    Aggregate and connect access switches for users into aggregation switches and within the data center to achieve a high availability, high performance data center infrastructure. This article looks at what each such tool does, compares how they differ from each other, and offers suggestions as to what sort of network each. When selecting an aggregation switch, several critical factors must be considered to ensure optimal performance. These factors may include but are not limited to speed, features, and price. The Pro Aggregation does this with it's SFP28 25Gbps ports. The regular Aggregation switch is best used to connect all devices in a rack. Switch aggregation, also known as link aggregation or trunking, is a method used in computer networking to combine (aggregate) multiple network connections in parallel.


  • Can a KVM switch be used with an all-in-one machine

    Can a KVM switch be used with an all-in-one machine

    KVM switches are called KVM sharing devices because two or more computers can share a single set of KVM peripherals. Computer sharing devices function in reverse compared to KVM switches; that is, a single PC can be shared by multiple monitors, keyboards, and mice. A computer sharing device is sometimes referred to as a or reverse KVM switch. While not as common, this configuration is useful when the operator wants to access a single computer from two or more (usually close) locatio.
