Serial ATA connectors are designed for hot swapping. Many server and RAID systems provide hardware support for transparent hot swapping. The designers of the SCSI standard prior to SCA-2 connectors did not target hot swapping, but in practice, most RAID implementations support hot swapping of hard disks. Serial ATA Serial ATA (SATA, abbreviated from Serial AT Attachment) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives. Serial ATA succeeded the older Parallel ATA (PATA) standard to become the predominant interface for storage devices. Serial ATA industry compatibility
Thin client farm. The server-side infrastructure uses cloud computing software such as application virtualization, hosted shared desktop (HSD) or desktop virtualization (VDI). This combination forms what is known as a cloud-based system where desktop resources are centralized at one or more data centers. The benefits of centralization are hardware resource optimization, reduced software maintenance, and improved security. Thin client hardware generally support a keyboard, mouse, monitor, jacks for sound peripherals, and open ports for USB devices (e.g., printer, flash drive, webcam). Some thin clients include legacy serial or parallel ports to support older devices such as receipt printers, scales or time clocks.
