The Adaptec PCI-X zero-channel RAID
(ZCR) card offers the ideal solution for
customers who want an affordable, flexible
upgrade path to advanced RAID. The
Adaptec SCSI RAID 2020ZCR and
2025ZCR cards provide an affordable, high-
performance solution to businesses
requiring data protection. The low profile
form factor is ideal for workstations and
high-density server environments.
The Adaptec SCSI RAID 2020ZCR and
2025ZCR cards take advantage of the
system motherboard’s existing UltraU320
SCSI I/O channels by using complementary
logic designed on the motherboard. This
innovative approach reduces the cost of the
RAID card by eliminating the need for a
SCSI I/O chip on the card. The Adaptec
2020ZCR and 2025ZCR cards offer high-
speed throughput, scalability, space-saving
features, and a cost-effective upgrade path
to a full-featured PCI-X RAID solution.
Configuration and Interoperability
The Adaptec 2020ZCR requires
motherboards with a 64-bit PCI/PCI-X slot
supporting Adaptec Embedded RAID Logic
(EMRL) or Intel RAIDIOS Logic.
The Adaptec 2025ZCR is a “credit card size”
RAID card that plugs into a specially
designed small form factor PCI-X
connector (an SODIMM connector
attached to the PCI-X bus via EMRL) on
Ultra320 motherboards. This unique design
gives high-density servers advanced RAID
protection and performance without
sacrificing a PCI-X slot, making it ideal for
1U applications.
Easy-to-use storage management
The Adaptec 2020ZCR and 2025ZCR
operate under Adaptec Storage Manager
™
, a
storage management tool that centralizes
management of all Adaptec host-based and
all hardware based RAID products. The
software enables remote management,
monitoring, and configuration of RAID
arrays through secure, encrypted remote
communications. The intuitive RAID
management tool provides pop-up tips and
online help to simplify the creation and
management of RAID arrays.
Compatibility, Reliability, and Support
Adaptec zero-channel RAID cards are
designed to work with motherboards
incorporating a complementary logic, such
as Adaptec Embedded RAID logic (EMRL)
or Intel RAIDIOS logic. Like all Adaptec
products, the Adaptec SCSI RAID ZCR
cards have been extensively tested with
third-party systems and SCSI devices to
deliver the utmost in compatibility, now
and in the future. They are backed by a 3-
year warranty and industry leading Adaptec
technical support.
