The VS category is divided into two grades; VS1 denotes a higher clarity grade than VS2. Typically the inclusions in VS diamonds are invisible without magnification; however, infrequently some VS2 inclusions may still be visible. An example would be on a large emerald cut diamond which has a small inclusion under the corner of the table. [2]
Classifications of these athletes by disability are placed into two categories: VS1 and VS2 formerly D and MD. While VS2 athletes have lost only a fraction of their muscular strength and flexibility in a joint preventing them from successfully playing standing volleyball, VS1 athletes have lost all of their muscular strength and flexibility in ...
It’s also worth noting that participants don’t need to be unable to stand to take part – athletes categorized as VS1 and VS2 (those with a less severe impairment) can play, though only two ...
VSAM was introduced in the 1970s when IBM announced virtual storage operating systems (DOS/VS, OS/VS1 and OS/VS2) for its new System/370 series, as successors of the DOS/360 and OS/360 operating systems running on its System/360 computer series. While backwards compatibility was maintained, the older access methods suffered from performance ...
V-speed designator Description V 1: The speed beyond which takeoff should no longer be aborted (see § V 1 definitions below). [7] [8] [9]V 2: Takeoff safety speed. The speed at which the aircraft may safely climb with one engine inoperative.
OS/VS2 Release 3.8 was the last free release of MVS. In the late seventies and early eighties IBM announced: 5740-XE1 MVS/System Extensions (MVS/SE) MVS/SE improves the performance and RAS of OS/VS2 (MVS) 5740-AM6 Data Facility Device Support (DFDS) for OS/VS1 5740-AM7 Data Facility Device Support (DFDS) for MVS
Logical layout. Each VPLEX engine in a cluster consists of two redundant IO directors and one IO annex, each being a single rack unit (1U) physical device. Each engine has 32 Fibre Channel ports (the VS1 model 16 front-end ports and 16 back-end ports) or 16 Fibre Channel ports (the VS2 model has 8 front-end ports and 8 back-end ports) and is protected by two redundant stand-by power supplies.
OS/VS2 release 1 is an upgrade of OS/360 MVT that retained most of the original code and, like MVT, is mainly written in assembly language. The MVS core is almost entirely written in Assembler XF , although a few modules were written in PL/S , but not the performance-sensitive ones, in particular not the Input/Output Supervisor (IOS).
