Suppose you’re a game developer with a release coming up. If things go well, your user base could go from zero to hundreds of thousands in no time. And these gamers expect your app to capture and store their data, so the game always knows who's playing and their progress in the game, no matter where they log in. You’re implementing an underlying database to serve these needs.
|
|
|
|
|
|
Oh—and you’ve got to do that without adding costly DRAM to existing systems, and without much of a budget to build a brand-new large shared memory or distributed multi-node database solution. Don’t forget that you can’t let your performance get bogged down with IO latency from a traditionally attached flash storage array.
|
|
|
|
|
|
More and more, companies are choosing NoSQL over traditional relational databases. NoSQL offers simple data models, scalability, and exceptionally speedy access to in-memory data. Of particular interest to companies running complex workloads is NoSQL's high availability for key value stores (KVS) like [Redis](https://redislabs.com/solutions-redis-labs-on-power) and MemcacheDB, document stores such as mongoDB and couchDB, and column stores Cassandra and BigTable.

## Computing Challenge
|
|
|
|
|
|
NoSQL isn't headache-free.
|
|
|
|
|
|
Running NoSQL workloads fast enough to get actionable insights from them is expensive and complex. That requires your business either to invest heavily in a shared-memory system or to set up a multi-node networked solution that adds complexity and latency when accessing your valuable data.
|
|
|
|
|
|
Back to our game developer and their demanding gamers. As the world moves to the cloud, developers need to offer users rapid access to online content, often tagged with metadata. Metadata needs low response times as it is constantly being accessed by users. NoSQL provides flexibility for content-driven applications to not only provide fast access to data but also store diverse data sets. That makes our game developer an excellent candidate for using CAPI-attached Flash to power a NoSQL database.
|
|
|
|
|
|
## The Solution
|
|
|
|
|
|
Here's where CAPI comes in. Because CAPI allows you to attach devices with memory coherency at incredibly low latency, you can use CAPI to affix flash storage that functions more like extended block system memory for larger, faster NoSQL. Coming together, OpenPOWER Foundation technology innovators including [Redis Labs](https://redislabs.com/solutions-redis-labs-on-power), [Canonical](https://insights.ubuntu.com/2014/10/10/ubuntu-with-redis-labs-altera-and-ibm-power-supply-new-nosql-data-store-solution/), and [IBM](http://ibm.co/1FxOPq9) created this brilliant new deployment model, and they built [Data Engine for NoSQL](http://ibm.co/1FxOPq9)—one of the first commercially available CAPI solutions.

CAPI-attached flash enables great things. By CAPI-attaching a 56 TB flash storage array to the POWER8 CPU via an FPGA, the application gets direct access to a large flash array with reduced I/O latency and overhead compared to standard I/O-attached flash. End-users can:
|
|
|
|
|
|
- _Create a fast path to a vast store of memory_
|
|
|
- _Reduce latency by cutting the number of code instructions to retrieve data from 20,000 to as low as 2000, by eliminating I/O overhead[1](#_ftn1)_
|
|
|
- _Increase performance by increasing bandwidth by up to 5X on a per-thread basis[1](#_ftn1)_
|
|
|
- _Lower deployment costs by 3X through massive infrastructure consolidation[2](#_ftn2)_
|
|
|
- _Cut TCO with infrastructure consolidation by shrinking the number of nodes needed from 24 to 1[2](#_ftn2)_
