Snapshot
Snapshot – A virtual copy of a file or RAID volume or object at a point in time created in a database, hypervisor, file system or storage system that relies...
COW
COW - Copy-on-Write. See snapshot entry.
Compression
Compression - the shrinking of a file or object’s size by replacing repeated strings of bits with fewer bits and a pointer. This is done so that files take...
CXL
CXL – Computer eXpress Link – the extension of the PCIe bus outside a server’s chassis, based on the PCIe 5.0 standard. There are five successive versions of the standard;
CXL v1,...
Computational Storage
Computational Storage – A storage drive with computational facilities in the drive and used for working directly on the data stored in the drive. The aim is to reduce data movement...
Composable Systems
Composable Systems – These dynamically compose servers from separate pools of base server (CPU+DRAM) nodes, GPUs and other accelerators, NVMe storage, Optane SSDs and network interface cards. These servers are...
CMOS
CMOS - Complementary Metal-Oxide-Semiconductor. This is a fabrication technology for transistors used in the construction of integrated circuit (IC) chips, such as microcontroller, microprocessors, DRAM and NAND memory chips,...
CIFS
CIFS - Common Internet File System, pronounced 'sifs'. This is a Windows filesystem SMB (Server Message Block) dialect. The CIFS implementation of SMB is rarely used these days and...
Charge Trap
Charge Trap - Charge Trap transistors use an insulator, silicon nitride film, to store electrons in localized traps in a NAND or NOR cell. This is in contrast to NAND and...
CBA
CBA - CMOS directly Bonded to Array. In this NAND technology each CMOS control wafer and cell array wafer are manufactured separately and then bonded together to deliver, Kioxia...
CAS
CAS - Content Addressing System. A data item's contents are binary numbers. They can be mathematically manipulated by a cryptographic function to provide a hash or key, a...
Cache
Cache - A high-speed memory device that is faster than the memory or storage device otherwise used. For example, main memory can be used to cache data from SSDs...
