Network Attached Storage (NAS) Network Attached Storage (NAS) devices are storage arrays or gateways that support file-based storage protocols such as NFS and CiFS, and are typically connected via an IP network. These file-based protocols provide clients shared access to storage resources. This centralization of shared storage resources reduces management complexity, minimizes stranded disk capacity, improves storage utilization rates and eliminates file server sprawl. Benefits of NAS NAS devices typically leverage existing IP networks for connectivity, enabling companies to reduce the price of entry for access to shared storage. The RAID and clustering capabilities inherent to modern enterprise NAS devices…

Storage Area Networks Storage Area Networks (SAN) are a separate computer network typically based on a fabric of fiber channel switches and hubs, connecting storage subsystems to a heterogeneous set of servers on an any-server-to-any-server basis. A SAN enables direct storage-to-storage inter-connectivity and lends itself to taking advantage of new types of clustering technology. Storage Area Network benefits include the following: Promotes high availability Improves data storage management and reduces costs Enables efficient hardware deployment and utilization Improves data backup efficiency and accessibility Enables storage virtualization Creating a Storage Area Network Thousands of companies have internally justified the value of…

SAN vs NAS SAN vs NAS, The primary difference between SAN and NAS solutions is the type of access protocol. NAS protocols such as NFS and CiFS provide shared file level access to storage resources. The management of the file system resides with the NAS device. SAN protocols such as iSCSI and fibre channel (FC) provide block level access to storage resources. Block level devices are accessed by servers via the SAN, and the servers manage the file system. Despite their differences, SAN and NAS are not mutually exclusive, and may be combined in multi-protocol or unified storage arrays, offering both file-level…

Just in case you missed the news, National Assembly yesterday passed the cyber crime bill that is going to become a law once it’s approved by Senate and then authorized by President of Pakistan. At this point, when there are new laws relating to internet, smartphones and overall web, it is extremely important for you to know them or you can land yourself into a horrific situation unintentionally or out of ignorance. Read following carefully: Unauthorized access to anyone’s phone, laptop etc. can put you behind the bars for three months or a fine of Rs. 50,000 imposed or both Unauthorized copying…

Switches are very popular as a layer two device whereas a router is very famous for being a layer three device. So, what is that something special that makes router the most popular layer three device? We will take a look at all the differences and functional aspects of a switch and a router Let’s take a look: Switch vs Router — Comparison and differences Switch’s properties: Works at the Data link layer of the OSI layer Uses ‘filter and forwarding’ when it receives a data packet in form of a frame A virtual LAN can be created using a…
