10 Adding TL895 Tape Drives to the Compaq Enterprise Backup Solution
Overview
According to the Strategic Research, storage requirements are on their steepest ramp ever and
the result is that data protection continues to grow in importance. The Novell and Windows NT
data centers are taking on a higher level of corporate data responsibilities. The trend for
corporations to centralize their servers will continue, while storage requirements become more
critical.
The cost-effective, Compaq StorageWorks TL895 DLT Tape Library helps ensure enhanced
productivity and data protection across the enterprise. By integrating automated backup,
archiving, and Hierarchical Storage Management (HSM) for departmental and enterprise
operations, it keeps pace with other storage schemes.
Targeting the secondary storage needs, adding the TL895 to the Enterprise Backup Solution
(EBS) product mix provides three primary enhancements:
1. Increased performance The TL895 offers up to seven DLT 35/70 drives for transfer
rates above 180 GB/hr for 2:1 compressed data.
2. Increased capacityThe TL895 supports up to 7 TB of data assuming 2:1 compression.
The TL895 is based on industry leading Digital Linear Tape (DLT) technology, featuring
96 data media slots and four portal slots, allowing customers to retain more data.
3. Increased ScalabilityThe TL895 is available in two to seven drive configurations to
match performance and retention needs, allowing lights out operations.
Other TL895 benefits include:
Simpler management The TL895 simplifies management by offering high
performance, capacity, and tape retention in one integrated system. Compaq Insight
Manager provides a complete suite of tools to enhance enterprise management.
Enhanced cabling systemThe TL895 offers differential SCSI attachments for cabling
requirements up to 20 meters from the Fibre Channel Tape Controller (FCTC). Fibre
Channel cable connections are available up to 500 meters on 50 m Multimode Fiber.
CompactWith a footprint of 6 sq. ft. (1.8 sq. m), this compact form factor integrates
well with standard rack environments, utilizing a front load port and drive access door for
normal maintenance and operation.
Ease of UseThe TL895 is designed with an integrated bar-code reader for automated
media inventory and offers automatic calibration of the robotic arm with respect to drives,
slots and the I/O port. A user-friendly GUI control panel with multi-functional capabilities
makes management and troubleshooting easy.
ReliabilityThe TL895 has extremely high robotic reliability, with greater than two
million mean swaps between failure.
Increased Investment ProtectionThis new architecture ensures investment protection
by allowing upgrades from existing direct attached solutions to the EBS.
The TL895 will be used as a component of the EBS to provide a centralized data repository for
the backup data. The library will be connected to the Fibre Channel loop via Fibre Channel Tape
Controllers (FCTC) and SCSI differential cabling. The FCTCs are connected to a Compaq
Fibre Channel Hub 12 through Fibre Channel cables. Multiple Compaq servers will also be
