Double-Take Aims to Improve Availability of Linux Workloads

Double-Take Software, a provider of workload optimization products, has announced the availability of a new release of Double-Take for Linux (version 4.5) that enables customers to protect the availability of Linux-based IT workloads without requiring specialized or proprietary hardware and storage-based availability solutions.

This latest version offers extended distribution support for Novell SUSE Linux Enterprise Server 10 and CentOS 4 and 5. Double-Take Software plans to add support for the recently released Novell SLES 11 in its next service pack, due out this month, while also continuing to offer support for Red Hat Enterprise Linux 4 and 5.

Version 4.5 also adds disk block-level replication to its current file byte-level capabilities, providing users the flexibility of using either block- or byte-level replication, depending on the application and workload in need of protection. The new version of Double-Take enables customers to protect data residing on additional file systems and within applications that leverage raw disk modes.

Double-Take also provides users with support for ReiserFS, an additional option for protection of block-based data, and support for and the ability to run Xen para-virtualized kernels. Double-Take for Linux also now offers two types of data replication, and provides customers disaster recovery solutions that are flexible and easy to use, according to Bob Roudebush, director of solutions engineering at Double-Take Software. "What we are able to do is provide customers for the first time with a software-based availability tool that will do both byte-level file replication, which is traditionally what we have done and what we do in Windows on the other side of the fence, but also this block-level replication and support for raw partitions," Roudebush explains.
