146GB SAS disk assembly Oracle Sun 540-7868

Description

The Oracle Sun 540-7868 is an enterprise-class 146GB SAS disk assembly designed for compatible Sun server and storage platforms. It combines a high-performance 10,000 RPM SAS hard disk with the appropriate mounting bracket for installation in supported systems.

Oracle documentation identifies 540-7868 as a 146GB 10K RPM SAS disk assembly with bracket and disk, and classifies it as a Customer Replaceable Unit (CRU) with hot-service capability for supported Oracle server configurations.

The assembly is based on a 2.5-inch Small Form Factor (SFF) enterprise SAS drive. Sun System Handbook documentation lists several qualified drive variants for this assembly, including Seagate and Hitachi 146GB 10K RPM SAS drives.

The 10,000 RPM spindle speed provides responsive mechanical storage performance, making the drive particularly appropriate for operating-system volumes, boot disks, applications, databases, and other workloads where faster disk access is preferred over maximum storage capacity.

Key Specifications

Oracle’s Sun Blade 6000 Disk Module documentation also lists 540-7868-xx as a supported 146GB, 10K SAS mechanical disk with bracket.

Key Features & Benefits

• 146GB enterprise storage capacity
• 10,000 RPM rotational speed
• Enterprise SAS interface
• Compact 2.5-inch SFF form factor
• Supplied as a complete disk assembly
• Includes compatible mounting bracket
• Suitable for OS and boot-disk applications
• Designed for Oracle/Sun enterprise server environments
• Suitable for hot-plug/hot-service configurations where supported
• Ideal for replacement and server maintenance
• Useful for enterprise hardware refurbishment

OS Disk Application

The 540-7868 can be used as an operating-system disk in compatible Oracle/Sun server configurations. Its 146GB capacity provides space for the operating system, boot files, system utilities, logs, and associated application components.

The 10K RPM speed provides faster mechanical access than conventional 7.2K RPM enterprise HDDs, making it suitable for system volumes where responsive disk access is important.

Drive Variants

An important point for inventory listings is that 540-7868 identifies the Oracle/Sun disk assembly, while the actual HDD installed in the assembly may vary.

Sun documentation lists qualified drive variants including:

• Seagate ST9146802SS — 146GB, 10K RPM SAS
• Hitachi HUC101414CSS300 — 146GB, 10K RPM SAS
• Seagate ST9146803SS — 146GB, 10K RPM SAS
• Hitachi HUC103014CSS600 — 146GB, 10K RPM SAS

Oracle/Sun documentation also records the 540-7868 assembly as replacing 540-7355 in certain configurations.

Compatible Platforms

The 540-7868 has been documented across several Oracle/Sun platforms, including:

• Sun SPARC Enterprise T5120
• Sun SPARC Enterprise T5220
• Sun Storage 7110
• Sun Fire X4240
• Sun Fire X4170
• Sun Blade 6000 Disk Module
• Other compatible Oracle/Sun systems supporting the 540-7868 assembly.

Interface & Performance

The drive uses Serial Attached SCSI (SAS) technology and operates at 10,000 RPM.

Depending on the specific drive installed in the assembly, the SAS link generation may vary. For example, the Seagate ST9146803SS variant is documented as a 6Gb/s SAS drive, while other 540-7868 configurations use earlier SAS generations.

For this reason, the safest store specification is “146GB 10K RPM SAS” unless the exact drive model contained in the assembly has been verified.

Recommended Applications

• Oracle/Sun OS boot disks
• Enterprise server operating systems
• Oracle Solaris environments
• Sun SPARC server infrastructure
• Sun x86 server platforms
• Database servers
• Enterprise application servers
• Data-center storage
• Server replacement
• Storage maintenance
• Hardware refurbishment

Compatibility Note

The 540-7868 is a platform-specific Oracle/Sun disk assembly. Before installation, verify the target server/storage model, SAS compatibility, drive firmware, bracket configuration, and supported disk capacity.

If the item is being sold as an OS disk, it is also recommended to verify whether the buyer requires a specific drive manufacturer, firmware revision, or Oracle/Sun-qualified HDD model.
