Sistina Software Sistina Software was an organization that focused on storage solutions architected around a Linux platform. They were acquired by Red Hat in December, 2003. Their two primary offerings were Global File System (GFS) and logical volume management (LVM). , the premier storage infrastructure software company delivering data-sharing solutions, today announced the availability of Logical Volume Manager (LVM) 2.0. This newest version of Sistina LVM, which provides increased performance and flexibility with the innovative device-mapper design, will be included as a standard component in the Linux 2.6 kernel. Currently, Sistina LVM 1.0 is the de facto [Latin, In fact.] In fact, in deed, actually.

 volume manager distributed in the 2.4 kernel and used by tens of thousands of end-users worldwide.

Sistina LVM supports enterprise-level volume management of disk and disk subsystems by grouping arbitrary disks into volume groups, which can then be accessed as regular block devices. LVM 2.0 is fully compatible with previous standard LVM versions while providing important high availability features such as transactional replicated metadata (1) (meta-data) Data that describes other data. The term may refer to detailed compilations such as data dictionaries and repositories that provide a substantial amount of information about each data element. . In order to ensure uninterrupted access to the storage, continual availability of the key metadata is an essential component for enterprise users. Sistina LVM also provides ease of management for system administrators and end-users by allowing them to upgrade systems, remove failing disks, reorganize re·or·gan·ize

"Sistina LVM is essential to successful SAN deployment, and overall, for uptime in an environment where storage is dynamic and rapidly growing," said Gudbjorn Hreinsson, technical director for Iceland Telecom. "I have not found any other better solution providing volume management for my Linux environment."

LVM 2.0 Highlights

The newest version of Sistina LVM supports many enhanced features for increased performance and flexibility including:
-- Transactional metadata updates ensure integrity of key volume mapping data

-- User interface and metadata compatible with LVM 1.0 in order to support smooth migration to LVM 2.0

-- Robust Application Program Interface (API) available for use by other storage management applications

-- Device-mapper as the standard Linux mapping service in version 2.6 (soon available in Linux 2.4)

-- Cluster-ready architecture

-- Human readable metadata format eases configuration and maintenance

-- Cleaner integration with the Linux kernel

"Sistina is pleased to be able to share our software developments with the Linux community," stated Matthew O'Keefe, chief technology officer and founder of Sistina Software. "Sistina LVM is a major building block for the Linux OS because it allows Linux to be used in an enterprise server environment, reinforcing our commitment to providing enterprise-level software to the open-source community."

Sistina LVM has received widespread industry praise since first being released into the open-source community. In September 2002, Sistina LVM was honored with a Linux Journal Linux Journal is a monthly magazine published by Belltown Media, Inc. of Houston, Texas. The magazine has been published since March 1994.
