SAN BRIDGES AND ISCSI – Improving Block Level Access & Throughput


We often get asked what the difference is between NAS and SAN and how iSCSI protocals can improve access and throughput. Therefore, let’s first review a few basics about NAS (Network Attached Storage) and SAN (Storage Area Networks).

Which Network is Right For Your Organization?

NAS or Network Attached Storage is a file-level (as opposed to block-level storage) computer data storage server. It is connected to a computer network providing data access to a heterogeneous group of clients. NAS is specialized for serving files either by its hardware, software, or configuration.

SAN or Storage Area Network is a dedicated, high-speed network that provides access to block-level storage. SANs were adopted to improve application availability and performance by segregating storage traffic from the rest of the LAN. SANs are primarily used to access storage devices, such as disk arrays and tape libraries from servers. Devices appear to the operating system as direct-attached storage. SAN typically is a dedicated network of storage devices not accessible through local area networks (LAN).

iSCSI or Internet Small Computer System Interface is a block protocol for storage networking. It runs the very common SCSI storage protocol across a network connection which is usually Ethernet. iSCSI, like Fibre Channel, can be used to create a Storage Area Network (SAN). iSCSI traffic can be run over a shared network or a dedicated storage network.

Block Storage, sometimes referred to as block-level storage, is a technology that is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. Block storage breaks up data into blocks and then stores those blocks as separate pieces, each with a unique identifier.

File Storage – also called file-level or file-based storage – is a hierarchical storage methodology used to organize and store data on a computer hard drive or on network-attached storage (NAS) device.

Recognized by Gartner, Bridgeworks’ WANrockIT patented technology approaches WAN performance
inhibitors in a way that uses the safe, tradition TCP/IP protocol. We also combine deep learning AI managed mitigation techniques that can result in performance gains in excess of 200X or up to 98% of available bandwidth. This is applicable to all data types including encrypted, without changing or manipulating the data. WANrockIT optimizes the flow of data across the SAN and the WAN in real time, even if network conditions change. By incorporating a number of artificial intelligence (AI) engines that continuously manage, control and configure multiple aspects of the WANrockIT – your data flow operates optimally at all times without Administrator intervention.
