Redis Labs introduced help for Intel Optane DC persistent reminiscence in Redis Enterprise on Thursday. The pairing of the 2 makes good sense: Redis is a distributed in-memory key-value database, and Optane is positioned as a non-volatile RAM answer, aiming to make in-memory databases work at scale with out the technical danger of dropping knowledge inherent to the usage of risky RAM.
Redis Enterprise contains two utilization modes for Optane-powered programs. Reminiscence Mode prioritizes efficiency, and AppDirect mode prioritizes value financial savings. “Utilizing Reminiscence Mode, Redis Enterprise-powered functions can obtain comparable efficiency to DRAM with important value advantages. Builders can obtain even better value financial savings utilizing AppDirect mode with Redis Enterprise, whereas nonetheless delivering considerably quicker efficiency in comparison with NVMe,” the corporate said in a press launch.

Presently, Intel’s Optane RAM merchandise are solely obtainable as a part of a beta. As a result of variations between Optane DIMMs and normal DRAM DIMMs, the expertise is simply supported on newer Intel server platforms, beginning with Cascade Lake-AP.
Optane-also referred to as 3D XPoint-is quicker than NAND-based SSDs, although slower than conventional DRAM. It’s, nevertheless, considerably extra dense than DRAM, permitting Intel to cram 512GB in a single module. Database functions together with Redis stand to learn essentially the most from Optane DIMMs, as in-memory processing, or just storing bigger working units in reminiscence, enable for considerably quicker transaction speeds, as writes don’t should be instantly pushed via PCIe-linked solid-state storage, eliminating a major bottleneck.
Analysis into in-memory processing predates Optane, although decrease knowledge densities and inherent volatility of conventional DRAM have restricted business deployments. As Optane DIMMs retain the nonvolatile properties of strong state drives, it decreases the period of time required for a reboot.
Intel’s Optane storage merchandise for workstation programs have been additionally proven off at CES 2019, with the brand new Optane Reminiscence H10 using the storage expertise as a cache for QLC NAND flash reminiscence, utilized in typical SSDs, on a single M.2 2280 module.
The massive takeaways for tech leaders:
- Redis Enterprise contains two utilization modes for Optane-powered programs. Reminiscence Mode prioritizes efficiency, and AppDirect mode prioritizes value financial savings.
- Optane is quicker than NAND-based SSDs, although slower than conventional DRAM. It’s considerably extra dense than DRAM, with as much as 512GB in a single module.
