Memory

In the past, Random Access Memory (RAM) was very expensive and admins were tightly constrained by budget and server slots when provisioning out infrastructure. Today's technologies, however, afford us very large capacity modules and sufficient slots to often provision as much as a terabyte (TB) or even more for each server.

Ceph components vary in their memory needs; in this section, we'll help you chose the right size for your servers to fulfill both operational and financial goals.
