Bus-Tech Adds SAN Clustering

Arthur Cole

Enterprises using the Bus-Tech Mainframe Data Library (MDL) tape-on-disk controller with their IBM iron have gotten used to the redundancy and high-availability the system provides for IP-based storage and disaster recovery operations. Now, the company is extending that same level of connectivity to clustered SAN environments.

 

The latest version of the MDL platform provides two Fibre Channel ports on each MDL Emulation Node, the independent disk controllers that provide redundant access to open storage systems. With two FC ports, attached disks can now be shared across multiple nodes, bringing the speed and security of SAN connectivity to the system.

 

The Emulation Nodes still provide 2 FICON or ESCON channel interfaces directly to the mainframe and can scale up to more than 1,000 emulated tape drives. For remote backup purposes, the system uses IP-based replication to multiple sites without specialized channel extension, tape duplexing or offsite shipping.

 

MDL versions with SAN clustering support will be available in November.
