HP StorageWorks EML E-Series Tape Libraries

HP StorageWorks EML E-Series Tape LibraryThe HP StorageWorks Enterprise Modular Library (EML) E-Series Tape Libraries provide reliability, scalability and manageability with robust data protection and investment protection in heterogeneous Storage Area Network (SAN) environments. The EML delivers superior data availability with protection against SAN event disruptions using the built in HP StorageWorks Extended Tape Library Architecture (ETLA). ETLA intercepts rogue I/O requests from applications or new servers and prevents those requests from interrupting backup or recovery processes. You can also flexibly scale to 808 TB compressed (2:1) storage capacity or 13.8 TB/hr compressed (2:1) throughput performance from rack-ready or factory racked configurations. Easily manage the EML remotely while simplifying complex environments with logical library partitioning. The EML is ideally suited for medium to large data centers and as a companion for the HP StorageWorks Enterprise Virtual Array (EVA) family.

The EML Tape Libraries are fully integrated into the HP StorageWorks portfolio through interoperability and compatible capacity points. The EML tape library is extensively tested in the HP StorageWorks Enterprise Backup Solutions (EBS) to ensure that it works in the most rigorous environment. Documentation is provided to enable you to configure, design and implement the best data protection solution for your environment. Entry configurations start at 71 slots. Maximize capacity with 505 slots or maximize performance with 16 LTO-4 Ultrium 1840 or LTO-3 Ultrium 960 FC tape drives and 442 slots. The LTO-4 Ultrium 1840 tape drive provides encryption support. The EML delivers value through high reliability data protection, agility through modular scalability and simplicity through ease of management.
 
Centralized encryption key management solution through Secure Key Manage (SKM).
Integration of the HP StorageWorks LTO-4 Ultrium 1840 tape drive.
LTO-4 Ultrium 1840 tape drive hardware encryption for secure, high-performance backups.
Features
Secure Key Manager Support: Secure Key Manager reduces your risk of a costly data breach and reputation damage while improving regulatory compliance with a secure centralized encryption key management solution for HP LTO-4 enterprise tape libraries (EML & ESL). In addition, the SKM provides strong auditable security and reliable lifetime key archival.
LTO-4 Ultrium 1840 tape drive support: Compared to LTO-3 Ultrium 960 tape drives, LTO-4 Ultrium 1840 tape drive capacity is doubled, performance is increased by approximately 50% and encryption is supported.
AES 256-bit embedded hardware encryption with compression: Provides a high level of encryption security, with compression, for strong backup data privacy to secure confidential information and address compliance quickly.
Value - Superior SAN data availability: The EML delivers superior data availability with protection against SAN event disruptions using the HP Extended Tape Library Architecture (ETLA). ETLA intercepts rogue I/O requests from applications or new servers and prevents those requests from interrupting backup or recovery processes.
Heterogeneous SAN interoperability: The EML ensures heterogeneous SAN interoperability and solution support. Certified through the HP StorageWorks Enterprise Backup Solution (EBS), the EML is compatible with leading backup software packages, operating systems, servers, and disk arrays.
Expansion to 808 TB compressed storage capacity: The EML delivers flexible modular scalability from 71 to 505 slots for consolidating environments needing as much as 808 TB compressed (2:1) storage capacity. The number of drives and slots may be increased by the purchase of expansion modules bringing the library to 8 drives and 505 slots for maximum capacity.
Scale performance up to 13.8 TB/hr compressed (2:1) throughput: The EML has the ability to grow compressed (2:1) throughput performance up to 13.8 TB/hr. The number of drives and slots may be increased by the purchase of expansion modules bringing the library to 16 drives and 442 slots for maximum performance.
Flexible racking alternatives: The EML provides flexible racking alternatives. Choose between rack-ready configurations that can be installed at the customer site or HP factory-racked configurations that minimize installation time.
Simplicity - Remote management: The EML provides easy to use remote management, diagnostics and configuration capabilities. Utilizing HP StorageWorks Command View for Tape Libraries Software for EML or the command line interface, you can access the EML from across the room or across the globe.
Library partitioning: Simplify managing complex environments with library partitioning. HP StorageWorks Secure Manager Tape Library Software for EML allows the user to logically divide the library into smaller libraries. This function is especially useful when multiple SANs or backup software packages are present.

Product Highlights

Scalability (Investment Protection) The HP StorageWorks Enterprise Modular Library provides investment protection as your environment grows and changes. With superb scalability, the EML can flexibly scale to 808 TB compressed (2:1) storage capacity or 13.8 TB/hr compressed (2:1) throughput performance from rack-ready or factory racked configurations. Additionally, certification under the Enterprise Backup Solutions (EBS) is a continuing process. As servers and HBAs continue to change, backup software packages evolve and improve, the EML E-Series tape library will expand its compatibility.

Manageability HP StorageWorks Extended Tape Library Architecture will save library and SAN administrators time and money by simplifying library setup, configuration, and troubleshooting, increasing reliability and robustness of libraries in the SAN, integrating with leading enterprise management applications, and offering advanced features -- such as Access Control (EML Secure Manager) -- that further increases backup performance and reliability. HP offers a balanced solution - neither piece-meal nor monolithic - that includes a generous initial feature set and allows users to buy only the advanced options they need.

Reliability As data becomes more and more mission critical, and downtime becomes more costly to the enterprise, customers are requiring high availability consolidated storage solutions which offer hot-plug components and redundancies of key operating subsystems (cooling fans and power supplies). With optional redundant power distribution and power supplies the HP StorageWorks EML Tape Libraries offer the best in high availability for continuous operation. The EML provides superior data availability with protection against SAN event disruptions (HP StorageWorks Extended Tape Library Architecture). Also, this library ensures heterogeneous SAN interoperability and solution support (Certified as an HP Enterprise Backup Solutions (EBS) and uses highly dependable HP Ultrium LTO tape drives designed for 24x7 operations.

Data Privacy To greatly enhance data privacy, HP StorageWorks EML Tape Libraries are now available with LTO-4 Ultrium 1840 hardware encrypting tape drives for secure high performance backups meeting consortium specifications for LTO-4. HP Data Protector Software can enable the drive encryption and provide basic key management capabilities. Additional information regarding ISV's supporting hardware encryption is available on the HP StorageWorks Enterprise Backup Solutions (EBS) website at www.hp.com/go/ebs. The encryption on LTO-4 media occurs with or without compression, and without speed or capacity penalties. You can read LTO-2 and LTO-3 tapes, and write LTO-3 tapes, but hardware encryption is not supported in these formats.

LTO-4 uses the Advanced Encryption Standard (AES) with the longest and most secure keys -- 256 bits. AES-256 is implemented within Galois Counter Mode (GCM). This is a method of increasing AES security by efficiently adding Message Authentication Codes to ensure the integrity of the backup data stored on tape. The HP LTO-4 Ultrium 1840 Tape Drive is designed to be compliant with the emerging standard for tape drive security (IEEE 1619.1).

SKM: The HP StorageWorks Secure Key Manager reduces your risk of a costly data breach and reputation damage while improving regulatory compliance with a secure centralized encryption key management solution for HP LTO-4 enterprise tape libraries (EML & ESL). In addition, the SKM provides strong auditable security and reliable lifetime key archival. The SKM and LTO-4 drive encryption in the EML library provides a complete and secure privacy solution to protect customers' confidential data.


Density HP StorageWorks EML E-Series Libraries exceptional density and integrate seamlessly into rack-grid data centers.

HP LTO Ultrium Technology HP StorageWorks LTO (Linear Tape Open) Ultrium Tape Drives use best of breed technology. By taking the best features from other tape technologies and combining them into a single new technology, Ultrium tape drives are in a league of their own. Inclusion of innovative features such as Adaptive Tape Speed (ATS) ensure that Ultrium drives can meet the performance and reliability demands of a library environment. LTO technology is an open industry standard format; thus data written on HP StorageWorks Ultrium Tape Drives can be interchanged directly with Ultrium Tape Drives from other vendors.

Data Rate Matching Data Rate Matching combines sophisticated buffer management with HP's exclusive Infinitely Variable Adaptive Tape Speed technology, to allow the tape drive to match its transfer rate to the host speed dynamically and continuously across the whole range of transfer rates. This feature ensures that the tape drive continues to stream data regardless of the environment, and brings two big advantages:
 
  • It optimizes backup performance, regardless of the speed of the host or the network.
  • It minimizes rewinding and repositioning of the tape, reducing wear and increasing reliability.

Mixed Media Extending the E-Series flexibility and investment protection, the HP StorageWorks EML E-Series tape libraries support mixing drive technology. Technologies included are LTO-4 Ultrium 1840 FC, LTO-3 Ultrium 960 FC, and LTO-2 Ultrium 460. One drive type can be specified for CTO and the other drive types must be field installed.

HP Ultrium Storage Media HP recommends that you use HP-branded cartridges in the HP EML E-Series Tape Libraries to assure the highest level of protection for your valuable data. The test program for HP media is the most thorough and comprehensive in the industry.

All HP cartridges must satisfy an exhaustive battery of additional tests that relate directly to real life situations, where real data and real businesses are at stake. The benefit of the HP brand specification for media is consistent quality. Through the testing of thousands of HP drives and HP cartridges, the ideal formulation for backup performance is defined and then continuously monitored. This hugely resource-intensive process is unique to HP and affords deep insight into the HP+HP backup solution for a wide range of environments and duty cycles. Your best choice for ease of support and maximum dependability is to use HP-branded Ultrium cartridges at all times.

HP strongly encourages the use of bar code labels on tapes to track media and ensure optimum library performance and usability. Correctly labeling your media will allow the library to quickly determine media and drive compatibility.


Removable Magazines The EML tape library comes standard with removable magazines in every load port. The magazines allow easy loading and unloading of media and are ideal for storage.
Additional magazines are available for purchase (AD579A - 2 5-slot magazines)

LTO-4 Ultrium 1840 FC Interface Controller With LTO-4 Ultrium 1840 drives, HP delivers dual-port, native fibre SAN connectivity, while HP's Extended Tape Library Architecture (ETLA) continues to provide Secure Manager and partitioning features. One e2400-FC 2Gb interface controller is still needed and recommended for the robot. A e2400-FC 4Gb Interface Controller can be requested but is not needed for performance.

LTO-3 Ultrium 960 FC Interface Controllers As a key component of the Extended Tape Library Architecture, the Interface Controllers are integrated into the entire tape library solution. Similar to disk array controllers, the Interface Controllers provide the highest level of security, reliability, and broad interoperability for tape drives being connected into a storage area network. The EML tape libraries utilize the e2400-FC 2Gb and e2400-FC 4Gb Interface Controllers with Ultrium fibre channel tape drives. Each controller manages up to four tape drives and provides 2Gbit and 4Gbit FC connections to the SAN. (In effect, two drives per switch port) While you can mix controller types in the same library, only one controller type (e2400-FC 4Gb or e2400-FC 2Gb) may be ordered with factory integration. The other controller type must be field-installed.

HP EML LTO-4 Ultrium 1840 Internal Network Kit The purpose of the EML Internal Network Kit is to provide a private management network inside the library to connect the Interface Manager (IM) to the LTO-4 drives.
