Adaptec 6405 Datasheet

Adaptec 6Gb/s SATA & SAS RAID Family
with Intelligent Power Management & Zero-Maintenance
Cache Protection (6405, 6445, 6805)
Unified Serial (SATA/SAS) 6Gb/s RAID Controllers Deliver Superior Bandwidth
®
and Reliability, Energy Efficiency and Operating Costs Savings
Adaptec Series 6 RAID controllers feature PMC-
Sierra's market-leading, multi-core SRC 8x6G
RAID-on-Chip (ROC), 512MB DDR2 667MHz
cache, and an x8 PCI Express Gen2 host bus
connection. They support up to 256 SATA/SAS
devices and feature Adaptec Intelligent Power
Management for improved energy-efficiency, plus
Zero-Maintenance Cache Protection (ZMCP —
pronounced "zemcap") to help data centers save
thousands of dollars in operating costs.
Highest Performance
Series 6 controllers deliver up to 60% higher
sustained sequential throughput than previous
generation Adaptec controllers and up to 2GB/s
sustained data transfer rate to the host. At peak
performance, Series 6 offers 4.8GB/s through the
SAS 2.0 interface and 4.0GB/s through the PCI
Gen 2 host interface.
Advanced Data Protection
Adaptec RAID Code (ARC) delivers maximum
reliability with RAID levels 0, 1, 1E, 5, 5EE, 6, 10,
50, 60 and JBOD. ARC also offers RAID Level
Migration (the ability to easily migrate RAID
levels), Online Capacity Expansion (expand
capacity without powering down the server),
and Copyback Hot Spare (when a failed drive has
been replaced, data is automatically copied from
the hot spare back to the restored drive).
Hybrid RAID
With Hybrid RAID 1 & 10 the Series 6 controllers
offer maximum performance and reliability
by combining Solid State Drives (SSDs) and
Hard Disk Drives (HDDs) in a single array. By
performing read operations from the faster SSD
and write operations on both the SSDs and HDDs
the result is tremendous performance gains over
standard HDD RAID arrays. Hybrid RAID offers
the benefits of both technologies and allows a
better cost per GB ratio than comparable SSD-
only RAID arrays.
The Case for Cache
The fastest way for a RAID controller to fulfill
a read or write request is to serve data out of
its cache. Savvy network administrators know
that enabling the RAID controller cache offers
significant performance benefits, such as reduced
latency in I/O requests, bandwidth and queue
depths that surpass software application limits, and
on-the-fly parity calculations on sequential writes.
Zero-Maintenance Cache Protection
RAID controllers typically employ battery backup
units (BBUs) to protect cached data during power
loss, but BBUs require constant monitoring and
preserve data for a maximum of 72 hours during
power loss. Series 6 controllers introduce Zero-
Maintenance Cache Protection, a revolutionary
advancement that solves BBU deficiencies by
providing full protection to cached data with no
installation, monitoring, maintenance, disposal,
or replacement costs.
Featuring 4GB of SLC based NAND flash memory
with super capacitor technology (available as a
separate Kit), Series 6 controllers instantly save
cache contents in the event of system power loss.
On a power failure, the data is copied from the
high performance DRAM cache of the controller
to the NAND flash memory while the super
capacitor provides enough energy to support this
process and power the controller for approximately
60 seconds. Unlike a BBU, the data is protected for
years when copied to the flash memory.
Intelligent Power Management
Intelligent Power Management (IPM) slashes
power and cooling costs by up to 70% using
intelligent I/O caching combined with disk drive
power savings via standby and power-off modes.
One-view Storage Management
The Series 6 family operates under Adaptec
Storage Manager™, a one-view tool that centralizes
management of all Adaptec RAID products.
Broad Operating System Support
The Series 6 family supports all major operating
systems, including Windows, Linux, VMware and
FreeBSD.
Compatibility, Reliability, and Support
The Series 6 family has been extensively tested
with third-party components to deliver the utmost
in compatibility. The cards are backed by a 3-year
warranty and the company's legendary technical
support.
