The Kaminario Scale-out Performance Storage Architecture (SPEAR) is a fundamentally new and better way to store and retrieve performance-sensitive data. The Kaminario K2 all Flash SSD array is the first enterprise-grade, general purpose storage array built from the ground up to take full advantage of modern Flash SSD performance, while shielding customers from Flash wear-leveling and poor write performance. The K2's modular scale-out architecture, the K2 SPEAR Storage operating system (OS) consistently delivers ultra-low latency, tens of GB/s of throughput and millions of IOPS at less than the cost of legacy SAN storage. Its built-in, DataProtect with self-healing high availability, Flash resiliency and data protection with snapshots, provides enterprise-class reliability to reduce downtime and the K2's hot-swappable components and undisruptive code upgrades reduce operational expenses.
The fundamental SPEAR software capabilities include the following:
Intelligent Parallel IO Processing — I/O requests are distributed across the K2 storage cluster, smartly parallelizing all reads and writes over multiple K-nodes. This achieves low latency, shortening the average response time of I/O requests and increasing the rate of I/O request processing, which provides an advantage over other arrays: it does not lose the ability to sustain high throughput.
DataProtect Self-Healing High Availability and Fast Data Protection — SPEAR is designed to maintain data availability through any type of failure. N+1 availability is built in to the hardware, but it is the SPEAR Storage OS with DataProtect that detects the failures, initiates the self-healing process and manages the dynamic cluster reconfiguration in the event of a failure. DataProtect assures self-healing high availability and fast, high-volume data protection for backup and disaster recovery, while delivering extreme storage performance to mission-critical applications.
Enhanced Flash Endurance — SPEAR minimizes writes to the Flash media and maximizes Flash endurance. It utilizes a system-wide write cache that eliminates hotspots and it distributes writes across all Flash media in the system, thus sustaining global wear leveling. With SPEAR's abilities, Kaminario has a warranty of seven years for Flash endurance.
Nondisruptive Upgrades — SPEAR facilitates code upgrades to its OS, including upgrades of BIOS, firmware and patches to any of the Kaminario K2 components. The upgrade process occurs while the system is online, with little to no impact on performance.
Kaminario Management Service (KMS) — SPEAR provides a single management service across all K-blocks in the K2 system. The KMS controls the K2 system, orchestrating and monitoring various system-wide tasks. The process is highly available at all times and automatically reconfigures itself as the system scales in order to manage the growing configurations.
Automated Data Distribution — Following an expansion, SPEAR automatically performs a rebalancing process, after which the system regains full scale-out performance. During this operation, both data and metadata are redistributed from existing DSSs to new DSSs, balancing the load easily and effortlessly.
SPEAR Technology Design
Each K-Block houses multiple K-Nodes that provide connectivity, data management, high availability and protection, and MLC Flash SSD storage
The K2 delivers a superior and consistent experience of sub-millisecond latency and millions of IOPS within any virtualization environment. K2 provides consistent, high performance services under any form of load for virtual environments using VMFS or Raw Device Mapping. Applications can vary and include OLTP, OLAP, data warehouse, big data analytics and VDI.
Kaminario fully supports the relevant VAAI primitives to accelerate, offload and expedite important hypervisor tasks and allows tens of thousands of virtualized machines to operate quickly and efficiently. Learn more about the K2's integration with virtual environments.
Kaminario K2 hardware is based on industry-standard enterprise hardware. The Kaminario K2 does not utilize any proprietary hardware components. This approach allows for the quick adoption of new, best-of-breed technology as it becomes available in the market. With the SPEAR design, deployment of the K2 is transparent to applications and databases, enabling fast installation-to-operation (typically less than one day). The system uses an N+1 redundant architecture with no single point of failure. In the event of a hardware failure, there is at least one redundant component that can compensate for the loss of the failed component.
