Broadcom RAIDCore Controller Cards Achieve Unprecedented 1 Gigabyte Per Second13 January 2005
This unprecedented performance achievement establishes the
BC4000 controller card family as the new technological benchmark for RAID
throughput and performance. Broadcom announced these test results today for
RAID0 sequential reads and writes, and RAID50 sequential reads, following the
recent completion of an independent benchmarking review from respected
industry review resource Tom's Hardware Guide, which completed its own
32-drive performance test using RAIDCore BC4852 controllers.
With the increasing use of RAID technology as the cornerstone for data
storage and integrity for large databases, and with the increasing popularity
of cost-sensitive digital media applications with large storage demands, the
need for improved and more affordable RAID performance has become critical.
To answer this need, Broadcom's RAIDCore BC4000 controller cards were
developed to combine its enterprise-class XelCore(TM) RAID software with its
BCM5770 SATA controller chip to offer affordable RAID technology that sets new
benchmarks in industry performance.
Broadcom recorded actual transfer rates for sequential RAID0 reads and
writes of 1.0 GB/s and 1.3 GB/s respectively, and sequential RAID50 reads and
writes of 1.3 GB/s and 310 MB/s respectively. This is the first time that a
performance level over one Gigabyte per second was achieved using SATA-based
RAID controller technology.
The test was conducted in a controlled environment using four RAIDCore
BC4852s (8-channel) RAID controllers and thirty-two 80GB Hitachi Deskstar(R)
SATA drives running on a server with a Super Micro(TM) X5DPE-G2 motherboard
and a 2.8 GHz Intel XEON(R) x2 processor. A single array of 10 Gigabytes was
created using Broadcom's popular XelCore RAID software stack and controller
spanning -- an XelCore feature that allows data arrays to span disks attached
to different controllers. The standard Iometer test program (2003.05.10) was
also used as part of the benchmark. Once Broadcom completed the test and
verified its breakthrough performance, the benchmark results were then
substantiated by Tom's Hardware Guide which concluded, "There is no faster
way." The results of this test are available online at http://www.tomshardware.com.
"We consider the Broadcom RAIDCore RAID controller card family to be the
price/performance leader," said Tony Asaro, Senior Analyst for the Enterprise
Strategy Group. "The controller cards are easy to use, provide a rich feature
set, offer incredible performance and the price is extremely attractive.
Broadcom is poised to be an industry leader in this space based on its
RAIDCore product family and is an excellent solution for small-to-medium
businesses and cost-conscious customers."
"Controller spanning enables superior storage performance and enterprise-
class features on industry standard server platforms," said Shriraj Gaglani,
Director of Storage Marketing for Broadcom's Storage Line of Business.
"Customers with IT budget constraints can now scale their storage capacity and
reliability while using cost-effective, easy-to-use SATA storage."
Broadcom's RAID technology is designed for wide scale adoption in the
industry based on the most extensive and robust set of enterprise-class
storage and data integrity features available to all levels of businesses.
Through its unique Fulcrum(TM) architecture, enterprise-class XelCore RAID
software, and the emergence of low cost and high capacity SATA drives,
Broadcom is able to offer enterprise-level features without the cost and
IT-intensive processes that have kept RAID from being more widely used. It
also brings to market a set of enterprise-class RAID storage solutions to
existing Broadcom customers in the high-volume server and storage markets.
