Description
Product overview
The IBM 95P4949 is a type of data storage device known as a tape drive. It is designed to read and write data onto magnetic tape cartridges. The specific model, 95P4949, is an internal tape drive designed for use with IBM’s LTO Ultrium-4 format tapes. In this article, we will explore the features and specifications of the IBM 95P4949 tape drive.
A tape drive is a device used for reading and writing data onto magnetic tape cartridges. It works by moving the tape past a read/write head that magnetically records or reads the data onto the tape. Tape drives have been used for decades as a reliable form of data storage, and they continue to be used today in many industries.
The IBM 800/1600GB LTO Ultrium-4 SAS FH Internal Tape Drive
The IBM 95P4949 is an internal tape drive designed to be installed inside a server or computer system. It uses the LTO Ultrium-4 format, which is a high-capacity magnetic tape format designed for backup and archival storage. The tape drive is capable of storing up to 800GB of uncompressed data, or up to 1600GB of compressed data on a single tape cartridge.
SAS Interface
The IBM 95P4949 tape drive uses a SAS (Serial Attached SCSI) interface to connect to a computer system. SAS is a high-speed, point-to-point interface used for connecting storage devices to a computer system. It is commonly used in enterprise-level storage systems due to its speed and reliability.
Full Height Form Factor
The IBM 95P4949 tape drive has a full height form factor, meaning that it takes up the full height of a standard computer system’s drive bay. This is in contrast to half-height form factor drives, which are smaller and take up less space in a system. Full height drives are generally considered to be more robust and reliable, but they may not be suitable for systems with limited space.
Performance
The IBM 95P4949 tape drive has a maximum data transfer rate of 120MB/s, assuming the data is compressed. If the data is uncompressed, the transfer rate drops to 80MB/s. These transfer rates are relatively slow compared to modern solid-state storage devices, but they are still considered to be fast for tape drives. The slower transfer rates are offset by the large capacity of the tape cartridges, making tape drives ideal for archival storage or backup applications.
Compatibility
The IBM 95P4949 tape drive is designed to be compatible with a wide range of operating systems, including Windows, Linux, and various UNIX variants. It is also compatible with a range of backup software packages, including IBM’s own Tivoli Storage Manager. This wide range of compatibility makes the tape drive a versatile option for organizations that need to store and backup data across multiple platforms.
Reliability
Tape drives are known for their reliability, and the IBM 95P4949 is no exception. The LTO Ultrium-4 format is designed to be highly reliable, with a claimed average media life of 30 years. The tape drive itself is also designed to be highly reliable, with a mean time between failures (MTBF) of 250,000 hours. This means that the drive should be able to run continuously for over 28 years before experiencing a failure.
Overall, the IBM 95P4949 is a reliable, high-capacity tape drive designed for use in enterprise-level backup and archival storage applications. Its SAS interface, full-height form factor, and wide range of compatibility make it a versatile option for organizations that need to store and backup data across multiple platforms. While its transfer rates may be slow compared to modern solid-state storage devices,
