Small Form Factor (other)
Small form factor (often abbreviated "SFF") is a term for computer components designed to a smaller than usual form factor. The term is commonly used for: * Small form factor (desktop and motherboard), desktop computers and motherboards with smaller than ATX form factor, including micro ATX ("μATX"), and micro/nano/pico ITX * NVMe, storage device connectors such as SFF-8639 (also known as U.2) and SFF-TA-1001 (also known as U.3) * Serial Attached SCSI (SAS), storage device connectors such as SFF-8482, SFF-8484, SFF-8087, SFF-8643, SFF-8470, SFF-8088, and SFF-8644 * Networking connectors especially optical fiber connectors, that may be described as small form factor compared to older form factors See also * Form factor (other) * Small Form Factor Committee * Small Form Factor Special Interest Group The Small Form Factor Special Interest Group (SFF-SIG, pronounced ''ess-eff-eff-sig'') is an international non-profit standards body focused on modular computer hardware t ...

Form Factor (design)
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard. It may also define an entire system, as in a computer form factor. Evolution and standardization As electronic hardware has become smaller following Moore's law and related patterns, ever-smaller form factors have become feasible. Specific technological advances, such as PCI Express, have had a significant design impact, though form factors have historically been slower to evolve than individual components. Standardization of form factors is vital for compatibility of hardware from different manufacturers. Trade-offs Smaller form factors may offer more efficient use of limited space, greater flexibility in the placement of components within a larger assembly, reduced use of material, and greater ease of tran ...

Small Form Factor (desktop And Motherboard)
Small form factor (SFF or SFX) is a term used for desktop computers, and their enclosures and motherboards, to indicate that they are designed in accordance with one of several standardized computer form factors intended to minimize the volume and footprint of a desktop computer compared to the standard ATX form factor. For comparison purposes, the size of an SFF case is usually measured in litres. SFFs are available in a variety of sizes and shapes, including shoeboxes, cubes, and book-sized PCs. Their smaller and often lighter construction has made them popular as home theater PCs and as gaming computers for attending LAN parties. Manufacturers also emphasize the aesthetic and ergonomic design of SFFs since users are more likely to place them on top of a desk or carry them around. Advancements in component technology together with reductions in size means a powerful computer is no longer restricted to the huge towers of old. Small form factors do not include computing devices ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NVMe
NVM Express (NVMe) or Non-Volatile Memory Host Controller Interface Specification (NVMHCIS) is an open, logical-device interface specification for accessing a computer's non-volatile storage media usually attached via PCI Express (PCIe) bus. The initialism ''NVM'' stands for ''non-volatile memory'', which is often NAND flash memory that comes in several physical form factors, including solid-state drives (SSDs), PCIe add-in cards, and M.2 cards, the successor to mSATA cards. NVM Express, as a logical-device interface, has been designed to capitalize on the low latency and internal parallelism of solid-state storage devices. Architecturally, the logic for NVMe is physically stored within and executed by the NVMe controller chip that is physically co-located with the storage media, usually an SSD. Version changes for NVMe, e.g., 1.3 to 1.4, are incorporated within the storage media, and do not affect PCIe-compatible components such as motherboards and CPUs. By its design, NVM Exp ...

Optical Fiber Connector
An optical fiber connector joins optical fibers, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all, about 100 different types of fiber optic connectors have been introduced to the market. Application Optical fiber connectors are used to join optical fibers where a connect/disconnect capability is required. Due to the polishing and tuning procedures that may be incorporated into optical connector manufacturing, connectors are often assembled onto optical fiber in a supplier's manufacturing facility. However, the assembly and polishing operations involved can be performed in the field, for example, to terminate long runs at a patch panel. Optical fiber connectors are used in telephone exchanges, for customer premises wiring, and in outside plant applications to connect equipment and f ...

Small Form Factor Committee
The Small Form Factor Committee (SFF) is an ''ad hoc'' electronics industry group formed to quickly develop interoperability specifications (as a complement to the traditional standards process). The SFF Committee was formed in 1990 to define the emerging disk drive form factor for laptop computers. In November 1992, the members broadened the objectives to complement the formal standards process in any area of the storage industry which needed prompt attention. SFF projects are in areas not addressed by standards committees because of timing, charter, or other considerations. The committee consists of members that represent companies that develop, manufacture, and sell products and components for the storage industry. Its members include but are not limited to representatives from companies such as Amphenol Interconnect, Avago Technologies, Broadcom, Dell, FCI Electronics, Foxconn, Fujitsu Components America, Hewlett Packard, Hitachi, IBM, Intel, LSI Corporation, Molex, Pan ...
