A typical RAM-SAN
application is one in which speed is the ultimate requirement.
When productivity is hampered by SAN performance, the RAM-SAN
is the solution. It
provides access on demand for all attached devices without any loss of
performance, even under extreme loads.
The RAM-SAN's performance is a direct result of using
SDRAM storage with a high-bandwidth (3 GB/sec) I/O capability. This I/O bandwidth services up to 15 Fibre Channel
interfaces simultaneously while providing a low access latency for
each port, regardless of particular access
The RAM-SAN has a
storage capacity of 64 Gigabytes, an internal bandwidth of 3,000
MB/sec, and 15 Fibre Channel links.
These numbers far exceed the performance of currently available
RAID technology, as well as other competing SSDs, making the RAM-SAN
ideal for a wide range of high performance applications.
applications, 64 Gbytes is enough to store an entire database, and
only a single RAM-SAN is needed to dramatically improve application
performance. For larger
databases, multiple RAM-SANs can be arrayed as a logical volume.
Alternatively, DBAs can move database “hot files” to the
RAM-SAN. Hot files
include frequently accessed indices, logs, and tables.
Not only is hot file performance dramatically faster due to the
RAM-SAN, but RAID performance also improves because the most
frequently accessed files are stored on a separate device.
applications include multi-user relational databases, “hot file”
storage, high-traffic web page retrievals, recording or playback of
real-time data streams (e.g. HDTV), and many other
applications. Store your
OLTP database on the RAM-SAN and you will see instant and dramatic
improvements in application response time.
If your ERP system is facing storage bottlenecks, the RAM-SAN
can be used to open up the I/O floodgates.
Data warehouses with heavy user access requirements, complex
queries, or fast load requirements will see a dramatic performance
improvement with the installation of a RAM-SAN.
RAM-SAN meets the requirements of these applications, as well as many
others, with unmatched performance and flexibility.
It can be used in a variety of network configurations,
depending upon the requirements of the particular application. Used in
conjunction with a RAID, the RAM-SAN may be configured to mirror all
RAID writes while servicing all READ operations.
This allows the RAM-SAN to deliver outstanding READ
performance, while the RAID provides data persistence.
Used in a standalone configuration or for “hot file”
storage, the RAM-SAN will deliver outstanding performance for both
READs and WRITEs. Regardless
of the application, the RAM-SAN is capable of delivering the ultimate
