XLS Library System
Patent-pending COMPASS ARCHITECTURETM • Shorter Travel, Lower Power, Higher Reliability
• Very scalable drives, I/O ports, and slots
• High storage density: over 100 tapes per square foot
X-LinkTM: Single-view worldwide interface
XLS PRESENTATION Rev 034
XLS True Scalability Scaleable capacity
• Starts at 355 slots, scales to over 6,000 slots• In cabinet capacity expansion options• Balance tape drives and storage slots• Very economical 1,075 slot MEM expansion module
Scaleable performance• Two sizes of base LRM Module available
• 8 logical library partitions standard• Start at 4 drives• Scales to 96 drives• Up to 120 I/O slots • Intermix SCSI and FC drives

XLS Building Blocks
Mix and Match to Create the Right Solution
LRM (Library Resource Module) MEM (Media Expansion Module)Standalone libraryContains drives, I/O ports, storage slots, robotics, control, and powerActs as nucleus of larger systems
Rotating carousel holds 1,075 cartridgesConsumes less than 9 sq. ft. floor spaceAttaches to either side of an LRM
XLS PRESENTATION Rev 036
XLS Compass Architecture
Very high density per square foot
Low power consumption
Simple expansion!
LRM robot reaches into MEM-never leaves the LRM
Access 2,800 tapes in 21” of horizontal robot travel
System expands by alternating LRM’s and MEM’s

XLS Configurations
High storage density coupled with flexibility during growth Less linear movement to access large volumes of cartridges, over
2,800 cartridges can be accessed with an average 21” X axis motion “Low Speed” robotics motion profile is more reliable and requires
less power and cooling Cartridge access performance does not degrade when expanding
“I need to expand my XLS library
system”
“My raw storage needs are outpacing my access needs,
I will add another MEM”
“I need to add more tape drives to increase my access capability, I
will add another LRM”

Expansion Door Slots
Each door can hold 110 additional tape storage slots
The 820500 can accommodate one additional door expansion
The 832700 can accommodate two additional door expansions
The door slots block the view into the interior of the library

Robot
XYZ + rotational theta axis = Compass Architecture
Short travel means low power and increased reliability
Uses closed loop servo motors for precise positioning
Bar code reader also used as absolute position sensor during mechanical calibration
XLS PRESENTATION Rev 0317
Auxiliary Equipment Rack
Optional for either 820500 or 832700 LRM
6U “in form factor” or 8U Equipment mounts on its side Unique latching scheme
provides easy access to front and rear of equipment mounted in rack
Independent AC power provided for equipment mounted in rack
XLS PRESENTATION Rev 0318
Drive Bays
Four LTO tape drives per drive bay 820500 has one drive bay standard,
supports a maximum of five drive bays for a total of 20 tape drives
832700 has two drive bays standard, supports a maximum of eight drive bays for a total of 32 tape drives
Any mix of SCSI or Fibre channel drives
Each drive bay displaces 30 tape storage slots
XLS PRESENTATION Rev 0319
Drive Carriers XLS drive carriers slide into the
back of the drive bay
No tools are required to remove/exchange individual drives
Each drive bay location is individually controlled, drives may be brought offline independently
Blank carriers are used to block off empty drive positions, interlock prevents robot motion with empty drive bay positions

Drive Carrier Indicators
Each carrier has an individual drive status LED to easily identify the failed drive
The LED indicates if the drive is online/offline
Fibre drives have additional Link and Activity indicators
