Sun Microsystems, Inc. was an American technology company that sold computers, computer components, software, and information technology services and created the Java programming language, the Solaris operating system, ZFS, the Network File System (NFS), and SPARC microprocessors. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, RISC processors, thin client computing, and virtualized computing. Notable Sun acquisitions include Cray Business Systems Division, Storagetek, and Innotek GmbH, creators of VirtualBox. Sun was founded on February 24, 1982. At its height, the Sun headquarters were in Santa Clara, California, on the former west campus of the Agnews Developmental Center.
A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic-tape data storage is typically used for offline, archival data storage. Tape media generally has a favorable unit cost and a long archival stability.
ESCON is a data connection created by IBM, and is commonly used to connect their mainframe computers to peripheral devices such as disk storage, tape drives and IBM 3270 display controllers. ESCON is an optical fiber, half-duplex, serial interface. It originally operated at a rate of 10 MB/s, which was later increased to 17 MB/s. The current maximum distance is 43 kilometers.
Hierarchical storage management (HSM), also known as Tiered storage, is a data storage and Data management technique that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as solid state drive arrays, are more expensive than slower devices, such as hard disk drives, optical discs and magnetic tape drives. While it would be ideal to have all data available on high-speed devices all the time, this is prohibitively expensive for many organizations. Instead, HSM systems store the bulk of the enterprise's data on slower devices, and then copy data to faster disk drives when needed. The HSM system monitors the way data is used and makes best guesses as to which data can safely be moved to slower devices and which data should stay on the fast devices.
A virtual tape library (VTL) is a data storage virtualization technology used typically for backup and recovery purposes. A VTL presents a storage component as tape libraries or tape drives for use with existing backup software.
In computing, thin provisioning involves using virtualization technology to give the appearance of having more physical resources than are actually available. If a system always has enough resource to simultaneously support all of the virtualized resources, then it is not thin provisioned. The term thin provisioning is applied to disk layer in this article, but could refer to an allocation scheme for any resource. For example, real memory in a computer is typically thin-provisioned to running tasks with some form of address translation technology doing the virtualization. Each task acts as if it has real memory allocated. The sum of the allocated virtual memory assigned to tasks typically exceeds the total of real memory.
Oracle StorageTek SL8500 is an enterprise-class robotic tape library.
Storage Technology Corporation created several magnetic tape data storage formats. These are commonly used with large computer systems, typically in conjunction with a robotic tape library. The most recent format is the T10000. StorageTek primarily competed with IBM in this market, and continued to do so after its acquisition by Sun Microsystems in 2005 and as part of the Sun Microsystems acquisition by Oracle in 2009.
Overland Storage is a wholly owned subsidiary of Sphere 3D Corp. It has acquired Tandberg Data shortly before being acquired by Sphere 3D itself. The two subsidiaries were later rebranded under the common Overland-Tandberg brand.
9-track tape is a format for magnetic-tape data storage, introduced with the IBM System/360 in 1964. The 1⁄2 inch (12.7 mm) wide magnetic tape media and reels have the same size as the earlier IBM 7-track format it replaced, but the new format has eight data tracks and one parity track for a total of nine parallel tracks. Data is stored as 8-bit characters, spanning the full width of the tape. Various recording methods have been employed during its lifetime as tape speed and data density increased, including PE, GCR, and NRZI. Tapes come in various sizes up to 3,600 feet (1,100 m) in length.
The IBM Storage product portfolio includes disk, flash, tape, NAS storage products, storage software and services. IBM's approach is to focus on data management.
The Sun Fire X4500 data server integrates server and storage technologies. It was announced in July, 2006 and is part of the Sun Fire server line from Sun Microsystems.
VMDK is a file format that describes containers for virtual hard disk drives to be used in virtual machines like VMware Workstation or VirtualBox.
The IBM 3570 is a series of tape drives and corresponding magnetic tape data storage media formats developed by IBM. The storage technology and media were introduced using the name Magstar MP, combining the IBM storage brand name Magstar with MP for MultiPurpose. The IBM product number 3570 was associated with the tape drives and libraries that used the Magstar MP media.
The Linear Tape File System (LTFS) is a file system that allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives. It requires both a specific format of data on the tape media and software to provide a file system interface to the data.
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 to large enterprise and government organizations.
NetVault is a set of data protection software developed and supported by Quest Software. NetVault Backup is a backup and recovery software product. It can be used to protect data and software applications in physical and virtual environments from one central management interface. It supports many servers, application platforms, and protocols such as UNIX, Linux, Microsoft Windows, VMware, Microsoft Hyper-V, Oracle, Sybase, Microsoft SQL Server, NDMP, Oracle ACSLS, IBM DAS/ACI, Microsoft Exchange Server, DB2, and Teradata.
Tallgrass Technologies Corporation was an American computer hardware company that was the first to offer a hard disk drive product for the IBM PC in 1981. Tallgrass was a Kansas City based microcomputer hardware and software company founded in December 1980 by David M. Allen. The hard disk drive product was initially sold in Computerland stores, alongside the original IBM PC. Tallgrass added tape-backup systems to its product line in 1982.
Terry Johnson was an engineer and entrepreneur notable for his pioneering work on hard disk drives (HDD). Johnson's early career included engineering and management roles in magnetic recording at IBM (1964–70) and Memorex (1971–73). He then joined in the development of STC 8000 Super Disk, a high-end, rotary actuator HDD funded by StorageTek.
Documation was an American Stock Exchange-listed computer hardware manufacturer founded in 1969 in Melbourne, Florida that went public in 1976. They made card readers used in some American elections 3 decades later. They also produced Impact Line printers.
