Compatibility and certifications
LIO is compatible to Initiators on the following operating systems:
- Microsoft: Windows Server 2003/2008/R2, Windows XP/Vista/7
- Apple Mac OS X Leopard (via 3rd party initiator)
- Linux: RHEL 4.x/5.x, SLES 10.3/11, CentOS, Debian, Ubuntu

also provides Core-iSCSI
, a high-end iSCSI Initiator, in order to address a number of known issues with the Open-iSCSI
standard Linux Initiator.
Core-iSCSI is available on Linux and Windows, and it has been ported to a wide range of platforms and devices, including:
RisingTide ported OCFS2 onto the Nokia Internet Tablets on top of the Core-iSCSI Initiator.
LIO is from gound up designed to provide excellent integration with high-availability and cluster scale-out.
- Deeply embedded high availability (Network RAID1)
- Scale-out clusters via concatenating LUNs
- Scale-out clusters via striping (1H2011)
LIO is complemented with three levels of comprehensive management tools and frameworks:
| |RisingTide Systems
also provides RTS Director
, a distributed, highly-available cluster management tool. It comprises a shell, active library and API. The active library and API provide an open, extensible platform with a unified namespace that manages complex functionality, such as high-availability and cluster striping. The shell offers location-transparent access to all objects in the SAN cluster. New functionality and devices can be added via plugin-modules.
The RTS Director provides true zero configuration. It is based on a fully symmetric, distributed architecture - there is no single point of failure, no cluster controller, no resource manager, no central database, etc. Nodes running the RTS Director automatically discover and join the cluster when coming up (including the first time).
The RTS Director will be available in December 2010.
