Hybrid RAID 1 & 10: SSD +
HDD for Maximum Performance
and Reliability
>
Adaptec Series 2 Unied Serial RAID controllers
are designed to support hardware RAID 0, 1, 10
and JBOD while oering direct I/O connectivity
for SATA/SAS tape devices and hard disk drives.
Equipped with an industry-leading dual core
RAID on Chip (ROC), this family oers 128MB
of DDR2 533MHz write cache and supports up
to 128 devices using SAS expanders. ey
oer an x8 PCI Express host interface bus
connection in a low-prole MD2 form factor.
Series 2 controllers oers high bandwidth for I/O
applications and at the same time basic hardware
RAID functionality that is fully independent of
the host and operating system and compatible
with other Adaptec RAID controller families.
Hybrid RAID
With Hybrid RAID 1 & 10 the Series 2 controllers
oer 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 oers the benets of both technologies
and allows a better cost per GB ratio than
comparable SSD-only RAID arrays.
The Case for Cache
e fastest way for a RAID controller to fulll
a read or write request is to serve data out of its
cache. Enabling the RAID controller cache oers
signicant performance benets, such as reduced
latency in I/O requests, bandwidth and queue
depths that surpass soware application limits,
and on-the-y parity calculations on sequential
writes.
Intelligent Power Management
e power required by disks is a primary
ongoing storage cost. Full power is maintained
to every disk whether it is actively being used or
not, which also increases cooling costs. Adaptec
Intelligent Power Management slashes power
and cooling costs by spinning down idle disks
and providing a lower power mode for active
disks.
One-view Storage Management
Adaptec Storage Manager™, a one-view tool
centralizes management of all Adaptec RAID
products.
Broad Operating System Support
Extensive operating system support includes
all major soware releases, such as Windows,
Linux, FreeBSD, and UNIX variants.
Compatibility, Reliability, and Support
e Series 2 family has been extensively tested
with third-party components to deliver the
utmost in compatibility. e cards are backed
by a 3-year warranty and the company’s
legendary technical support.
