The recommended disk type for a transactional database where performance is the primary concern and budget is secondary is SAS (Serial Attached SCSI).
Here is a detailed explanation of each disk type:
A) FC (Fibre Channel): Fibre Channel is a high-speed network technology used to connect storage devices to servers. Fibre Channel disks are designed for high-end applications that require high speed, high availability, and high reliability. However, they are expensive and require specialized hardware and software.
B) iSCSI (Internet Small Computer System Interface): iSCSI is a network protocol used to transport block-level storage data over TCP/IP networks. iSCSI disks are cost-effective and can provide good performance, but they may not perform as well as Fibre Channel or SAS disks.
C) SAS (Serial Attached SCSI): SAS is a point-to-point serial protocol used to connect devices to a computer's motherboard. SAS disks offer high performance, reliability, and scalability. They are more expensive than SATA disks, but less expensive than Fibre Channel disks. SAS disks are typically used in high-performance, mission-critical applications such as transactional databases.
D) SATA (Serial Advanced Technology Attachment): SATA is a point-to-point serial protocol used to connect storage devices to a computer's motherboard. SATA disks are the most common type of hard drive used in desktop and consumer-grade storage systems. They are cost-effective, but not designed for high-performance applications such as transactional databases.
In summary, while Fibre Channel may offer the highest performance, its cost may be prohibitive. iSCSI is cost-effective, but may not offer the performance needed for a transactional database. SATA is not suitable for high-performance applications. SAS, with its balance of performance, reliability, and cost, is the best choice for a transactional database where performance is the primary concern and budget is secondary.
