Avoid Practices—LFF Drive Allocating and Loading Guidelines
When allocating and loading drives in enclosures, the following are the Hewlett Packard
Enterprise recommended avoid practice guidelines:
Avoid leaving any empty slots between drives.
Avoid an unbalanced number of same type drives.
Avoid mixing HDD and SSD drive types in the same column.
Avoid filling an entire drive enclosure when additional enclosures are available. Leaving
empty slots in each enclosure allows for future upgrade flexibility to add a new drive type
and license features.
Avoid Practices—Example
Avoid loading the LFF drives in the following manner, because this example demonstrates an
unbalanced load, due to the NL drives being installed across all four columns. Instead, the drives
should have been loaded in the first column before moving to the next column to the right.
