FlashSystem
IBM FlashSystem is an IBM Storage enterprise system that stores data on flash memory. Unlike storage systems that use standard solid-state drives, IBM FlashSystem products incorporate custom hardware based on technology from the 2012 IBM acquisition of Texas Memory Systems. According to Gartner, IBM was the number one all-flash storage array vendor in 2014 selling over 2,100 FlashSystems totaling 62 petabytes (PB) of capacity. The IBM FlashSystem commanded 33% of the total all-flash capacity sold by all vendors for the year. As of February 12, 2020 the FlashSystem brand has replaced both the Storwize and XIV brands in IBM. History Origin The IBM FlashSystem architecture was originally developed by Texas Memory Systems (TMS) as their RamSan product line. TMS was a small private company founded in 1978 and based in Houston, Texas that supplied solid-state drive products to the market longer than any other company. The TMS RamSan line of enterprise solid state storage p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flash Core Module
IBM FlashCore Modules (FCM) are solid state technology computer data storage modules using PCI Express attachment and the NVMe command set. The raw storage capacities are 4.8 TB, 9.6 TB, 19.2 TB and 38.4 TB. The FlashCore modules support hardware self-encryption and real-time inline hardware data compression without performance impact. They are used in selected arrays from the IBM FlashSystem family. History On September 17, 2007, Texas Memory Systems (TMS) announced the RamSan-500, the world's first enterprise-class flash-based solid state disk (SSD). The Flash Modules were designed from the ground up by Texas Memory Systems using proprietary form-factors, physical connectivity, hard-decision ECC algorithm, and flash translation layer (FTL) contained completely inside the SSD. The flash controllers used a hardware only data path that enabled lower latency than any other commodity controllers could achieve. This product marked the beginning of development of the RamSan All ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IBM SAN Volume Controller
The IBM SAN Volume Controller (SVC) is a block storage virtualization appliance that belongs to the IBM System Storage product family. SVC implements an indirection, or "virtualization", layer in a Fibre Channel storage area network (SAN). Architecture The IBM 2145 SAN Volume Controller (SVC) is an inline virtualization or "gateway" device. It logically sits between hosts and storage arrays, presenting itself to hosts as the storage provider (target) and presenting itself to storage arrays as one big host. SVC is physically attached to one or several SAN fabrics. The virtualization approach allows for non-disruptive replacements of any part in the storage infrastructure, including the SVC devices themselves. It also aims at simplifying compatibility requirements in strongly heterogeneous server and storage landscapes. All advanced functions are therefore implemented in the virtualization layer, which allows switching storage array vendors without impact. Finally, spreading an S ...

Texas Memory Systems
Texas Memory Systems, Inc. (TMS) was an American corporation that designed and manufactured solid-state disks (SSDs) and digital signal processors (DSPs). TMS was founded in 1978 and that same year introduced their first solid-state drive, followed by their first digital signal processor. In 2000 they introduced the RamSan line of SSDs. Based in Houston, Texas, they supply these two product categories (directly as well as OEM and reseller partners) to large enterprise and government organizations. TMS has been supplying SSD products to the market longer than any other company. On August 16, 2012, IBM Corporation announced a definitive agreement to acquire Texas Memory Systems, Inc. This acquisition was completed as planned on October 1, 2012. History TMS was founded in 1978 in Houston, Texas by Holly Frost to address a need in seismic processing for the oil and gas industry. The company's first product, the CMPS was a 16 Kilobyte (KB) custom SSD designed for Gulf Oil. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM XIV Storage System
The IBM XIV Storage System was a line of cabinet-size disk storage servers. The system is a collection of modules, each of which is an independent computer with its own memory, interconnections, disk drives, and other subcomponents, laid out in a grid and connected together in parallel using either InfiniBand (third generation systems) or Ethernet (second generation systems) connections. Each module has an x86 CPU and runs a software platform consisting largely of a modified Linux kernel and other open source software. Description Traditional storage systems distribute a volume across a subset of disk drives in a clustered fashion. The XIV storage system distributes volumes across all modules in 1 MiB chunks (partitions) so that all of the modules' resources are used evenly. For robustness, each logical partition is stored in at least two copies on separate modules, so that if a part of a disk drive, an entire disk drive, or an entire module fails, the data is still available ...

IOPS
Input/output operations per second (IOPS, pronounced ''eye-ops'') is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN). Like benchmarks, IOPS numbers published by storage device manufacturers do not directly relate to real-world application performance. Background To meaningfully describe the performance characteristics of any storage device, it is necessary to specify a minimum of three metrics simultaneously: IOPS, response time, and (application) workload. Absent simultaneous specifications of response-time and workload, IOPS are essentially meaningless. In isolation, IOPS can be considered analogous to "revolutions per minute" of an automobile engine i.e. an engine capable of spinning at 10,000 RPMs with its transmission in neutral does not convey anything of value, however an engine capable of developing specified torque and horsepower at a given number ...

Solid-state Drives
A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the 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 disks and movable 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. SSDs store data in semiconductor cells. cells can contain between 1 and 4 bits of data. SSD storage devices vary in their properties according to the number of bits stored in each cell, with single-bit cells ("Single Level Cells" or "SLC") ...

RAID 5
In computer storage, the standard RAID levels comprise a basic set of RAID ("redundant array of independent disks" or "redundant array of inexpensive disks") configurations that employ the techniques of striping, mirroring, or parity to create large reliable data stores from multiple general-purpose computer hard disk drives (HDDs). The most common types are RAID 0 (striping), RAID 1 (mirroring) and its variants, RAID 5 (distributed parity), and RAID 6 (dual parity). Multiple RAID levels can also be combined or ''nested'', for instance RAID 10 (striping of mirrors) or RAID 01 (mirroring stripe sets). RAID levels and their associated data formats are standardized by the Storage Networking Industry Association (SNIA) in the Common RAID Disk Drive Format (DDF) standard. The numerical values only serve as identifiers and do not signify performance, reliability, generation, or any other metric. While most RAID levels can provide good protection against an ...

Benchmark (computing)
In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative Computer performance, performance of an object, normally by running a number of standard Software performance testing, tests and trials against it. The term ''benchmark'' is also commonly utilized for the purposes of elaborately designed benchmarking programs themselves. Benchmarking is usually associated with assessing performance characteristics of computer hardware, for example, the floating point operation performance of a Central processing unit, CPU, but there are circumstances when the technique is also applicable to software. Software benchmarks are, for example, run against compilers or database management systems (DBMS). Benchmarks provide a method of comparing the performance of various subsystems across different chip/system Computer architecture, architectures.
