RAID Introduction - Practice part
A common real-life situation is when a client brings in a disk set, but not the device the disks were originally in.
Routine process is then to identify the controlling device, be it a NAS or a RAID controller,
and figure as much as possible from the device documentation. This is done simply by using Google.
With any type of device you can get at least:
- maximum possible number of disks connected,
- list of supported RAID levels,
- hotspare capability when applicable.
With a NAS, you can additionally get at least:
- software RAID layout in use,
- list of possible filesystem types.
Plus, whatever additional information might be available is also great.
The identification is typically done by a photo or by having customer read everything printed on the device over the phone.
The following two tasks do not require anything special and take maybe ten minutes each.
Task 1 - Identify device by photo
Identify and collect as much as possible information about this device (click image for full size).
Task 2 - Identify device by partial label
Identify and collect as much as possible information about a "black box" which has the following two labels on it:
"LS-WXL series", "LS-WXZ.OTL".
