ADDING NEW FEATURES TO CLEVERSAFE (Open source disperse storage network)
Development and team management
The Cleversafe Dispersed Storage Network (dsNet) offers a fundamentally better way to store and retrieve remote data due to availability of broadband internet connections and high speed processors for PC’s. The Cleversafe dsNet uses Information Dispersal Algorithms (IDA’s), which allows forward error correction and recovery. Coding and dispersing information can vastly improve the reliability, security and efficiency of data storage improved over traditional copy- and parity-based systems. Data is written and read using Cauchy-solomon algorithm on the nodes. Using remaining nodes based on nodes threshold can retrieve even loss of any data or nodes, data. Vault is the block device; this can be accessed using iSCSI initiator. This vault starts its own new iSCSI target service and listens on this port. For using this target, needs to stop default target of OS. Then user can access the target.Show More Show Less

CLI OVER SES USING BUFFER POOL MANAGER FOR GEM
Design and firmware development.
In order for GEM to be more flexible, it can extend the GEM feature set to include full CLI support over other transport mechanisms such as SES and TCP/IP.
Buffer pool manager is designed to carry out management of buffers for the CLI commands. When buffers are full while executing a command, command execution is paused and waits for a specified period or buffers are freed. When buffers are freed, execution is again started and finished. SES or TCP/IP or serial port will take care of sending back the data to user in the specified format. The buffer-pool manager and the requirement to serve FIFO-ordered buffers are both fairly straightforward resource tracking tasks. Vendor specific SES page 0x84 and 0x85 implemented,Show More Show Less
