2014-03 SATA Express & NVM Express Print
March 2014

This note focuses on two new related standards called SATA Express and Non-Volatile Memory Express (NVMe) respectively for SSD on PCIe.  This note is a bit forward looking and needs real life verifications over time.

Traditional Approach for SSD Connection: In a desktop situation, SATA ports are supported by the South Bridge (noting that the North Bridge has been absorbed into the CPU these days).  Some PCI Express slots are also supported by the South Bridge although they are mostly on Generation 2 (noting that some CPU provides Generation 3 support).  We may say that SATA ports and PCIe v2 slots are on the same level on the access hierarchy.  SSD with SATA interface and SSD with PCIe interface have been developed separately.

SATA Express

o SAS is going from version 2 at 6Gbps to version 3 at 12Gbps in 2014.  Traditionally SATA piggybacked on SAS.  For example, SATA3 ~ SAS2 = 6Gbps.  We may expect SATA to move to version 4 in 2014 but this is not happening.  SATA is moving to version 3.2 instead with SATA Express as a subset.

o The intention of creating SATA Express is to relate SATA to PCI Express in order for SSD to take advantage of the higher bandwidth of PCI Express.  PCI Express supports aggregations of up to 16 lanes.  We can see below that 2 lanes of PCIe v3 give 20Gbps which is higher than offered by SAS3 (or SATA4 if it exists).

SATA3       6Gbps
PCIev2 x1  5Gbps

SAS3         12Gbps
PCIev3 x1  10Gbps

o SATA Express provides 2 options of connections of SSD- one SSD for 2 lanes of PCI Express or 2 SSD on SATA3.  The PCI option provides the headroom for SSD to perform up to 20Gbps of disk read and write operations. 
SATA EXPRESS

NVMe (Non-Volatile Memory Express)

o Some SSD vendors have been ambitious in breaking the SAS2 limit by aggregating multiple SSD onto a PCIe card.  A read rate of 3GB/s has been published for products with an interface of PCIe v2x8.  Developments have been in different directions until NVM Express is agreed on as an industry standard for SSD on PCIe.  (Ref: 1B = 8b or 10b depending on the encoding scheme)

o SATA3 SSD supports a single command queue with up to 32 commands while NVMe supports up to 64K queues and 64K commands per queue. 

o Windows 8.1 and Server 2012R2 have native support of NVMe.  Linux 3.3 has included NVMe driver support from Intel.

o Whilst SATA Express limits a SSD to have an interface of 2 PCIe lanes, NVMe does not. 

o Sandforce announced in 2014-01 the release of SF3700 SSD controller that is compliant with NVMe for PCIe version 2 interface as well as SATA3.

3U12 Workgroup Server Print
March 2014
The Compucon 3U8 Workgroup server was first introduced in June 2011. The proposition was a 3U system offering 8 x System Nodes, with each node powered by an Intel Xeon E3-1200 processor, up to 32GB UDIMM ECC memory, a PCI-E x8 low profile expansion slot, 2 x 3.5" HDD, Dual GbE and dedicated IPMI remote management. In effect this provided 8 independent single socket Xeon systems in the space of a 3U rack mount chassis, thus offering excellent total cost of ownership. This month (February 2014) brings an update to our range of solutions, with additional variations to suit different needs.

All of the solutions presented (whether 8, 12 or 24 nodes) are conveniently integrated in a 3U rack mount chassis. They all support the latest generation of Intel Xeon E3-1200 V3 processors and up to 32GB of ECC memory. Other standard features are Dual GbE, dedicated LAN for IPMI remote management, heavy duty and optimised cooling, and platinum-level efficient and redundant power supplies.
3U12
The 3U12 solution offers 12 independent system nodes. For storage each system node supports up to internal 2 x 3.5" or 4 x 2.5" SATA HDD in RAID 0, 1 or 10. For networking each node can have InfiniBand FDR or 10GbE SFP+ instead of the standard Dual GBE.
3U24
The 3U24 solution offers 24 system nodes. The main advantage to this variation is the housing of 24 system nodes in the space of a 3U chassis. This is achieved by having 12 sleds that are hot-pluggable into the 3U chassis, with each sled offering two system nodes. The main disadvantage is in the lack of 10GbE or Infiniband networking options while storage-wise we can fit up to 2 slim 2.5" SATA SSD per system node (4 per sled).
3U8
The 3U8 solution offers 8 independent system nodes. By giving up processor density the main advantage of this arrangement is expandability and storage. Each of the 8 system nodes gain a low-profile PCI-E 3.0 x8 expansion slot in addition to a Micro-LP slot that provides Dual GbE, 10GbE, Dual-port 10GbE, or InfiniBand FDR options. Storage-wise, each system node takes up to 2 x front hot-swappable 3.5" SAS/SATA HDDs in RAID 0 or 1.

We recommend Fitness for Purpose and Total Cost of Ownership as the criteria for purchasing decisions.

Compucon CPD Seminar
12 March 2014 Wednesday
Compucon House Albany

4:00 – 4:15pm Outside the Square: Pick a stone in Space
4:15 – 5:00pm Review of IPVS, Video Analytics and Computer Vision
5:00 – 5:30pm What has happened in 2013 and what is new in 2014?
5:30 – 6:00pm Why should Compucon Peers do IPVS at all?
6:00 - 7:30pm Wine and Cheese

This seminar is open to business end-users but we expect it to be equally valuable to Compucon business peers. Free of charge.  Registration essential.

CCTV for closed circuit television is a well understood term but IPVS for Internet Protocol Video Surveillance is not.  A Google search on IPVS may produce mixed or confusing answers as the term was not universally or uniquely defined.  IP sounds modern and Video Surveillance is really the essence as it is what customers want to have.  To be blunt, there is nothing special about cameras that are seen to be the focus point of any CCTV or IPVS system.  A high resolution camera is almost a standard feature of a smart phone, tablet, or laptop.  As products become mature and commoditised, improvements in video surveillance come from how we put everything together to serve the specific requirements of customers. 

Video Analytics means analysing images captured by cameras in either real time or afterwards for useful information.  Motion detection is a simple real time application of video analytics.  Raising an alert when a person was caught falling down is another example.  Computer Vision is a more generic term and it encompasses IPVS, Video Analytics, and control actions.  Airplanes are capable of landing on an airport runway without a human pilot whether we trust it or not.  It is Computer Vision in action.  Human depends on eyes and light to see, but computer can do better without cameras and light.  Computer vision is therefore very powerful.  For example, the ultra-powerful telescope called SKA to be built in 2019 will help us find ET, dark matter, dark energy, and a lot of things beyond human vision.

It is nice to hear about big visions and big stories.  However, we will stay on the ground and review what has happened in 2013 that is of relevance to us in a daily practical sense.  Compucon has implemented 2 new IPVS projects in 2013, and provided regular system health monitoring service to 2 sites- one built in 2008 and one built in 2013.  We have practically tested more than 10 software applications for detecting human falls, traffic counts, objects disappearing (such as in museum) or appearing (such as a time bomb on the street).  We have touched base with our camera technology provider and obtained updates of their improved product features.  We plan to provide a summary of the above, and perhaps our experience of remote system health monitoring is the most impressive of all.

Why should Compucon peers be involved in IPVS as an IT operation?  Compucon is a computing technology company, and the link with computer vision is not unusual.  Compucon is a New Zealand member of the design team for the biggest instrument in the world.  Compucon has also done video surveillance systems in the country.  Compucon has been mentoring university students in computer vision among other technologies since 2000.  The common factor is computing technology.  Compucon has been supported by a peer group of consultants and service providers over the last 22 years, and this is part of the equation.  We will explain the lot in the seminar.

Pop in a coin, take control of an arm, and pick a toy of your favourite in the glass box.  Chances were 9.5 failures out of 10 attempts.  Many of us would have done that when we were not-too-small kids.   This type of fortune trying vending machines is still seen today in entertainment centres.  The idea has now been deployed to picking a stone in Space.  It is not one dollar a pop.  Fly an aircraft to space, align the flight path with an asteroid, capture the asteroid in a bag, and bring it back.  This is a genuine story to be told in this seminar.
