Is automating analysis of networks beneficial? – By Aditya Abeysinghe What is a network analyzer? A network analyzer is a device that is used to analyze a network. This device can be used to gather information on protocols or networks used, signal strength of a network etc. The method in which a network analyzer analysis networks is by measuring the response of a network’s devices. The network analyzer sends network signals to devices and then a user can see how these devices respond back to these signals in a radio frequency (RF) circuit. The two mostly used types of network analyzers are scalar network analyzers, which measure the amplitude of a radio frequency device, and vector network analyzers, which measure amplitude, phase and other values. Limitations of hardware network devices The main drawback of using hardware devices is that scalability is impossible without wiring new devices with the analyzer. A ...

Software defined storage: A trend for virtualizing data storage? By Aditya Abeysinghe Software defined storage (SDS) is a storage model that separates software used in storage media from the hardware. SDS uses software that controls the hardware and network resources used in data storages. This allows storage to be added or removed without depending on the hardware. The main benefit of this model is flexible storage and maintenance of storage in devices using software. The methodology used Different types of SDSs exist and the methodology used depends usually on the type. A type of SDS is storage virtualization. In this type, a hardware-based storage is used and software is used to virtualize this storage such that it can be used by different processes and monitored centrally. Using virtualization, SDS creates virtual disks which are shown as different storage units within the same hardware storage. This method will also use management ...
