 dual ported  2.5 inch NVMe PCIe SSD from OCZ

Z-Drive 6000 (html / pdf)
OCZ's 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 September. We had already heard before these new models include 2.5" hot swappable versions.

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).

R/W performance is upto 2.9GB/s and 1.4GB/s respectively. Random R/W IOPS are 700K IOPS and 120K IOPS. Latencies are 30s (write) and 80s (read). Endurance options are 1 or 3 DWPD.

high 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 conferences.

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 arrays.

Power consumption and heat in these NVMe SSDs?

I 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.

Hi 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 ecosystems

3. - An innovative 'flow-through' case design enables more airflow to critical components, keeping the device cool while reducing airflow requirements

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 Z-Drive 6000
  • Serviceability:- Hot-swap support enables serviceability without system downtime
  • 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 stored
  • 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 news archive

Editor:- September 9, 2014 - OCZ announced it is sampling a new 2.5" hot 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 availability of version 1.5 of its ZD-XL SQL Accelerator (PCIe SSD and caching software bundle) the beta version of which was announced in April. Internal 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 IOPS (4KB) in a FHHL form factor and is integrated with Windows WXL acceleration software.
