Q2. Which four are recommendations for optimizing library performance for an SL8500?
A. Install redundant robotics.
B. Enter sufficient scratch cartridges to each rail.
C. Use ExLM with ACSLS.
D. Install tape drives that use the same media types on the same rails.
E. Use the float option.
Answer: A,B,D,E
Explanation: A: Redundant Robotics
A single SL8500 rail section can accommodate two robots, for a total of eight robots per library.
These robots can operate in parallel, significantly increasing the overall performance of the library.
B: When populating the rails:
Scratch cartridge pools: make sure the rails have enough scratch cartridges
D: When populating the rails:
Media types: make sure the rails have compatible cartridges for the tape drives
Note: Ways tape drives can enhance performance of the library are by:
.Placing tape drives in the outer tape drive columns to minimize dual robotic contention.
.Grouping tape drives by type on the same LSM.
.Keeping compatible media and drives on the same LSM.
.Allocating LSMs to support specific application workloads.
.Maintaining free cells on each LSM to support dismounts using the float option.
E: Cartridge Float Both ACSLS and HSC have cartridge float enabled by default. *Cartridge float is a feature that allows ACSLS or HSC to place a dismounted tape cartridge in an empty slot in the same LSM as or a closer LSM to the tape drive if the tape originally came from a different LSM using a pass-thru operation. *This feature minimizes elevator and pass-thru port activity by not requiring the cartridge to be returned to its original slot in another rail or library. Warning – Turning the default Float option OFF can have serious consequences for overall library performance. In both ACSLS and HSC, turning Float OFF can greatly increase the total robotics activity to unacceptable levels.
Q3. Which two features are available through the Sun Storage Archive Manager?
A. encryption of data to tape to safeguard against the misuse of sensitive data
B. Recovery of volumes that are not found in their expected locations in the StorageTek tape
C. Archiving of data using an open format
D. Continuous archiving of file data to as many as four local and remote storage locations
Answer: C,D
Explanation: C: With Sun Storage Archive Manager software, data is archived using an open format to ease future access and avoid vendor lock-in.
D: . Sun Storage Archive Manager software continuously archives file data to as many as four local and remote storage locations for effective and efficient data protection and recovery

Q4. Which two items describe the StorageTek library Console software?
A. It is a remote operator panel to the tape library provided through a graphical user Interface (GUI)
B. It allows for a centralized point of control for multiple libraries and back-up applications and efficiently shares library resources with any application on any system.
C. It runs on a PC and connects to the library via Ethernet connection (TCP/IP).
D. It allows you to consolidate multiple application dedicated libraries into one centralized library or a string of libraries accessed via a single point of control.
Answer: A,B
Explanation:
Note: The StorageTek Library Console (SL Console) is a Java-based software application that provides a graphical user interface (GUI) for monitoring and managing the StorageTek library. Following are some of the activities you can perform with the SL Console:
* Manage and configure library partitions (optional feature)
* View and modify status and properties of the library and associated devices (drives, CAP, robots, and elevators)
* Perform an audit on all or part of the library
* Perform a self-test on the library or an associated device
* Perform a diagnostic move (exercise a robot)
* Locate a cartridge
* Move a cartridge from one location to another
* Display library logs
* Display error explanations
* Download new library firmware while the library is in operation
* Display context-sensitive help

Q5. The major consideration of the content management plan for an SL8500 is:
A. to allocate ACSLS and HSC host software cartridges and drives to rails to support each application
B. to allocate tape application workloads to rails of similar cartridges and drives typo to support each workload
C. to allocate tape application workloads to evenly spread cartridge and drivecapacity across each rail to support each workload
D. to evenly spread cartridge and drive capacity across all rails
Answer: C
Explanation: Note: Recommendations include:
* Placing applications that require significant enters and ejects on rails adjacent to CAP magazines.
* Assigning workloads to separate rails
* Combining rails for a workload

Q6. If you have a customer with throughput requirements >10 TB/hr, which libraries would you recommending?
A. SL24 or SL48
B. SL48 or SL500
C. SL500 or SL3000
D. SL3000 or SL8500
Answer: D
Explanation: SL3000 Maximum Native Throughput (TB/hr):48.4 SL8500 Maximum Native Throughput (TB/hr):552.9

Q7. What ACSLS utility would be used to start both ACSLS and the database?
A. db_comman d startB.
bdb.acsss
C. rc.acsss
D. restart.acsss
Answer: C
Explanation: The rc.acsss utility brings ACSLS up and automatically starts the database. There is no need to manually start the database.

Q8. Which three scenarios would be more optimal for logical partitioning than physical partitioning?
A. Customer would like to partition an SL8500 complex into smaller partitions.
B. Customer would like to partition an SL8500 or an SL3000 into more partitions than physical partitioning allows.
C. Customer would like to partition an SL3000 into two partitions, one for mainframe and one for open systems.
D. Customer would prefer multiple partitions to be controlled by VOLSER than physical address.
Answer: C
Explanation:
Q9. When configuring drives in logical libraries which of the following is false?
A. To assign multiple drives to a logical library, the drives must be located in the same ACS.
B. Drives may be shared across multiple logical libraries.
C. Both LTO and Enterprise drives may be configured into logical libraries.
D. Drives may only be added to logical libraries through the ACSLS GUI.
Answer: A
Explanation:
Note:When partitioning the StorageTek SL8500, SL3000 or SL500 libraries into logical libraries, one can assign volumes and drives to the logical library to enable library consolidation, gain capacity on demand, and allow only the client connected to the logical library to access those volumes and drives.
Note: logical library
A virtual representation of a physical library. Synonymous with virtual library partition.
