RisingTide IP storage software allows non-stop IP Storage systems with a tunable consistency model to deliver optimal performance and availability for a broad range of business requirements, including large-scale desaster recovery configurations. This product leverages Linbit's proven DRBD technology.
Relax. High availability is a crucial factor in today's world of business. RisingTide offers a product and service portfolio designed for you to rest easy knowing your systems will simply run non-stop. With our groundbraking IP storage replication technology and a lineup of availability products and tailored service offerings, we can make your life a lot easier.
Network RAID1
Enterprise Clustering
RisingTide supports transparent failover clustering for Windows Server 2008 and RHEL 5.x, based on full IETF SPC-4 compliance with persistent reservations, ALUA and I/O Fencing.
Protocol-level Redundancy
Protocol-level failover and multipathing further increase availability by minimizing the recovery times for lower-level faults.
Network RAID1
Selectable high availability. RisingTide IP storage software allows fully redundant storage system configurations (active/passive redundancy) with an adjustable consistency model to deliver optimal performance and availability for a broad range of business requirements, including globally distributed desaster recovery configurations. Failover times of less than 3 seconds allow practically continuous operation.
Storage Enterprise Cluster
Full redundancy. RisingTide offers Storage Enterprise Cluster, which delvers highly-available iSCSI, FCoE and FC storage solutions. You can avoid vendor lock-in by using exclusively commercial, off-the-shelf (COTS) hardware components. Our Storage Enterprise cluster leverages Linbit's proven DRBD technology, to form form a tightly integrated product built on Open Source Software components.
Consistency Model
Variable synchronicity. The resulting solution allows to dial-in the consistency and coupling level from synchronous via buffered to asynchronous depending on the distance and latency between the two redundant storage nodes. The resulting system can scale from tightly coupled synchronous storage nodes to globally distributed desaster recovery solutions.
Summary
- Active/passive redundancy and failover.
- Storage node pairing is completely contained in iSCSI, FCoE and FC target.
- Tunable consistency model to select performance/availability tradeoff.
Enterprise Clustering and Failover
Enterprise clustering with open-source pricing. By combining proven IP storage technology with commodity storage arrays, a growing organization can take advantage of an advanced feature set that provides reliable data protection and improved availability at the lowest cost for a wide range of operating environments.
Failover Clustering
Clustering for Windows Server 2008 and RedHat RHEL 5.x RisingTide IP storage transparently supports protocol-level redundancy and failover clustering for Windows Server 2008 and RedHat Enterprise Release 5x. These capabilities are based on advanced features like Persistent Reservations (PR), Assymmteric Logical Unit Assignment (ALUA) and I/O Fencing that are otherwise only available in very expensive high-end storage arrays. A number of these features are implemented independently of the underlying fabric and hence can work seamlessly across multiple protocols, such as iSCSI, FCoE and FC.
Summary
- High-end end storage features like Persistent Reservations, ALUA and I/O Fencing.
- No single point of failure within either logical or physical connections.
Protocol-Level Redundancy
Increased end-to-end availability. Protocol-level failover via Multipathing, MC/S and ERL=2 further increase end-to-end performance, resiliency and availability by minimizing the recovery times from lower-level faults. There is no other open-source iSCSI, FCoE and FC target that has similarly hardened support for these advanced features.
Summary
- Full redundancy within iSCSI, FcoE and FC protocol layer.
- Multipathing over multiple subnets.
- Multiple Connections per Session (MC/S) over multiple subnets.
- Full Error Recovery (ERL=0,1,2) for iSCSI inititor and target.
- Active/active session continuation.
- Trunking within iSCSI, FCoE and FC layer.
- Aggregation of the entire available bandwidth.
Powerful and Easy High-Availability Management
Architected from ground up for High-Availability. The basic CLI and API concepts (cluster-wide storage object tree, symmetric scale-out, and smart syntactic and semantic sugar) seamlessly extend to high availability. A storage node can be made highly available by simply specifying the IP address of its secondary. The library then automatically pairs the two nodes and provides a virtual IP address for the resulting highly available array.
Summary
- High availability is deeply embedded into the stack and the management interface.
- The CLI/API concepts seamlessly extend to HA, making HA simple and straightforward.
