Features
The HPE StoreEver MSL2024, MSL4048, MSL8048, and MSL8096 Tape Libraries provide compact, high-
capacity, low-cost solutions for simple, unattended data backup. This unique design houses up to 12 tape
cartridges for each U of height. Tape cartridges can be accessed through removable magazines and one or
more mailslots. Each magazine holds up to 12 tape cartridges.
The libraries are compatible with most operating systems. However, the libraries require either direct support
from the operating system or a compatible backup application to take full advantage of their many features. To
verify compatibility, see the BURA Data Agile Compatibility Matrix at http://www.hpe.com/storage/
DAPRcompatibility.
The libraries are customer expandable with exchangeable tape drives. The libraries support Ultrium full-height
and half-height tape drives. To see the tape drives currently available for each tape library, see the MSL
QuickSpecs at http://www.hpe.com/storage/msl. For a list of all supported configurations, see the Business
class libraries drive matrix on the BURA Data Agile website at http://www.hpe.com/storage/
DAPRcompatibility.
The library provides two user interfaces:
• Remote management interface (RMI)—With the RMI you can monitor and operate the library from a
webpage. You can access most library functions from the RMI. See The remote management interface
(RMI) on page 57.
• Operator control panel (OCP)—With the OCP you can monitor and operate the library from the front panel.
◦ MSL2024: See Using the MSL2024 OCP on page 94.
◦ MSL4048, MSL8048 and MSL8096: See Using the MSL4048, MSL8048, and MSL8096 OCP on page

Redundant power supply
The MSL4048, MSL8048, and MSL8096 tape libraries have a redundant power supply option. The redundant
power supply allows the library to continue operating when one power supply fails. With the redundant power
supply system, the library can monitor the status of each power supply and power supply fan. The redundant
power supply can be installed without powering off the library.
For instructions on installing the redundant power supply, see Installing a redundant power supply.
HPE StoreEver 1/8 G2 Tape Autoloader and MSL Tape Libraries Encryption Kit
The encryption kit provides secure generation and storage of encryption keys. The encryption kit can be used
with any StoreEver 1/8 G2 Tape Autoloader or MSL2024, MSL3040, MSL4048, MSL6480, MSL8048, and
MSL8096 Tape Library with at least one LTO-4 or later generation tape drive. The encryption kit cannot be
used with the MSL6000.
The encryption kit supports your manual security policies and procedures by providing secure storage for
encryption keys. Access to the key server tokens and their backup files is protected with user-specified
passwords. You will need to create processes to protect the tokens and secure the passwords.
Before enabling the encryption kit, verify that the library is running the most current firmware to ensure
compatibility between the token and library.
To use the encryption kit, insert a key server token in the USB port on the back of the library and then enable
the encryption kit and configure the token from the RMI.
IMPORTANT:
When encryption is enabled with the encryption kit, the library will not use encryption keys from other
sources, such as a key management system or application software. Disable encryption in applications
writing to the library when encryption is enabled with the encryption kit. Applications that attempt to
control encryption while encryption is enabled with the encryption kit will not be able to do so, which can
cause backups or other write operations to fail.
For information about configuring and using the encryption kit, see the encryption kit user guide, which is
available from the Hewlett Packard Enterprise Information Library at http://www.hpe.com/info/storage/
docs.
Command View TL TapeAssure
HPE Command View TL software provides a browser-based GUI for remote management and monitoring of
most Hewlett Packard Enterprise libraries. With Command View TL, you can view and analyze the
performance and health of supported tape drives and media in multiple devices at the same time. In addition,
TapeAssure displays more extensive drive and media health information than is visible in the RMI.
Command View TL software is installed on a management station. The management station can also be used
to manage HPE EML and ESL Tape Libraries. For best performance, locate the management station in the
same physical location and on the same IP subnet as the library. Command View TL software is available for
download without charge from the Hewlett Packard Enterprise website at http://www.hpe.com/storage/
cvtldownload.
For information on installing and using Command View TL, see the HPE Interface Manager and Command
View TL User Guide, available from the information library: http://www.hpe.com/info/storage/docs
Command View TL support is included in all library firmware that supports LTO-5 and later generation tape
drives. To find and download the most up-to-date firmware revision, visit the Hewlett Packard Enterprise
support website at http://www.hpe.com/support/hpesc.

LTFS Support
The HPE StoreOpen Automation application simplifies use of the Linear Tape File System (LTFS)
functionality. LTFS makes tape self-describing, file-based, and easy-to-use. The automation application
extends LTFS functionality, presenting an autoloader or library and its tape cartridges as a collection of
folders. This extension results in easy data access and management. For more information about LTFS
capabilities, see http://www.hpe.com/storage/StoreOpen.
MSL8048 upgrade license
The MSL8048 can be upgraded to the capacity of an MSL8096 with TA739A, the HPE MSL8048 48 to 96 slot
license. The license enables 48 additional storage slots, including 12 slots that can be configured as
additional mailslots. To purchase the upgrade license, contact your Hewlett Packard Enterprise sales
representative or visit the Hewlett Packard Enterprise website at http://www.hpe.com.
Use the RMI Configure > License Key screen to manage the license key.
Figure 8: RMI Configure > License Key screen
After you order the upgrade license, you can access the additional slots immediately by generating a
temporary license key. The temporary key can only be enabled once and is valid for 30 days.
NOTE:
The temporary key is intended to provide instant access to the upgrade capabilities until you receive the
permanent key. The temporary key expires after 30 days. If you do not have a permanent license key before
the temporary key expires, you will lose access to the additional storage slots when the temporary license key
expires.
When you receive the permanent license key from Hewlett Packard Enterprise, enter the key and press
Submit. The permanent license takes effect when the library is rebooted. You might need to reboot the library
to enable the additional slots.
HPE MSL Library Extender
The library extender combines two libraries to create a single extended library. Before installing the extender,
the libraries must be installed in the rack rails supplied with the libraries in adjacent rack locations, one library
above the other.
18 LTFS Support

Figure 9: Library Extender installed with two MSL4048 tape libraries
The extender occupies the lower half-height drive bay of the upper library and the top half-height drive bay of
the lower library.
The upper library controls the extended library and is called the master library. The extended library uses only
the master library OCP, USB port, and Ethernet connection.
The master library controls the lower library. The lower library OCP, USB port, and Ethernet connection are
not used by the extended library.
Table 1: Library extender supported configurations
Master library Lower library Total slots Total half-height drive

MSL4048 MSL2024 72 3+1 1+0
MSL4048 MSL4048 96 3+3 1+1
MSL8096 MSL2024 120 3+1 3+0
MSL8096 MSL4048 144 3+3 3+1
If you are using the encryption kit with both libraries and then install the extender, you will need to combine
the encryption keys onto a single key server token. The extended library only uses the USB port and key
server token in the master library; the USB port in the lower library is inactive. For instructions on combining
the keys onto a single token, see the encryption kit user guide. If the number of keys on the two tokens is
greater than 100, use the Number of Keys to Backup option to generate a backup file with a subset of the
keys from one of the tokens to restore to the other token.
NOTE:
Libraries that require a license to enable all slots must have all slots licensed to operate with the Library
Extender.
Features 19

Hardware-based encryption
The LTO-4 and later generation tape drives include hardware capable of encrypting data while writing data,
and decrypting data when reading. Hardware encryption can be used with or without compression while
maintaining the full speed and capacity of the tape drive and media.
Encryption is the process of changing data into a form that cannot be read until it is deciphered with the key
used to encrypt the data. Encryption protects the data from unauthorized access and use. LTO tape drives
use the 256-bit version of the industry-standard AES encrypting algorithm to protect your data.
To use this feature, you need:
• The 1/8 G2 & MSL Encryption Kit or a KMIP-based key server or a backup application that supports
hardware encryption.
• LTO-4 or later generation media; no encryption will be performed when writing LTO-3 and earlier
generations of tape.
Your company policy will determine when to use encryption. For example, your company could require
encryption of company confidential and financial data, but not for personal data. Company policy will also
define how to generate and manage encryption keys. Backup applications that support encryption will
generate a key for you or allow you to enter a key manually.
For information about using the encryption kit, see HPE StoreEver 1/8 G2 Tape Autoloader and MSL Tape
Libraries Encryption Kit on page 17.
KMIP-based key servers
The library supports integration with encryption key management servers using the Key Management
Interoperability Protocol (KMIP) standard. KMIP is an industry standard protocol for communications between
a key management server and an encryption system. The KMIP technical committee of the OASIS standards
body (Organization for the Advancement of Structured Information Standards) developed the KMIP
specification.
The KMIP feature allows the library to obtain encryption keys from selected KMIP-compliant key managers.
These keys can be used to encrypt data as it is written to tape. Up to six key servers can be configured for
failover purposes.
For instructions on configuring the KMIP feature, see the HPE StoreEver MSL Tape Libraries Encryption Key
Server Configuration Guide, available from the Enterprise Information Library at http://www.hpe.com/info/
storage/docs.
Key managers
To use the KMIP feature, the library must have access to a KMIP key manager. Hewlett Packard Enterprise
only supports KMIP when used with a supported key manager, listed in the compatibility matrix at http://
www.hpe.com/storage/DAPRcompatibility.
Operation
When the KMIP feature is enabled and properly configured, tape data will automatically be encrypted with
keys delivered from the KMIP key manager. Tapes are encrypted on a key-per-tape basis.
Write, and append operations: The tape drive will request a key when data is written. The library, acting as
an intermediary, can request the key manager to create a key. The library then obtains that key and delivers it
to the tape drive. A name, which is associated with the media identifier, identifies the key. The key is not
retained in the tape drive any longer than necessary to perform encryption operations.
Read operations: The tape drive will request a key. The library, acting as an intermediary, obtains the key
identifier, requests that key from the key manager, and delivers it to the tape drive. The key is not retained in
the tape drive any longer than necessary to perform decryption operations.
