Introduction to the IBM 49Y1840 300GB Hard Disk Drive

49Y1840 is a hard disk drive (HDD) manufactured by IBM. It is designed for use in server systems, where reliability and performance are critical factors. This HDD has a capacity of 300 gigabytes (GB), a rotational speed of 10,000 revolutions per minute (RPM), and uses Serial-Attached SCSI (SAS) interface technology. It also has a data transfer rate of 6 gigabytes per second (Gbps), and a small form factor of 2.5 inches, making it easy to install and hot-swappable. In this article, we will discuss in detail the technical specifications of the 49Y1840 hard drive.

Capacity and Form Factor

The 49Y1840 hard drive has a capacity of 300GB, which is sufficient for many server applications. It can store large amounts of data, including applications, databases, and files. This capacity is suitable for small to medium-sized businesses that require fast and reliable storage solutions.

The 49Y1840 hard drive also has a small form factor of 2.5 inches, which makes it compatible with most server systems. This small size allows for more drives to be installed in a single server, increasing storage capacity and performance. The 2.5-inch form factor is also useful for rack-mounted servers, which have limited space for components.

Rotational Speed

The 49Y1840 hard drive has a rotational speed of 10,000 revolutions per minute (RPM). This high speed enables faster data access and transfer rates, making it ideal for applications that require high performance. The fast rotational speed also reduces latency, which is the time taken for the hard drive to locate and retrieve data.

Serial-Attached SCSI (SAS) Interface

The 49Y1840 hard drive uses the Serial-Attached SCSI (SAS) interface technology. SAS is a point-to-point interface that connects the hard drive directly to the server's motherboard. This interface offers several advantages over other interface technologies such as SATA.

One advantage is that SAS supports higher data transfer rates. The 49Y1840 hard drive has a data transfer rate of 6 gigabytes per second (Gbps), which is faster than the maximum transfer rate of SATA III, which is 6Gbps.

Another advantage of SAS is its ability to support multiple devices connected to a single controller. This feature allows for more efficient use of resources and reduces the number of controllers required for a server system.

Hot Swap

The 49Y1840 hard drive is hot-swappable, which means it can be replaced without shutting down the server system. Hot-swapping reduces downtime and allows for maintenance to be performed without disrupting operations. The hard drive is also designed to be inserted and removed from a tray, making it easy to replace.

Reliability & Compatibility

The 49Y1840 hard drive is designed for use in server systems, where reliability is critical. It has several features that ensure data integrity and minimize the risk of data loss. One of these features is error correction code (ECC), which detects and corrects errors in data.

The hard drive also has a mean time between failures (MTBF) of 1.6 million hours. MTBF is the average time between failures of a component, and a high MTBF indicates a low failure rate. The 1.6 million hours MTBF of the 49Y1840 hard drive makes it a reliable storage solution for server systems.

The 49Y1840 hard drive is compatible with many server systems, including those manufactured by IBM. It is also compatible with other systems that support the SAS interface. This compatibility makes it easy to integrate into existing server systems, reducing the cost of upgrading storage solutions.
