Compatibility and certifications
LIO is compatible to Initiators of the following operating systems:
- Microsoft: Windows Server 2003/2008/R2 and Windows XP/Vista/7
- Apple Mac OS X (via third-party initiator)
- Linux: RHEL 4/5/6, SLES 10.3/11, CentOS, Debian, Fedora, openSUSE, Ubuntu
- Unix: Solaris 10, OpenSolaris, HP-UX
- VMs: vSphere 5 (incl. VAAI), Red Hat KVM, Microsoft Hyper-V, Oracle xVM/VirtualBox, Xen
LIO passed vSphere 5 (incl. VAAI) certifications with Buffalo and others. It also passes the Microsoft Windows Server 2008 / R2 Failover Cluster compatibility test suites.
The LIO Unified Target
has been integrated into RTS OS
, a single-node Unified Storage operating system. RTS OS fully supports VMware vSphere
5 including VAAI. Active RTS OS subscriptions
provide access to additional RTS OS packages and update services.
RTS OS is currently being extended into RTS Live, a cluster storage operating system that is based on RTS Director.
LIO is complemented with two management frameworks:
LIO is designed from gound up to support highly available and cluster storage:
- Deeply embedded high availability (Network RAID1)
- Scale-out clusters and disaster recovery solutions
Initiator is a high-end iSCSI Initiator that resolves a number of known issues with the Open-iSCSI
standard Linux Initiator, especially its slow performance.
Core-iSCSI is available on Linux and Windows, and it has been ported to a wide range of platforms and devices, including:
Datera, Inc. ported OCFS2 onto the Nokia Internet Tablets on top of the Core-iSCSI Initiator.
| |RTS Director
is a distributed, highly-available cluster management framework. It comprises a shell, active library and API. The active library and API provide an extensible platform with a unified namespace to manage complex functionality, such as high-availability and cluster striping. The shell offers location-transparent access to all objects in the SAN. New functionality and devices can be added via plugin-modules.
RTS Director provides zero configuration. It is based on a symmetrically distributed architecture - there is no single point of failure, no cluster controller, no central database, etc. Nodes running the RTS Director automatically discover and join the cluster when coming up (demo video).
