The FBWC DDR2 mini-DIMM cache module is specifically designed for the present generation of
PCIe2.0, SAS-based Smart Array controllers based on the PMC PM8011 SAS SRC 8x6G RAID on a
chip (RoC). The primary FBWC components consist of the cache module, Super-caps with integrated
charger, and RoC located on the system board.
At the time of this writing, the FBWC cache is supported on the Smart Array P410, P410i, P411,
P212, P812, and P712m.
For more information on the flash-backed write cache, see the “HP Smart Array Controller technology
brief” at

Zero Memory RAID
Using Ze
ro Memory RAID (ZMR), administrators can create a RAID 0-1 configuration without
additional memory. Smart Array P410, P411, and P212 controllers include ZMR. The P212 controller
does not include ZMR on the external connector. ZMR supports up to eight drives in Zero Memory
Mode, or seven drives and one tape drive. ZMR does not include caching; however, all systems can
be upgraded to a BBWC or FBWC memory module that can significantly increase performance.
NOTE:
Smart Array Advanced Pack is not available on Zero Memory configurations.
Smart Array Advanced Pack
HP Smart Array Advanced Pack (SAAP) firmware provides advanced functionality within Smart Array
controllers. This firmware further enhances performance, reliability, and data availability. The Smart
Array controller hardware firmware stack supports SAAP. It can be enabled on the P212, P410,
P410i, and P411 controllers.
SAAP requires a license key for activation. After activation, administrators can use several
capabilities:
• RAID 6 with Advanced Data Guarding (ADG) protects against failure of any two drives. It requires
a minimum of four drives, but only two will be available for data. ADG can tolerate multiple
simultaneous drive failures without downtime or data loss and is ideal for applications requiring
large logical volumes, because it can safely protect a single volume of up to 56 disk drives. RAID
ADG also offers lower implementation costs and greater usable capacity per U than RAID 1.
• RAID 60 allows administrators to split the RAID storage across multiple external boxes. It requires a
minimum of eight drives, but only four will be available for data.
• Advanced Capacity Expansion (ACE) automates higher capacity migration using capacity
transformation to remove logical drives by shrinking and then expanding them online. Standard
drive migration and expansion remain unchanged.
• Mirror Splitting and Recombining in Offline Mode breaks a RAID 1 configuration into two RAID 0
configurations. This is similar to a scaled down rollback functionality that requires two disk drives.
• Drive Erase completely erases physical disks or logical volumes. This capability is useful when
decommissioning, redeploying, or returning hard drives.
• Video On Demand Performance Optimization decreases latency and improves video streaming.
