LaScala

LaScala is now sold as a component of Sanbolic’s product suites.

LaScala is a host-based volume manager incorporating advanced transaction management, locking, and clustering technology, which simplifies management and improves flexibility and reliability of shared storage environments. Multiple hosts can simultaneously see and administer storage volumes, and volumes can span multiple storage controllers. Assignment of host access to specific shared volumes is easily accomplished with native Windows ACLs. In conjunction with Sanbolic’s shared file system, Melio FS, LaScala provides very high performance shared access to file on volumes striped across large numbers of disks on multiple controllers.

LaScala provides easy-to-use disk management, including online configuration of shared logical volumes. Windows technologies such as Active Directory, ACL security, DFS, Failover Clustering, Network Load Balancing, and MPIO are transparently supported by LaScala across the shared storage environment. RAID 1 is now incorporated into LaScala, providing software mirroring. The configuration operations are fault tolerant by the use of journaling for all operations. LaScala supports native Windows security and allows the use of ACL settings on volume-level security to assign access rights to volumes as shown below:

LaScala is designed for ease of use and is essentially transparent to the user familiar with native OS disk administration tools. Every operation possible with a normal volume is possible with a LaScala volume. Any modifications made to the volume structure are reflected immediately on all computers that are affected by the change. LaScala volumes behave identically in case of hardware failure so any existing software – like file system, backup software, etc. will function normally without modification.

In the Data Center Product Suite, LaScala includes remote management capability that enables customers to remotely manage the volume structure for their entire SAN. It also provides volume and mount point scalability on top of existing LUNs, and support for Windows Volume Management (LDM) volumes.

LaScala remote management can be in used remotely on a laptop or server accessing the SAN through a VPN, or locally on any server on the SAN. Administrators can use LaScala remote management to log into any domain or workgroup on the network, and then manage both volume structure and server access profiles to the storage for all physical or virtual servers connected to the SAN. Administrators use an intuitive WMI-based graphical interface to manage volumes.

LaScala remote management supports and manages all standard LaScala volume management functionality for SAN volumes. This brings simplicity and user friendliness to the SAN management by allowing users to provision volumes and assign them to user accounts on the fly using native Windows security (ACL). LaScala maintains consistent drive letter assignment across the SAN, and supports both NTFS and Sanbolic’s Melio clustered file system. The interface is intuitive to any Administrator familiar with Windows, thus minimizing the learning curve.
