Kaminario K2 All-flash Array
Storage for the All-Flash Data Center
Kaminario’s K2 all-flash array leverages a unique software-defined architecture that delivers predictable performance, scalability and cost-efficiency—highly valued predictability for the unpredictable world of the modern datacenter.
The Next Generation of All-Flash Array Technology is Here
The K2 All-flash array is the backbone of the modern data center. Uniquely equipped to scale easily and cost-effectively in mixed workload environments, the K2 is the first and only platform to deliver on the simplicity and agility of the all-flash vision.
Scale-out Performance Storage Architecture
Kaminario SPEAR combines Dell™ PowerEdge™ blade servers, Kaminario K2 solid-state storage area network (SAN) and SPEAR Storage OS to create a fast, highly available and easy-to-deploy distributed storage grid appliance. SPEAR also supports Kaminario DataProtect™ storage services, which enables the K2 storage to provide end-to-end high availability and fast, high-volume data protection to solid-state drive (SSD) storage, while delivering extreme performance.
The Kaminario K2 SAN solid-state hardware is based on PowerEdge blade servers and comes with a rack and enclosure to hold the following hardware components:
Blade servers — for managing data and storing digital RAM (DRAM) and/or Flash SSDs for primary storage and hard disk drives (HDDs) or Flash SSDs for data backup and redundancySwitches — for exposing Fibre Channel (FC) ports to multiple external hosts using FC switch, sending host data between blades using 10 Gigabit Ethernet (GbE) switch and supporting management communications between blades using one GbE switch Uninterrupted Power Supplies (UPS) — for delivering continuous power using two power supplies
SPEAR OS manages the following SPEAR components:
- ioDirectors — load balances the data to optimize K2 system resources utilization and scalability
- DataNodes — stores data in Flash or DRAM SSD and mirrors data for redundancy and data protection
SPEAR Storage OS has the following capabilities:
- Automated Data Distribution™ — senses the capacity available in the I/O and storage tiers automatically to balance data distribution for consistent high performance and low latency
- Intelligent Parallel I/O Processing™ — enables parallel I/O processing over multiple nodes to shorten the average response time of I/O requests
- DataProtect™ — enables K2 to provide data protection to SSD storage while delivering extreme performance
Storage Without Compromise

Optimized RAID protection, high availability design, and native replication deliver enterprise class resiliency.
Scale-out architecture and patented I/O optimization algorithms deliver consistently high performance in complex workload environments.
Designed for Scalability
Scale capacity and performance independently based on application needs. Add newest hardware to existing arrays with PerpetualArrayTM.
Manage Mixed Workloads
Deploy as a general purpose storage solution. Manage multiple workloads from a centrally managed storage platform.
Ultimate Cost Efficiency
Take maximum advantage of commoditization of flash to deliver enterprise class AFA at average price under $1/GB.
Leveraging the Economics of Flash Media
Flash media has benefited from step changes in cost efficiency. With benefit of Moore’s Law and the introduction of 3D TLC, the economics of flash keep getting better. K2 is architected to rapidly support the newest, densest flash. Perpetual Array enables customers to integrated the newest hardware in existing implementations.
The central principles of K2 management are simple. Administered via an intuitive browser-based GUI, K2’s built-in intelligence automatically executes RAID optimization, performance tuning, data distribution, monitoring, and capacity management. K2 supports a fully scriptable CLI, RESTful APIs, VMware vCenter plug-in and Microsoft VSS.
Non-disruptive Upgrade (NDU)
Hardware expansions and software enhancements can be deployed with no interference to production and no dependencies on maintenance windows. Upgrades can incorporate any preferred mix of controllers and SSDs, including newly released processors and drive types.
Maximize storage utilization using thin provisioning to assist long-term capacity planning. All base volumes, snapshots and replicas are thin provisioned, reducing required initial capacity and allowing measured, as-needed growth.
K2’s patented native writeable thin-provisioned and space-efficient snapshots deliver concurrent storage efficiency, performance, and scalability. With substantial capacity savings compared to full clones, snapshots are often used to create additional data sets for backup, archiving, development and testing.
Always-on K2 encryption provides protection against data theft, securing data-at-rest with no performance impact. 256-bit AES keys SSD encryption protects all data in the array with no impact on performance.
The Kaminario K2 is designed to meet the most demanding enterprise application requirements. HealthShield’s continuous call-home monitoring protection and analysis are the foundations for Kaminario world-class technical support. Proactive monitoring actively discovers and tracks events in real time, with many issues resolved remotely.
Predictability for the Unpredictable World
In the data center, predictable doesn’t mean boring. Storage infrastructure needs to evolve at the rate your business does. Learn how Kaminario is addressing the needs of the modern enterprise data center.
The K2 was designed from the ground up to scale easily and cost-effectively. Customers scale non-disruptively according to their specific capacity and performance needs. Managing mixed workloads from a single implementation delivers superior economics and simplified management.
The combination of scaling-out and the ability to provide consistent performance in mixed workload environments means the K2 supports a consistently high user experience, even as businesses scale, usage patterns change, and new applications are brought online.
The combination of K2 scale-up-and-out architecture with PerpetualArrayTM and its best-in-class capacity efficiency, means Kaminario can deliver highly predictable pricing on a dollar per effective capacity basis. This lets customers more effectively plan and manage expenses as they grow their business.
Kaminario and our K2 All-Flash Array Platform are both engineered for simplicity. Simple to work with. Simple to evaluate. Simple to implement. Simple to manage. Simple to grow. Simple to appreciate.
Kaminario Storage Innovation
Innovating All-Flash Enterprise Storage

Storage solutions that grow up, out, and forward just like your business. 5th generation plaform with unique set of technology benefits enabled by years of R&D and 20+ patents.
Agile Storage Infrastructure
The K2 is uniquely capable of scaling up and scaling out. Cost effectively add capacity by adding additional drive shelves to a pair of controller nodes. Deliver higher performance within a shared pool of storage volumes by scaling out. Independently optimize for both performance and cost efficiency according to the needs of your business.
The K2 scales-up to cost-effectively add capacity to a pair of controller nodes. And, the K2 scales-out to deliver higher performance within a shared pool of storage volumes.
By enabling both scale-up and scale-out, customers can optimize for both performance and cost efficiency for their specific application.
