The RamSan-5000 is a scalable
enterprise data storage solution based on the award-winning
RamSan-500 Cached Flash Solid State Disk (SSD). The RamSan-5000
is the fastest Flash memory-based system in the world to go
beyond the lab and into the marketplace. The base-line
configuration delivers one million Input/Output operations Per
Second (IOPS) and can scale to several million IOPS using Texas
Memory Systems� new Turbo feature.
The RamSan-5000 solution is an
array of ten (10) individual RamSan-500 Cached Flash units. The
systems are deployed with Texas Memory Systems TeraWatch
firmware which supports monitoring and configuration of the
units from a single graphical user interface.
Solid state disk systems are used
by large enterprise, government, military, and research
organizations to accelerate their most critical applications.
Faster systems can support more transactions and users with
fewer servers and licenses. As such they are more cost effective
than adding large hard-disk based systems, server-based RAM, or
expensive application tuning. Flash-based SSD systems like the
RamSan-5000 offer dramatically lower costs and power consumption
than previously available.
Customers with high performance
storage needs expect to pay high prices for effective storage
solutions, but the RamSan-5000 changes the rules. When modest
performance requirements are added to the cost of raw capacity,
RamSan-5000 solutions become cost competitive with traditional
high performance hard disk drive (HDD) storage arrays. As the
performance requirements escalate, so do the cost advantages of
the RamSan-5000. Even at only moderately high performance
requirements, solution costs drop to a fraction of the initial
purchase price of equivalent HDD storage systems, with on-going
power, space, and administration savings as added benefits.
Texas Memory Systems� Turbo
feature allows users to lock a logical unit (LUN) of storage in
the large RAM cache of the predominantly Flash-based RamSan-500
units that make up the RamSan-5000 solid state system. Turbo
transitions the RamSan system into a self-contained tiered
storage solution with frequently-accessed files placed in
persistent RAM storage while the remaining files are stored in
Flash. A single RamSan-500 with the Turbo feature can provide
over 300,000 random IOPS based on a mixture of accesses to the
locked LUN and Flash memory. Therefore, a RamSan-5000 comprised
of 10 Turbo-enabled RamSan-500s offers several million random
IOPS.
- The World's Fastest Storage�
- Cached Flash RAID for the
Enterprise
- 1,000,000 random I/Os per
second sustained (reads from Flash)
- 10TB to 20TB Flash RAID
- 160GB to 640GB DDR Cache
- 20 GB/s sustained bandwidth
(to Flash)
- Full array of hardware
redundancy to ensure availability.
The RamSan-5000 addresses the
needs of commercial, private, and governmental enterprises
relying on mission critical applications with performance and
highly scalable data storage requirements. It provides the best
price per performance availible on the market today.
The RamSan-5000 is available with
20TB of RAID-protected Flash, up to 640GB of RAM cache, and up
to 80 4Gbit Fibre Channel ports (or 40 4x InfiniBand ports). It
can deliver over 1,000,000 random read IOPS and up to
20GB/second of read or write bandwidth. Texas Memory Systems
RamSan-5000 systems serve a range of enterprise requirements,
including storage for large OLTP systems or data warehouses,
video on demand, rendering, geospatial analysis, seismic
processing, and data acquisition. The unique combination of
cache to accelerate writes and Flash to accelerate reads results
in a system truly balanced for enterprise applications. The
20TB RamSan-5000 is a proven solution and has already been
installed at a customer site.
When performance is a factor, the
RamSan-5000 offers power and density advantages over HDD-based
storage media. The RamSan-5000 uses only 3,000 watts to deliver
1,000,000 IOPS. Deploying a disk based system with similar
performance would require 5,000 HDDs and consume over 90,000
watts. The RamSan-5000 uses only 40U of rack space; a similarly
performing HDD RAID system would require at least five times
this rack space.
Turbo
The Turbo feature allows storage administrators to
boost performance of the RamSan-5000 even further by dedicating
the fastest part of the RamSan to the write-intensive components
of their applications. This change delivers microsecond response
times. The Turbo feature also prolongs the life of the Flash
memory used in the RamSan-5000. Turbo works by allowing
administrators to lock a LUN entirely in the RamSan-5000 high
speed RAM cache, thus dedicating a portion of the cache to a
specific dataset such as write-intensive metadata, redo logs,
temporary space, or tablespaces. The RamSan-5000�s high
availability features, such as redundant battery and
RAID-protected Flash ensure that the data in the locked LUN is
persistent, even in the event of an external power loss.
Terawatch
The RamSan-5000 is monitored by TeraWatch which allows for easy
management of multiple RamSans from a single management console.
TeraWatch monitoring software presents a summary view of all
installed RamSan modules and provides a single point to monitor
the performance and any potential problems with the RamSan
modules. Terawatch is a part of the same management software
program used to manage the RamSans individually.
The Heart of the RamSan-5000: The RamSan-500
The RamSan-500 is the basic unit from which the RamSan-5000 is
configured. The RamSan-500 is the most important advance in
solid state storage in the last twenty years. The system is
designed for high IO data warehousing, high bandwidth data
acquisition, and rich media environments. The RamSan-500 is a
hybrid of DDR RAM and Flash Memory (NAND-SLC). The judicious use
of DDR RAM cache and advanced Flash Memory architecture extends
the usability of this hybrid device into applications with large
block sequential or random writes, small block synchronous
sequential writes and any read-intensive application.
