Workstation features

CPU: In the early 80's, RISC architecture processors offered several orders of magnitude higher performance per unit of cost than CISC processors. It was during this period that the family of CISC processors (Intel's x86) gradually gained market share. By the mid-nineties, Intel's CPU finally had the same performance as RISC (though at the cost of much higher chip complexity) and drove the latter into a narrow market.
In the current Intel Xeon processor series, dedicated CPUs designed for servers and workstations have several different architectures and unparalleled processing power. The outstanding feature is the integration of the QPI memory controller. The data communication between the memory and the CPU no longer passes through the North Bridge control chip, breaking the bottleneck of data exchange before the CPU and memory. With the popularity of Intel's 32nm technology, Intel Xeon quad-core or six-core with its powerful computing capabilities become the current choice of server / workstation CPU.
High speed network connection (1000 Mbit/s or higher): Today's workstation integration is basically a 1000Mbit network card
Large-screen display: Traditional CRTs and ordinary liquid crystals are increasingly unable to meet the needs of professional graphics processing and analog simulation in color and screen resolution. High-end professional displays such as the DELL U2410 have become mainstream.
High-performance 3D graphics hardware: Workstations are largely combined with graphics software. OPENGL4.1 and DIRECT 11 have been developed in current software. Only previous versions of professional graphics cards and non-professional game graphics cards have been gradually supported. Unable to meet. Recently, mainstream professional graphics cards include the Leadtek series Q600, Q2000, Q4000, Q5000, Q6000 and ATI's V8800 and V9800.
Disk redundancy storage: Generally speaking, it is RAID. The 90s has never been popular in the PC market. SCSI is an advanced control interface. It is especially effective in situations where disks need to receive multiple access requests at the same time. This makes it suitable for use in servers, but this feature has no advantage over desktop PCs, which are mostly single-user operating systems. Currently, the desktop system gains more multi-user capabilities (due to the increase in the number of Linux), the new disk interface SATA has a similar SCSI speed and lower cost, and the newer generation of SAS hard disks has a faster speed. The redundant array is currently a storage array in which multiple SATA hard disks are configured in different RAID modes. RAID 0 1 5 6 10 is commonly used. In addition to RAID 0, three or more hard disks are required in other modes. The benefits of disk arrays are twofold: A increases the disk access speed by a factor of several times; B ensures data security, one or more disks are corrupted, and disks can be reconfigured after RAID replacement.
