Hi I'm Micah Bhakti from Intel and in this video,
-
I'm going to share a bit about DAOS,
-
our software defined storage engine, designed specifically
-
around persistent memory.
-
I'll tell you a bit about how DAOS will benefit you
-
as a developer, and give you some resources
-
so that you can learn more.
-
DAOS, or our Distributed Asynchronous Object Storage
-
is a storage engine designed from the ground up to leverage
-
a combination of persistent storage class memory,
-
and traditional NVME SSDs.
-
Persistent memory, also known as storage class memory,
-
is a new hardware technology that provides byte addressable
-
storage like DRAM, but which retains data when powered off.
-
This is important because it allows us to build new storage
-
systems with much higher performance
-
than is possible with traditional disks.
-
One of the problems with adding persistent memory
-
into current storage systems is that conventional software
-
defined storage was designed around block addressable media
-
like SSDs and hard drives.
-
These types of devices have relatively high latency.
-
So a few extra microseconds for the software
-
stack to process the I/O is not noticeable.
-
With storage class memory however,
-
this extra software overhead prevents applications
-
from taking full advantage of the performance benefits.
-
DAOS was created from the ground up to address this problem,
-
and runs completely in userspace to minimize software overhead
-
while using standardized PMDK and SPDK libraries to write
-
to the underlying devices.
-
This allows us to maximize the IOPS and bandwidth
-
that applications can get from the storage class memory
-
hardware.
-
This means that if you want to implement an S3 interface, NFS,
-
or provide virtual block storage on top of the DAOS engine
-
you can do that, and as a developer,
-
you don't have to worry about how your data is being written
-
or persisted underneath.
-
Within the storage engine DAOS is automatically taking
-
care of the features, such as transactional non-blocking I/O,
-
advanced data protection with self-healing
-
on commodity hardware, end-to-end data integrity
-
checks, fine grained data control, and elastic storage
-
provisioning to optimize performance and cost.
-
DAOS is an open source project under the Apache 2.0 license
-
and it's freely and openly available from our GitHub
-
project.
-
I encourage you to contribute.
-
Intel is looking to create a vibrant community around DAOS,
-
so please download and try out the product as a user as well.
