Entries in this table define entities (buffer pools
in this case) which are contained in an entity 
(memory pool) defined by an entry from
cempMemPoolTable.
-- Basic Pool Architecture --
1)Pools are classified as being either Static or 
  Dynamic. Static pools make no attempt to increase 
  the number of buffers contained within them if the 
  number of free buffers (cempMemBufferFree) are less
  than the number of minimum buffers (cempMemBufferMin).
  With Dynamic pools, the pool attempts to meet the 
  demands of its users.
2)Buffers in a pool are classified as being either 
  Permanent or Temporary. Permanent buffers, as their
  name suggests, are always in the pool and are never
  destroyed unless the number of permanent buffers 
  (cempMemBufferPermanent) is changed. Temporary
  buffers are transient buffers that are created in
  dynamic pools whenever the free count 
  (cempMemBufferFree) of buffers in the pool drops 
  below the minimum (cempMemBufferMin).
3)Buffers pools are classified as either Public or 
  Private. Public pools are available for all users 
  to allocate buffers from. Private pools are
  primarily used by interface drivers.

A table that lists the cache buffer pools
configured on a managed system. 
1)To provide a noticeable performance boost, 
  Cache Pool can be used. A Cache Pool is effectively
  a lookaside list of free buffers that can be 
  accessed quickly. Cache Pool is tied to Buffer Pool. 
2)Cache pools can optionally have a threshold value
  on the number of cache buffers used in a pool. This
  can provide flow control management by having a 
  implementation specific approach such as invoking a
  vector when pool cache rises above the optional 
  threshold set for it on creation.
