Latency is the Final Frontier
The world of data center technologies and particularly storage
is experiencing fundamental shifts, a few tremendously overhyped technologies,
and some transformative innovations that may not catch your attention
immediately. Most of us are skeptical about self-proclaimed "visionaries" and
their predictions - me included. Yet
what we're witnessing is so powerful that we'll likely look back to 2019 as a
pivotal year when data centers became vastly more efficient, scalable, and
readily managed.
Here's our
team's storage take on winners and also-rans for 2019:
1. Latency is the final frontier, which NVMe
can and will overcome in 2019.
IOPs
don't matter anymore, given a single off-the-shelf flash drive can deliver 4-5
million IOPs/drive. Latency for scale-out architectures has become the final storage
frontier: these same flash drives offer under 200 microseconds of latency but the
challenge is to deploy NVMe at scale while preserving those low-latency
characteristics. Expect this challenge to be solved in 2019.
2. IoT
applications will drive storage needs.
We have a long way to go for AI to
become what the marketing folks claim it is
- machines actually learning
things autonomously. Some claim IoT will need AI to make any sense of all the
data connected devices gather, but I think this is just another way of feeding
the AI hype. What IoT
needs is strong analytics capabilities - low-latency storage, powerful GPU's
and applications.
That said, there is no way to ignore IoT: billions of connected devices are
capturing unprecedented amounts of data that can give us valuable new insights.
This data needs to be stored and will define new storage requirements: new
levels of scale and predictable performance (latency!).
3. GPU computing will require scale-out tier-0
storage.
Whether it is for high-performance analytics,
or actual AI and machine learning, GPU's are very much on the rise. Deploying
GPU's at scale for analytics-based applications requires scale-out tier-0
storage to feed the processors with larger data sets, versus using local flash
only.
4. SDS will give integrators a leading role.
Integrators
will play an increasingly important role in bringing to market specialized
storage solutions for cutting edge applications like AI/ML, VR/AR, and other
fast-growing sectors. They have access to scalable, high-performance
software-defined solutions, a wide selection of HW components and top-notch
applications such as data analytics etc.
5. More
use cases for flash and NVMe.
Continuing the 2018 trend of NVMe becoming a
commodity, we expect enterprise NVMe and Enterprise SATA SSD to achieve price
parity on a Euro/GB basis in 2019. Further, while not crossing the mythical
Euro/GB cost line of spinning drives, advancements in density such as 128TB
SSDs vs. spinning 3.5" drives at 14-16TB force end-users to consider SSD not
just for performance, but also for scale-out use-cases. The advantages in
density, power (and hence cooling) and random access ability of these SSDs will
make people start to doubt the viability of spinning media vs. the convenience,
far greater speed access and reliability of solid state media.
6. NVMe over TCP/IP.
2019 is the year for NVMe over Fabrics via
TCP/IP. The combination of a rich server ecosystem with all sever vendors
offering NVMe platforms, and the ubiquitous nature of Ethernet and TCP/IP, will
lower the hurdles to trial and adoption - driving a revolution in next generation
SAN.
