Description
The RamSan-400 is the storage appliance
built for speed. Its data storage is based on fast DDR RAM media
instead of mechanical rotating drives. With a memory bus architecture
similar to high performance servers, the RamSan-400 has the extra
bandwidth (3 GB/sec) needed for heavy operations. Its low latency
allows support for dozens of servers immediately without any
performance degradation. Low latency has two advantages: it provides
users with 100x faster response times and allows 100x more users to
access the same volume. The RamSan-400 supports 2-8 4-Gb Fibre Channel
ports operating at full speed. The RamSan-400 provides an incredible
performance improvement over the best disks.
RamSan-400 highlights:
- 3 Gigabytes per Second
- 400,000 IOPS
- Up to 128 GB Storage
- 2-8 4-Gb FC Links
- Hot-swap Modules
Typical Storage Hierarchy
As computer performance increases
faster than rotational disk performance, the traditional, two-level
storage hierarchy scheme needs a new performance level. The
high-performance RamSan-400 fills this need by allowing users to
implement a three level storage hierarchy. Even under heavy load
conditions, the RamSan-400's I/O power and bandwidth make it possible
for all of your computers to have immediate access to highly active
data files simultaneously
Installation and Management
The RamSan-400 is as easy to install as
a disk drive. In its simplest configuration, it provides a direct link
to one server through a host bus adapter (HBA). In its expanded
configuration, it can be linked through Fibre Channel switches to
hundreds of servers or workstations via SANs. Basic management
operations, including manual shutdown and any alerts, are available
from the front panel screen. Full monitoring and configuration
capabilities are available over any browser via a protected Java
applet. The RamSan-400 is fully SNMP compatible.
Highly Reliable Storage
With any storage device, reliability is
a primary concern. The RamSan-400 is designed to offer superior
reliability to other solid state disks and RAID devices. Its standard
features include: chipkill-protected RAM, hot swap power supplies,
failover Fibre Channel ports, SNMP compatibility, three redundant
internal batteries, and four redundant, hot swappable power fail
backup disks.
Non-Volatile Backup Methods
The RAM used to give the RamSan-400
record-breaking performance would generally lose its data if power was
lost. To ensure non-volatility, the RamSan-400 includes batteries and
two distinct backup methods to its redundant internal RAID disks,
configurable per LUN, to give the user the ultimate in versatility and
reliability. |
