Enterprise And Data Center Standard Form Factor
The Enterprise and Data Center Standard Form Factor or EDSFF and previously known as the Enterprise and Data Center SSD Form Factor is a family of SSD form factors for use in data centers that is being developed by the Small Form Factor Technology Affiliate technical work group, which is itself under the organizational stewardship of the Storage Networking Industry Association. As a family of form factors, it defines specifications for the mechanical dimensions and electrical interfaces devices should have, to ensure compatibility between disparate hardware manufacturers. The standard is meant to replace the M.2 and U.2 form factors for drives used in data centers. EDSFF SSDs are made in six sizes: E1.L (Long) and E1.S (Short), E2.L and E2.S, and E3.L and E3.S. Samsung's NGSFF (also known as M.3 or NF1) form factor competes with EDSFF.

Solid State Drive
A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data Persistence (computer science), persistently, typically using flash memory, and functioning as secondary storage in the Computer data storage#Hierarchy of storage, hierarchy of computer storage. It is also sometimes called a semiconductor storage device, a solid-state device or a solid-state disk, even though SSDs lack the physical spinning hard disk drive platter, disks and movable disk read-and-write head, read–write heads used in hard disk drives (HDDs) and floppy disks. SSD also has rich internal parallelism for data processing. In comparison to hard disk drives and similar electromechanical media which use moving parts, SSDs are typically more resistant to physical shock, run silently, and have higher input/output rates and lower latency (engineering), latency. SSDs store data in semiconductor cells. cells can contain between 1 and 4 Bit (computing), bits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Center
A data center (American English) or data centre (British English)See spelling differences. is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems. Since IT operations are crucial for business continuity, it generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g., air conditioning, fire suppression), and various security devices. A large data center is an industrial-scale operation using as much electricity as a small town. History Data centers have their roots in the huge computer rooms of the 1940s, typified by ENIAC, one of the earliest examples of a data center.Old large computer rooms that housed machines like the U.S. Army's ENIAC, which were developed pre-1960 (1945), were now referred to as "data centers". Early computer systems, complex to operate and ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storage Networking Industry Association
The Storage Networking Industry Association (SNIA) is a registered 501(c)(6) non-profit trade association incorporated in December 1997. SNIA has more than 185 unique members, 2,000 active contributing members and over 50,000 IT end users and storage professionals. The SNIA absorbed the Small Form Factor Committee. SNIA's membership community participates in the following storage-related technical working groups: * Certification * Cloud Storage Technologies * Computational Storage * Data Management * Data Security * Dictionary * Networked Storage * Next Generation Data Center * Persistent Memory * Physical Storage * Power Efficiency Measurement * Storage Management Initiative – Specification (SMI-S) * Storage Management Swordfish Protocol SNIA and its technical council maintain a vendor-neutral dictionary and glossary of storage networking, data, and information management terminology. The SNIA dictionary won an award for publication excellence in 2009 and 2012 from the Bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NGSFF
M.2, pronounced ''m dot two'' and formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and associated connectors. M.2 replaces the mSATA standard, which uses the PCI Express Mini Card physical card layout and connectors. Employing a more flexible physical specification, M.2 allows different module widths and lengths, which, paired with the availability of more advanced Interface (computing), interfacing features, makes M.2 more suitable than mSATA in general for solid-state storage applications, particularly in smaller devices such as ultrabooks and Tablet computer, tablets. Bus (computing), Computer bus interfaces provided through the M.2 connector are PCI Express x4 (up to four PCI Express lane, lanes), Serial ATA 3.0, and USB 3.0 (a single logical port for each of the latter two). It is up to the manufacturer of the M.2 host or module to select which interfaces are to be supported, dependi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NVM Express
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 ...

PCI Express
PCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe or PCI-e, is a high-speed serial computer expansion bus standard, designed to replace the older PCI, PCI-X and AGP bus standards. It is the common motherboard interface for personal computers' graphics cards, hard disk drive host adapters, SSDs, Wi-Fi and Ethernet hardware connections. PCIe has numerous improvements over the older standards, including higher maximum system bus throughput, lower I/O pin count and smaller physical footprint, better performance scaling for bus devices, a more detailed error detection and reporting mechanism (Advanced Error Reporting, AER), and native hot-swap functionality. More recent revisions of the PCIe standard provide hardware support for I/O virtualization. The PCI Express electrical interface is measured by the number of simultaneous lanes. (A lane is a single send/receive line of data. The analogy is a highway with traffic in both directions. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
