Doc Text The autoscaler is back to a `scale-up` profile by default,
where it starts out each pool with minimal PGs and scales
up PGs when there is more usage in each pool. However, it also has
a `scale-down` profile, where each pool starts out with a full complements
of PGs and only scales down when the usage ratio across the pools is not even.

With only the `scale-down` profile, the autoscaler identifies
any overlapping roots and prevents the pools with such roots
from scaling because overlapping roots can cause problems
with the scaling process.

.The autoscaler is set to scale-up by default in {storage-product} 5.1

With this release, the autoscaler is set to scale-up by default where it starts out each pool with minimal placement groups (PGs) and scales up PGs when there is more usage in each pool.

There is also a scale-down profile, where each pool starts with compliments of PGS and only scales down when the usage ratio across the pools is not even. In a scale-down profile, the autoscaler identifies any overlapping roots and prevents the pools with such roots from scaling because overlapping roots can cause problems with the scaling process.

With this release, the autoscaler is set to scale-up by default where it starts out each pool with minimal placement groups (PGs) and scales up PGs when there is more usage in each pool.

There is also a scale-down profile, where each pool starts with ideal full-capacity PGs and only scales down when the usage ratio across the pools is not even. In a scale-down profile, the autoscaler identifies any overlapping roots and prevents the pools with such roots from scaling because overlapping roots can cause problems with the scaling process.
