Your LaCie 5big NAS Pro optimizes disk performance and capacity using LaCie SimplyRAID. No matter the capacity of your disk(s), LaCie SimplyRAID will prepare the LaCie 5big NAS Pro storage for immediate use as well as future expansion. LaCie SimplyRAID accommodates your storage needs, allowing you to:
While LaCie recommends the benefits of LaCie SimplyRAID, the Dashboard RAID page also gives you the option to manually configure RAID.
See RAID Status: Expand, Replace, and Reset for instructions on expanding your array and replacing disks.
Factors that determine available data capacity include:
Refer to the table below for an overview of the different RAID modes, and see the descriptions for details. Note that this information is summarized in the RAID Setup Wizard on the Dashboard.
|RAID Mode||Minimum Hard Drives||Data Capacity||Protection||Performance||Factory Default|
|RAID 5||3||60% - 75% (estimate varies by disk configuration)||–|
|RAID 6||4||60% (estimate varies by disk configuration)||–|
Follow the directions to run the RAID Setup Wizard. You may select:
Rebuilding a protected RAID array can take many hours, depending on the capacity of the hard disks and your LaCie NAS's available resources (concurrent tasks such as backups or torrent downloads will slow rebuilding). Changing to an unprotected RAID mode (e.g. RAID 0) takes less than five minutes. Note that data is accessible during rebuilding.
The RAID Status box will inform you of changes to your array that may require action on your part. Follow the instructions below to:
Unprotected RAID Arrays and Swapping/Expanding Hard Disks:
Protected RAID Arrays and Swapping/Expanding Hard Disks: If your array is protected (e.g. RAID 1), you can remove a hard disk while the product is turned on without damaging the array and losing data, a process also referred to as “hot-swapping”. In most instances, LaCie recommends hot-swapping when replacing or expanding hard disks in the LaCie NAS. For example, if you swap or insert unclean hard drives (with data) from another LaCie NAS (e.g. a LaCie 2big NAS to a LaCie 5big NAS Pro), you may experience problems when first booting your current LaCie NAS.
When replacing or expanding hard drives in a protected RAID array:
If you have configured your RAID as Standard (Manual as opposed to SimplyRAID), the new disk must have equal or greater capacity than the disk it is replacing.
The Dashboard will become unavailable for a brief period of time as the system configures the RAID. On protected RAID arrays, you may continue to access files stored on your LaCie NAS during the RAID synchronization.
If a hard drive in the array fails and you do not have a replacement disk, you can use the Reset button to reconfigure the RAID. The Reset button will optimize the RAID configuration using the remaining disks. LaCie recommends that you back up your files since all data will be deleted while creating the new RAID array.
