Consider the following physical storage elements before you decide how to distribute data across the available physical storage:
- Trays hold the disk drives and support their operation. Each tray holds up to 14 disk drives.
- Disk drives are nonvolatile, randomly addressable, rewriteable data storage devices.
- Initiators are Fibre Channel (FC) ports on host bus adapters (HBAs) that allow hosts to gain access to a storage array.
- Hosts, or data hosts, are servers that can store data on a storage array. Data hosts are mapped to initiators.
- A host group is a collection of one or more hosts on one storage array that share access to the same volumes.
