In the course IST 651 – Scripting for Enterprise Data Systems, iSchool Professor Carlos Caicedo introduced us to system and network infrastructure automation concepts and a tool called Ansible. This was the first time we became familiar with Ansible and how powerful it can be for automating system and network configuration management tasks.
As the new 802.11 ac Wave 2 products are knocking on the door of the wireless industry, it caused a confusion on how the typical network infrastructure of Ethernet switches supporting 1 Gbps of traffic on ports going to cope with the overwhelming super-fast data rates of Wave 2 products (up to 7 Gbps). The other major problem which kicks in is that nearly 46% of the cabling in the enterprises are CAT5e standard which currently support upto 1 Gbps speed up to 100 meters. These all issues leads to a bottleneck situation which will be created on the wired side of the network. Continue Reading
As businesses and critical applications are becoming dependent on WLAN network, there is need to be on toes always to resolve the day to day issues which comes in WLAN. The tools used by network technicians to troubleshoot WLAN, don’t offer the full capabilities. According to Fluke networks, the functions of various tools are converged into one testing product called AirCheck. AirCheck is currently available in windows version and will soon be available for android(they didn’t say anything about IOS). It supports 802.11 a/b/g/n and ac devices. This software tool has intuitive interface and it provides an instant real-time view of the Wi-Fi environment including network availability, utilization, security settings and rogue devices to troubleshoot most common Wi-Fi issues. AirCheck has following features :
Storage Area Network (SAN) is a collection of computers and storage devices, connected over a high-speed optical network and dedicated to the task of storing and protecting data. SANs support disk mirroring, backup and restore, archival and retrieval of archived data, data migration from one storage device to another and the sharing of data among different servers in a network. SAN uses a fibre channel for the communication between the devices. Devices in a SAN are usually bunched closely together in a single room, but the network allows the devices to be connected over long distances.

What is IPv6?
IPv6 appeared as a protocol designed to overcome some of the inherent issues in IPv4. Since the protocol was developed taking into account improvements needed for IPv4, such as security, one could think that IPv6 and its new set of features are a glass of water for someone in the middle of desert. IPv6 include several security improvement next to IPv4. IPsec, for example, is a gold star that creates expectations regarding embedded privacy, authentication, and authorization. The possibility of having encrypted communications over almost any network is as promising as the idea of having enough IP addresses available not to have to worry about VLSM anymore.
