OceanStor Dorado2100 G2
Huawei OceanStor Dorado2100 G2 (the Dorado2100 G2
for short) is a SAN-based solid state storage
product designed for the enterprise-level
high-performance storage market. The Dorado2100 G2
uses a full-SSD architecture and employs advanced
cache management and I/O scheduling mechanisms. It
offers an ideal choice for various
performance-demanding storage scenarios such as
large databases, VDIs, and high-performance
computing.
Product Features
Outstanding Performance
High IOPS: The Dorado2100 G2 delivers a
superb performance of up to 600,000 IOPS, which
is equivalent to the performance of a
traditional disk array consisting of 1,500 15K
rpm SAS disks.
Excellent responsiveness: The access latency
is as low as 500μs, which is only 5% of that
with traditional disk arrays.
Reliability
Dual-controller architecture: The
active-active dual controllers implement
redundancy and load balancing, ensuring high
service reliability.
Component redundancy design: Redundant power
supplies, fans, controllers, interface modules,
SSDs, and BBUs eliminate single points of
failure while supporting hot-swap and online I/O
expansion.
Comprehensive media protection: The adopted
wear leveling, bad block repair, and random
scrambling code technologies can dramatically
prolong the service life of storage media with a
global MTBF greater than one million hours.
Comprehensive system protection: The
Dorado2100 G2 supports or presents RAID 0, 5,
and 10, global hot spare disks, and data
pre-copy for faulty disks.
Economy and Efficiency
Low power consumption: The typical 580 W
system power consumption saves power up to 90%
compared with performance-equivalent traditional
disk arrays.
Small footprint: Compared with traditional
disk arrays, the Dorado2100 G2 saves 95% of
cabinet footprint but has the same performance,
dramatically reducing the cabinet purchasing
cost.
Intelligent thin provisioning: The automatic
capacity expansion function improves disk
utilization and implements on-demand disk
purchasing, reducing the initial purchasing
cost.
Ease of Use
Simplified management: The user-friendly
management and maintenance mechanisms support
GUI and CLI modes and provide alarm notification
by sound, short message, and email.
Intelligent service life monitoring for
SSDs: The Dorado2100 G2 constantly monitors the
operating status of SSDs and notifies exceptions
detected in real time, helping ensure
application reliability.
Easy deployment: The Dorado2100 G2 uses a
standard SAN form without changing existing IT
architecture and protects the original
investment.
