-carving to divide units larger than 1 TB into multiple

volumes. You control the size of the volumes to be created by setting the carve

size (referred to as carving factor in 3BM). The carve size can be between

1TB (1024 GB) and 32 TB (32768 GB); the default is 2 TB.

When you change this policy, it applies to units you create in the future.

Existing units will not be affected.

To set the carve size in 3DM 2

1 Choose

Management > Controller Settings from the menu bar in

3DM 2.

2 In the Other Controller Settings section at the bottom of the screen, in the

Carve Size field, enter the size you want (between 1024 GB and

32768 GB) to use and click

Submit.

The page refreshes, and a message at the top confirms the change you

have made.

To set the carve size (carving factor) in 3BM

1 On the main 3BM screen,

Tab to Settings and press Enter.

2 On the pop-up menu, select

Controller Policies and press Enter.

3 On the Policy Settings page,

Tab to the Carving Factor field, press Enter

to display the text entry box, enter the size you want (between 1024 GB

and 32768 GB) and press

Enter again to accept it.

Tab to OK and press Enter to select it.

The policy is enabled immediately.

Enabling and Setting Up Staggered Spin-up

You can set the number of SAS and SATA drives that will spin up at the same

time and the delay time between drive group spinups. This does not apply to

SAS or SATA drives that are attached to an expander.

Three policy settings let you set the number of drives that will spin up at the

same time and set the delay between drive groups that spin up at one time.

Not all SATA drives support staggered spinup. If you enable staggered spinup

and have drives that do not support it, the setting will be ignored. You can

change these settings in 3BM or using the CLI.
