Kaminario releases the fourth generation of K2 flash storage systems

Summary:Virtualized environments can put a strain on the storage system because they use storage differently than physical systems. This generation of Kaminario K2 represents the newest effort to address these changing requirements.

Kaminairo just released the fourth generation of its K2 storage server. Each release has offered better scale-out performance and, at the time, pushed the performance, scalability, and resiliency of hybrid and flash-only storage systems. This time, an all-flash storage version of the K2 has been released to increase levels of throughput and reduce latency while maintaining compatibility with its other systems.

What Kaminario has to say about the fourth generation of K2

Today's legacy storage architectures are 20 years old. Outdated spinning disk architectures can't handle today's 100 percent storage growth per year without driving up costs significantly. Enterprises are especially challenged, as business-critical application workloads are expected to grow 70 percent over the next four years. Current scale-up and stack-up SSD architectures compromise latency, bandwidth, and consistency in performance for capacity. Only the K2 v4 can linearly grow capacity without degrading the performance of bandwidth, latency, or IOPS and, at the same time, provide the resiliency required by enterprises.

Kaminario K2 v4 specific enhancements include:

  • Consistently high performance: 400 percent more read/write bandwidth than previous versions with consistently low latency (120 microsecond writes) and industry-leading IOPS for any mixed workloads.

  • Lower TCO: K2 provides a 500 percent density increase over previous versions and is now offered at half the price.

  • Safety and reliability: Non-disruptive upgrades, guaranteed performance under any failure with minimal impact (usually under 10 percent), hot swappable SAS drives and patent-pending high performance, space-efficient snapshot technology provide consistent enterprise-class SLAs.

  • Expanded support for general purpose, server, and desktop virtualization (VDI) environments such as VMware VAAI, OpenStack cloud computing and RESTful APIs. Customer's choice of iSCSI and Fibre Channel connections.

Kaminario SPEAR

One of the most important elements of the Kaminario K2 family is its storage virtualization software technology. The Kaminario Scale-out Performance Storage Architecture (SPEAR) enfolds storage elements in a very clever and intelligent environment that does a number of things to improve storage utilization and performance. Here are a few of the many software capabilities of SPEAR:

  • Parallel I/O processing — I/O requests coming from systems and workloads are efficiently distributed across the K2 storage cluster. All reads and writes are spread over multiple storage nodes to reduce latency and response, while at the same time increasing both the rate of I/O processing and throughput.

  • DataProtect Self-Healing High Availability and Fast Data Protection — SPEAR is designed to support the intelligent fail/over capabilities of the K2 hardware. This technology detects failures, initiates the self-healing process and manages the dynamic cluster reconfiguration when needed.

  • 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.

SPEAR is designed to facilitate upgrades. Updates can be made to the BIOS, firmware, and patches to any of the Kaminario K2 components while the system is online.

Kaminario also supports a single management service across all storage elements in a K2 storage system.

Snapshot analysis

Today's virtualized and distributed workloads can strain the storage system. Flash-based storage, such as Kaminario's K2, has been meeting the challenge of resiliency, I/O performance, latency and throughput these workloads impose. Kaminario's K2 family of storage systems has been addressing customer requirements for quite some time and has pushed the boundaries of scalability and performance with each new generation of products.

The Kaminario K2 v4 offers another step forward and increases Kaminario's capability to support high levels of scalability and performance in mixed workloads while keeping the budget in mind.

Kaminario, however, faces a very competitive environment. Many other storage suppliers are using flash storage and storage virtualization technology to address the very same requirements. Dell, EMC, HDS, IBM, NetApp, Sanboloic, and several others are trying to win over the same customer accounts.

Can Kaminiaro win against larger and better funded competitors? The technology the company is offering can win if potential customers take the time to evaluate what it can do for them.
