Advantage
Key Features
HP's innovative design and integration work of the Smart Array family of products creates customer value
that is unmatched in the industry. Use of Smart Array products across multiple applications results in a
much lower Total Cost of Ownership (TCO) than any other server storage RAID product. The HP Smart Array
family brings an unparalleled return on investment through:
Data Compatibility among most current shipping Smart Array controllers allows simple and easy
upgrades any time needs for higher performance, capacity, and availability increase. Even successive
generations of Smart Array controllers understand the data format of other Smart Array Controllers.
Consistent Configuration and Management Tools. Most current shipping Smart Array products utilize a
standard set of management and utility software. These tools minimize Total Cost of Ownership (TCO) by
reducing training requirements and technical expertise necessary to install and maintain the HP server
storage.
SmartDrive Carrier form factor is for use across multiple HP servers, Universal Hard Drive form factor is
for disk enclosures and storage systems. With compatibility across many enterprise platforms, you are
free to deploy and re-deploy these drives to quickly deliver increased storage capacity, migrate data
between systems, and easily manage spare drives.
Pre-Failure Warranty means HP Insight Manager not only reports when a drive is going to fail but allows
replacement of failing drives prior to actual failure. For complete details, consult the HP Support Center or
refer to your HP Server documentation.
The SA-P420 Controller supports up to 27 drives depending on the server implementation.
Seamless upgrades from past generations and upgrades to next generation HP high performance
and high capacity Serial Attached SCSI Smart Array controllers.
6Gb/s SAS technology delivers high performance and data bandwidth and contains full compatibility
with 6Gb/s SATA technology.
x8 PCIe 3.0 host interface technology delivers high performance and data bandwidth up to 8 GB/s
maximum bandwidth.
Modular, easy-to-upgrade design lets you optimize performance by upgrading from 40-bit 512MB
cache to 72-bit 1GB Flash Backed Write Cache or 72-bit 2GB Flash Backed Write Cache (FBWC).
Addition of the flash backed cache upgrade enables array expansion, logical drive extension, RAID
migration, and stripe size migration.
Standard on the P420 are RAID 6 ADG, RAID 60 ADG, RAID 1 ADM, Capacity Expansion, mirror split,
recombine, and rollback in Online Mode, Drive Erase, Performance Optimization-Degraded Reads
and Read Coalescing, Move/Delete any individual LUNS and Online Split Mirror
The HP SSD Smart Path feature included in the Smart Array software stack improves SSD read for all
RAID levels and RAID 0 write operations by optimizing the path to each SSD attached to the
controller
The HP SmartCache licensed feature (available as an additional option) is a controller-based read
caching solution in a DAS environment that caches the most frequently accessed data ("hot" data)
onto lower latency SSDs to dynamically accelerate application workloads.
Mix-and-match SAS and SATA hard drives, lets you deploy drive technology as needed to fit your
computing environment.
Software consistency on most current shipping Smart Array products: HP Smart Storage
Administrator, HP Systems Insight Manager (SIM), and Intelligent Provisioning.
Low-profile PCI Express form factor - ships with a full size bracket for deployment in either a low-
profile or full sized slot.
