Superior Performance
Bursting with power to handle the most demanding storage applications,
the STORM F8 Disk Controller Module features industry-leading
capabilities:
 8
independent 2-Gb/s (200 MB/s) Fibre Channels providing 1600
MB/s bandwidth
2
high-speed microprocessors
5
high-speed internal buses
RAID
0, 1, 0+1, 3, 5, JBOD
Read-ahead,
write-through, and write-back caching configurable for each
LUN
Cache
parameters (cache size, cluster size, look ahead, write back
allocation) configurable by LUN
Pipelined
read and write operations
With its ability to define individual LUN characteristics
and their caching parameters, the STORM Disk Controller Module
provides superior performance over a wide range of applications:
from intensive high-churn small random I/O operations like
data base systems to demanding high throughput large sequential
file operations like video streaming. The STORM Disk Controller
Module can configure LUNs independently, so that STORM Disk
Storage Systems can serve as information appliances in small
dedicated configurations and as information utilities in large
network configurations.

Superior Availability
To provide continuous storage system operation, the STORM Disk Controller
Module continuously monitors its subsystems and the modules connected
to it, displays that information on the front panel and a remote
GUI, and takes corrective action to mitigate the effect of problems.
Continuous Monitoring Designed in a self-contained
1U rack mount enclosure with its own redundant hot-swappable load-sharing
power supplies, power cords, and fans, the STORM Disk Controller
Module continuously monitors its status and the status of attached
Disk Enclosure Modules.
Information Display and Notification Whenever
the STORM Disk Controller Module detects a problem, it notifies
users in several ways: the VFD display, the audible alarm, the RECON
remote GUI, and sending email to administrators.
Corrective Action In the event of a problem,
the STORM Disk Controller Module takes corrective actions to keep
the system operating while the problem is being addressed. STORM
uses global spare disks and 3 types of zoned spares (for LUNs, disk
channels, or disk enclosure modules), redundant power supplies and
fans, and redundant Fibre Channels for continuous operation.
Superior Configurability
The eight 2-Gb/s Fibre Channels of the STORM Disk Controller Module
can be configured as either host or disk channels, providing multiple
configurations to optimize performance and availability based on
application requirements.
Each
disk Fibre Channel can support 120 disks, enabling systems with
up to 840 disks providing over 120TB storage!
Each
host Fibre Channel can support switched fabric, arbitrated-loop,
or point to-point configurations to support SAN, DAS, and NAS configurations.
After installation of a STORM Disk Storage System, you can easily
augment the size of your storage with additional Disk Enclosure
Modules. The additional storage can be used for new LUNs or for
augmenting existing LUNs. The STORM Disk Controller Module also
provides LUN virtualization by restricting access to LUNs based
on the hosts? WWN.
RECON GUI
The RECON (REmote Control, Observation, and Notification System)
GUI is a platform-independent Java program that runs on the STORM?
Disk Controller Module like a web page. Connecting to your network
through a standard Ethernet port, each STORM? Disk Controller Module
has a unique Internet address so that any computer with a Java-enabled
browser can monitor status and performance and initiate system actions.
Applications
With their advanced capabilities, Digi-Data STORM Storage Systems
support a wide variety of demanding applications:
High-churn
transaction processing
Continuous
24 x 7 operation even when subsystems fail
Large
file applications requiring high throughput
Large
storage large applications, requiring multiple terabytes
STORM Storage Architecture
The STORM (STorage On Redundant Modules) Storage System Architecture
extends the fundamental precepts of RAID to provide superior performance,
availability, and configurability for demanding storage applications.
STORM Storage Systems comprise a number of independent redundant
storage modules, including:
Disk
controller modules
Disk
enclosure modules
Uninterruptible
power supply modules
Fibre
channel switches and HBAs STORM Disk Storage Systems can survive
the failure of a disk, power supply, fan, Fibre Channel connection
to host or disk, disk channel, and disk enclosure.
