Technology and architecture of HP ProLiant AMD-based 100 - series G6 (Generation 6) servers
supports limited configurations. 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 memory module that can significantly increase performance.
ZMR is supported on present generation Smart Array controllers for internal, direct connections only.
This includes the Smart Array P212 supported in the ProLiant DL165 G6 server. Modular Smart Array
(MSA) products are not supported in ZMR mode.
HP Smart Array controller compatibility
HP Smart Array controll
ers are modular solutions with a common form factor, hardware, and
firmware. The present generation of SAS/SATA based Smart Array controllers are compatible with
ProLiant AMD 100-series G6 servers. The ProLiant DL165 G6 server is available as a non-hot plug
SATA hard drive model, or as a hot plug SATA/SAS hard drive model. The non-hot plug SATA model
uses an HP embedded SATA controller and does not support RAID configurations. The hot plug
SATA/SAS model uses an HP Smart Array P212 controller. Zero Memory RAID (ZMR) is available as
an entry level, hardware based RAID solution, but users have the option to choose the cache size and
to include the BBWC. These options facilitate upgrades from ZMR to 512 BBWC.
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. SAAP is
hosted on the Smart Array controller hardware firmware stack. It can be enabled beginning with the
new generation of Smart Array controllers released in the first half of 2009.
SAAP requires a license key for activation. After activation, administrators can use several standard
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.

NOTE:
At a minimum, a 256 MB cache and battery kit is required to enable the
SAAP license k
ey. SAAP is not available on Zero Memory Configurations
