the big SSD memory architecture ideas in 2016?
and 4 companies which made me stop and think
|Editor:- December 30, 2016 - If you've been
having difficulty finding a common thread which links together all the
new technology developments which we have been reading about in 2016 and
which will dominate most of the SSD and memory developments in 2017 then
you're not alone. |
But I think I've found it. And it's at the heart of
my new home page blog on StorageSearch.com.
the new article
|"While NVMe over PCIe
shaves off about 10 microseconds relative to SAS, NVMf can shave off about 100
microseconds from the roundtrip latency between two hosts relative to protocols
such as iSCSI. It also saves CPU usage from TCP/IP processing. |
can be particularly beneficial in scale-out systems for transferring data
between hosts. It does require RDMA-capable NICs and DCB-capable switches, so it
will take some time for mass adoption."

Editor's comments:- this is what I said here in
SSD news - August
"Much less easy to place within any particular
calendar year and to rate for its significance to future SSD history - however -
due to its distinctly vaporware-like aspects and stunning lack of technical
details - was the stage managed unveiling of a newly branded memory architecture
by Intel and Micron - which (like the emperor's new clothes) may or may not
become significant for enterprise applications in 2016, or 2017 or 2018 -
depending on when we can see it working and depending on what other competitors
are doing at that time."

DSSD update from the gravity well of Dell EMC by the Register
December 15, 2016 - Despite having written about more than
500 acquisitions of
storage companies before the
modern era of SSDs
I always find it interesting to see what happens to SSD companies after
they get acquired
(my curiosity being understandable because over half the acquisitions which
have ever occured in
also involved active customers of mine at the time).
acquisitions we see a variety of outcomes:- some headline product lines get
retained, others get EOLed.
And sometimes it's not clear to see what happened because it can be years before
the technology and patents re-emerge in future products rather than
continuing as a single product strand.
A recent blog -

The Register includes this
observation about the DSSD product line which was acquired by EMC in
says - "We have been told that there have been around a dozen DSSD sales
totalling less than $6 million. Dell EMC has spent about $1.3 billion on DSSD,
with $1 billion in the acquisition in May 2014, and there are more than 200 DSSD
employees. We understand that Dell EMC may need to decide in the next six
months whether to keep investing for growth in DSSD or to decide to view it as a
niche product and resize the DSSD team to fit that niche dimensions." ...read

Tiering: the Future of Hyper Converged - by Adam Zagorski,
Marketing at Enmotus
- discusses how hyper-converged infrastructure has evolved along with the
associated impacts from data path latency and CPU overhead. Among other things
Adam notes that...
soon we'll have HCI clusters with several tiers of storage. In-memory databases,
NVDIMM memory extensions and NVRamdisks, primary NVMe ultrafast SSD storage and
secondary bulk storage (initially HDD but giving way beginning in 2017 to SSDs)
will all be shareable across nodes. Auto-tiering needs a good auto-tiering
approach to be efficient, or else the overhead will eat up performance."

Technologist, Evangelist - IBM in his new blog -

Among other things Woody says -
"There is no storage protocol inside the IBM FlashSystem 900. Once the
data hits the interface controller it ceases to be SCSI or PCI or NVMe. The
only thing better than an improved protocol like NVMe, is no protocol. The
FlashSystem 900, like many prior generations of FlashSystem solutions treats the
flash inside the system like memory. The result is unmatched latency
Latency was the central theme of Woody's
SSD bookmarks for
StorageSearch.com readers earlier this year too.
Woody has been
extolling the virtues of low latency enterprise SSD storage to me and my
readers for over 15 years.
I always relax when reading Woody's
writings about solid state storage as I can be secure in the knowledge that
everything he says is reliable.

Fujitsu says in-memory dedupe before writes to flash can double
best write speed
December 5, 2016 - Fujitsu
the development of a high-speed in-memory data deduplication technology for
use in all-flash arrays. The method decides if there is enough time to
search for duplicates in the flash array while retaining the data in cache
(low load condition). If so then writes to the flash array are only performed
after dedupe. Fujitsu says that for some workloads where there are many
duplications such as virtual desktops this can improve the user experience.
