What is NonStop on x86?

January 12, 2015 4

NonStop moves to x86-64 and InfiniBand

• It uses an Intel x86 Xeon microprocessor running in 64b mode

– Through compiler and OS support it also runs in Big Endian from the user’s perspective

• It uses InfiniBand as the system fabric replacing ServerNet

– An increase in raw bandwidth from ServerNet 3 at 2Gb/s to InfiniBand FDR at 56Gb/s

• 10Gb Ethernet (which can be connected to 1Gb networks)

• The L15.02 release runs a fixed 4-core mode (L15.08 adds more options, more later)

• Up to 50% more performance capacity than an NB56000c (Poulson) for Order Entry on a per CPU basis

Terminology and Names

• The NonStop x86 based product line is called HP Integrity NonStop X

• The software release is called the L-Series and uses a new naming scheme (described later)

• The system architecture is called TNS/X (Itanium was TNS/E)

• The Processor Type is 11 (Itanium was 10 for all models)

• The short form Processor Name is NSX-D (model number 3), all models will be of the form NSX-xx

– As with Itanium, a given model may run with different IPU (aka cores) counts

• The first model in the NonStop X range is the NS7 X1

New system interconnect for NonStop X Industry-standard InfiniBand

• Shares many of the same features as ServerNet, including:

– Remote Direct Memory Access (RDMA)

– Guaranteed packet delivery

– Fault tolerance

– Scalability

• Increases the NonStop X system interconnect capacity by more than 25 times

• Improves packet latency (significant reduction)

• Delivers higher per port bandwidth to CLIMs

• Increases maximum CLIM connectivity

• Supports storage, IP, and Telco CLIMS

What is the same on Itanium and J-series?

• The system is c7000 chassis based

• The general system architecture is the same as J-Series

The collection of cores on a single blade compose a NonStop CPU

• 32b addressing is handled as sign extended 64b addresses

• The system is Big Endian (see later slide on how)

Binary data can be shared between Itanium and x86 without byte swapping

• TNS programs still run on the platform

But there is a new translator


Each byte of data in memory has its own address. Big-endian systems store the most significant byte of a word in the smallest address and the least significant byte is stored in the largest address. Little-endian systems, in contrast, store the least significant byte in the smallest address.


What is different about NonStop on x86 vs. Itanium?

• Since the system is composed of half height blades an entire 16 processor system resides in a single c7000 chassis.

– There is no dual c7000 configuration, for large system I/O multiple external IB switches are used.

• The system supports a larger memory configuration: up to 192GB/CPU

• The system is InfiniBand clustered

– Each blade has an InfiniBand Mezzanine card

– The c7000 has a pair of InfiniBand switches in the rear bay

• Native programs must be recompiled with x86 targeted compilers

– But those tools have the same look and feel as their Itanium counterparts

• There is one message system, comm, and storage Interrupt Process per IPU

– This allows better scaling as the IPU and CPU counts grow

• The Maintenance Entity functionality which previously was hosted on the ServerNet switches is now hosted on a pair of storage CLIMs

• In the case of a dual CPU halt with CPUs 0 and 1, both are memory dumped to a storage CLIM so the AI is collected

– Dumps to CLIM are encrypted



Deploying existing applications on NonStop X NonStop has successfully transitioned to new processor technologies in the past

Tandem CISC

1976

MIPS RISC

1990

Intel® Itanium®

2005 2015

Intel® Xeon®

Applications moving to NonStop X will have the same options as they had with prior technology introductions

• Some code runs ‘as is’ on the new platform without any change

• Some code may need to be accelerated—adding a new x86 binary to the existing object file

• Native code will need to be recompiled—to run on the new platform

NonStop processor technology introductions


What is the performance improvement with x86 vs. Itanium (NB56000c)?

• The SQL/MP Order Entry benchmark is 1.5x on a per CPU basis (4-way CPUs)

• Latency

– About a 50% improvement for small messages

– For large messages about a 7x improvement

• Disk:

– SSD

• Random I/O are ~25% faster

• Sequential reads are also 25% fast

• Sequential writes are about the same

– HDDs

• Are about the same for random operation and sequential writes

• Sequential reads are almost 2x better (with the faster IB is an important player)



L15.08: what is next

January 12, 2015 12

Some important parts of NonStop on x86’s functionality is coming

• Native IB clustering, that is IB connectivity between separate NonStop on x86 nodes

– There is no ability to cluster NonStop on x86 and Itanium NonStop systems with each other – use Expand over IP

• Core Licensing

– L15.02 is 4-core only

– L15.08 supports 2, 4 and 6 core options on the same hardware as the initial release (there is no new HW in the release)

HP Confidential


And it has a new naming convention

Software Release version is L-series

• Format: Lyy-mm: yy last two digits of release year, mm month of release

• For example

• L14.09 was the customer Beta RVU name, i.e. September 2014 release

• L15.02 is the PRG release

• L15.08 is the following release (Cognac wave 1.5)

• TOSVERSION is L06 and will remain so for all L-series RVUs

• Just like the TOSVERSION for H-series was H06 and J-series was J06

• Note that the above is in the human readable form, the internal version is “V06”

• A function available on all H, J, and L-series releases that returns the release name is being externalized in the Guardian Procedure Calls Manual (since the release name can no longer be constructed using TOSVERSION)

• SUTVER_GET_()


Big Endian, how does it work? The x86 is little endian, right?

• The compilers byte swap data items before placing them into memory for program variables

• Does not apply to non-program variables such as return addresses pushed onto the memory stack

• The OS along with the debuggers make the view complete

• But if you just scroll through memory you can see a mix of Big and Little endian datums

• Allows for binary data to be exchanged between Itanium and x86 systems without any special handling

• In particular, messages sent via Expand between a NonStop x86 based system and a NonStop Itanium system require no extra handling.
