The DVSA Premium series, Bosch Digital Video Storage
Array, is built for the security industries most demanding
digital video storage applications, providing high capacity,
unlimited flexibility and unmatched reliability.
Functions
Bosch DVSA satisfies the ever increasing demands of
CCTV for video – high speed recording, high performance
playback, uninterruptable reliability and massive
capacities. With complete RAID 5 protection and SATA-II
hard drives, it is ideally suited for when the highest level
of data availability is demanded.
The “Premium” models are fully featured RAID 5 disk
arrays. With the focus on non stop reliabillity all critical
components, including the drive trays, power supply units
and cooling modules, are hot-swappable within the
cableless modular chassis.
Bosch DVSA “Premium”models are also designed for
expansion. Two Gigabit Ethernet ports allow the
connection of up to 31 Bosch video servers over standard
Ethernet networks, which improves the cost-effectiveness
of the RAID-based solution. The Bosch DVSA iSCSI
solution is ideal for building a shared pool of storage for
Bosch Video Servers.
In the event of a failure, the Bosch Digital Video Storage
Array sounds an audible alarm to notify a user. The units
also ensure that system managers can be constantly
updated with their status via a choice of channels,
including email, fax, LAN broadcast,
SNMP traps, MSN Messenger and SMS messages
depending on the infrastructure in place and user
preferences.
The 4 or 12 SATA-II drive channels are routed through the
backplane board to the lockable drive trays installed via
the front of the Bosch DVSA. The completely cableless,
backplane-based design eliminates problems associated
with cable connections and offers a higher level of
serviceability.
Bosch DVSA supports multiple RAID configurations, each
with distinct write policy, stripe size and optimization
modes. Hot rebuild and numerous fault correction
mechanisms ensure the highest standard of RAID
protection. Each unit has a battery backup unit (BBU)
installed to prevent data loss during a power failure.
When used with the Bosch iSCSI-based applications, e.g.
VRM, the DVSA Premium Series iSCSI Digital Video
Storage Array provides a bandwidth up to 200 Mbit/s and
43 concurrent iSCSI sessions.
Combined with comprehensive firmware features, the
Bosch Digital Video Storage Arrays ensures extreme
reliability and exceptional data availability in today’s most
data intensive video storage environments. A highly
reliable storage solution is assured by factory burn-in
procedures and extensive selection process for hard disk
drives, covered by the Bosch 3 year warranty program.
Note for ordering:
