programmable power envelope 2.5" hot swap NVMe SSDs|
|Editor:- May 20, 2015 - OCZ today revealed more
details about the new models shipping in its NVMe compatible PCIe SSD family
- which was first announced last
had already heard before these new models include 2.5" hot swappable
Today OCZ said this model - the
Z-Drive 6300 SFF
will be available with usable capacities of 800GB, 1.6TB and 3.2TB (in
this quarter) followed by 6.4TB (later this year).
performance is upto 2.9GB/s and 1.4GB/s respectively. Random R/W
700K IOPS and 120K IOPS. Latencies are 30s (write) and 80s (read).
options are 1 or 3 DWPD.
availability and reliability features
The new Z-Drive 6000 models
are dual ported so that 2 host systems can concurrently access the same SSD.
Additionally, the Z-Drive 6000 Series supports hot swapping of 2.5"
drives, pre-set power thresholds and temperature throttling to support many
types of enterprise ecosystems.
Editor's comments:- for various reasons to do with a
combination of standardization
efforts and changes
of ownership for nearly every major enterprise PCIe SSD company in the
market - you've had to wait 3 years since the idea of this kind of product was
first discussed seriously on
these pages and at
What has become clear to systems architects is that these
new products offer far more flexibility in their roles than merely performance
upgrades to high end SAS
SSDs and traditional storage arrays.
Among other things these new
types of products will enable lower cost mini SSD server clustering at
PCIe latencies which will spur growth in the SDS market. At the high end - they
could become the new building blocks inside the world's most powerful computer
Power consumption and heat in these NVMe SSDs?
know from talking to systems architects that the electrical power and thermal
footprints of 2.5" NVMe SSDs is a critical detail when considering the
design of dense storage arrays so I asked Scott Harlin,
OCZ for more information these factors. Here's what Scott said.
Zsolt you are correct the 2.5" drives can get a little toasty packing in
the higher densities into this form factor -- typical power consumption of the
Z-Drive 6000 series is 25W active and 9W idle. So we included a few items to
address these concerns:
1. - Temperature sensing and thermal throttling to maintain
consistent operating conditions even under adverse temperature variances
2. - User-selectable power envelopes, in 15W, 20W and 25W
settings, reduces wasted power when maximum performance is not required while
efficiently addressing temperature requirements in support of a variety of
3. - An innovative 'flow-through' case design enables more
airflow to critical components, keeping the device cool while reducing airflow
Editor's comments:- that user selectable power envelope- in graduated
steps - seems like a really useful design attribute. So I'll be watching out
for it in future arrayable SSD launches.
| systems aspects of the
- Serviceability:- Hot-swap support enables serviceability without system
- Drivers:- Windows, Linux, UNIX, Solaris, VMware, UEFI
- Power Consumption:- Idle: 9.0W (typical), Active: 25W (typical)
- Data Path Integrity:- End-to-end data protection performs data integrity
checks at every juncture where data is transmitted, received, processed and
- Power Loss Protection:- completes in-flight write operations to prevent
data loss in the event of a sudden power failure
earlier mentions of OCZ 's PCIe SSDs
- from the
Editor:- September 9, 2014 -
it is sampling a new
swappable enterprise PCIe SSD - the Z-Drive 6000 - a native PCIe 3.0
NVMe 1.1 solution - which "provides industry-leading
IOPS per dollar".
Editor:- July 15, 2014 - OCZ this week announced
1.5 of its ZD-XL SQL Accelerator (PCIe SSD and caching software bundle) the
beta version of which was announced in
testing performed by OCZ delivered over one million TPMs for a sample of 50
virtual users when ZD-XL SQL Accelerator 1.5 was located in the same server as
the SQL application.
Editor:- March 4, 2014 - OCZ today launched - the
Z-Drive 4500 Series - which has upto 3.2TB of usable
19nm flash, R/W bandwidth
of 2.9GB/s and 2.2 GB/s respectively, and 252K / 76 K R/W
in a FHHL form factor and is integrated with Windows WXL acceleration
