lot of memory as its cache space, on the Exchange Server system with more than 300 users, The physical memory consumption of the Store.exe process is generally above 1GB. In the Windows operating system, memory is divided into physical memory and virtual memory. Physical memory refers to the memory that is installed on the machine, and virtual memory refers to the range of memory that the CPU can address. For Windows 2000来, the size of physical memor

Raid0~raid7, common raid types are RAID0, RAID1, Raid5,raid10. In addition, depending on how they are connected, they can also be divided into: Direct attached Storage (DAS), Storage area Networks (SAN), Fibre Channel and Storage area NETWORKS,ISCSI Storage area Networks. Throughput and IOPS Metrics Throughput depends primarily on the schema of the array, the size of the fibre Channel, and the number of hard drives. The architecture of the array is different from each array, but there is als

We sometimes need to through the network to some friends or netizens, to provide some file downloads, we will install an FTP server software on the computer and then create a temporary FTP directory to facilitate their access to download files, after the download, then close the service can be. Actually, as long as you use QQ, then you can put the need to share the file to the QQ file transfer Station to provide free 1GB storage space, and then to nee

Recently, foreign devilmountain software companies in memory 1GB and memory 2GB hardware configuration of the Vista SP1 running speed test, but the results found that the system does not seem to have changed too much. This makes many users feel a bit of a surprise. SP1 failed to improve Vista speed It is understood that the test is using Vista SP1 RC1 version, dual-core processor, independent graphics, memory used

virtual machine Port Group is a set of virtual switch ports that share a set of identical configurations that allow virtual machines to access other virtual machines configured on the same port group, accessible Pvlan, or on a physical network.6, virtual LAN, virtual or physical switch configured on the logical LAN, can provide efficient traffic segmentation, broadcast control and security, only for specific VLAN configuration port transport traffic.7, Trunk Port , is the physical switch port,

Although some people have proposed ways to increase SFP signal strength physically, use the SAN over SONET (SDH) method to enhance Remote Disaster Tolerance over 100 kilometers) Data Transmission Performance, however, this further increases the deployment cost of the disaster recovery solution. In a remote disaster recovery system, data transmission over the IP protocol is the cheapest data transmission method. This technology can a

The current 24-port full-Gigabit Switch market is in great competition, some may not know the forwarding Performance Test and line congestion test of 24 full gigabit switches. After reading the following articles, you will become an expert. 2-layer Competition Layer 2 performance tests include forwarding performance, port congestion control, address learning rate, Address Table depth, error frame Filtering, broadca

, all functional modules (such as the super engine module, IP voice module, extended service module, network monitoring module, and security service module) need to occupy one slot, therefore, the number of slots fundamentally determines the scalability of the switch. 2. module type. Undoubtedly, the more supported module types (such as LAN interface module, WAN interface module, ATM interface module, and extended function module), the more scalable the switch. Taking LAN interface module as an

There are many points worth learning about the gigabit network management switch. Here we mainly introduce the basic principles of the gigabit network management switch. NETEGAR's Fast Ethernet and 1-gigabit Network Management Switch have maximum throughput and flexibility-as a high-speed, high-density Working Group access on the edge of the network, as the central backbone switching device of a growing commercial network, or applications that require high-speed connections between files with hi

meet high-speed bandwidth needs, such as 10 GB Ethernet and 16 GB optical fiber channels. The industry is upgrading the OM3 and OM4 light green optical fiber cables to 50 micron for long-distance connections. OM4 is ideal for horizontal cabling and inter-IDC cabling, whether for Ethernet or fiber channel. "If you are using multimode optical fiber, you should purchase OM4," Martin said. "The reason why OM4 is recommended is that it can be used for both 40g and G Ethernet, but also for high-spe

The release of the stackable switch standard in the industry has become a new highlight. After the popularization of broadband, the standard of Stackable switches will often face problems. So today, I am going to introduce you to the stackable switch standard. I hope this article will teach you more things and bring convenience to your life. BayStack 5510 defines the next generation of Stackable switch standards. Stackable switch Standard ◆ Provides up to 384 gigabit-to-desktop interfaces a
