At Storage Field Day last month, Jon Klaus saw a presentation from SNIA, where they talked about tail latency. These are tiny spikes in latency, 2-10x longer than higher. These can have big impacts, effecting up to 2% of all IO, which is magnified when seen at a hyperscale level. Smaller organizations might simply over provision to lower overall latency so that these spikes still fall within acceptable ranges, but at scale this approach isn’t practical. SNIA presented several ways to overcome tail latency, and Jon shares his thoughts on what he saw.
Intel SPDK and NVMe-oF will accelerate NVMe adoption rates
Intel’s presentation from Storage Field Day this month certainly made an impression on the delegates. Jon Klaus wrote up his thoughts. He goes into particular details over SPDK and NVMe over Fabrics, both of which he thinks will have genuine business impacts for overall NVMe adoption. For Jon, this is an example of Intel pushing software to truly catch up to recent advances in hardware.
Storage Field Day 12: storage drop bears reunited!
Storage Field Day is coming up in March, and we’re excited to have Jon Klaus returning! He wrote up a great preview of some of the companies he’s excited to see. Jon found the presenting companies to be a good mix of returning ones he’s interesting in catching up with, and new ones that will be presenting new products and solutions. It should be a great event, so make sure to check out our comprehensive video coverage, both live and after SFD!
Building a hybrid cloud with Avere
Jon Klaus takes a look at what Avere is offering with their hybrid cloud solution. He has a long history with the company, going back to when they were focused on NAS optimization via a caching layer between storage and compute resources. Avere then moved into object storage translation, and is now entering into making cloud storage gateways. He gives some thoughts about what applications their gateway would benefit, weights in on caching vs tiering, and where he thinks these kind of products fit into IT. He doesn’t see the cloud ever killing the tangible benefits of on-prem, but hybrid solutions could certainly benefit both.
Hardware has set the pace for latency, time for software to catch up
Jon Klaus thinks software needs to catch up to SSDs for reducing application latency. Initially, SSDs were limited by storage processors and buses build with spinning disks in mind. This has largely been remedied, so where’s the next big performance bottleneck? Latency.
Jon looks at how Intel’s Storage Performance Development Kit, presented at Storage Field Day in October, effects latency by replacing the traditional Linux kernel in storage controllers.
