HPE Parallel File System Storage: технические характеристики и документация

HPE Parallel File System Storage 

Are you frustrated with the architectural and economical limitations of your current high performance file storage?

HPE Parallel File System Storage is cost-effective, parallel storage for your high-performance simulation, AI and data analytics environments running on HPE Apollo systems and HPE ProLiant DL servers with HPE InfiniBand HDR/Ethernet 100/200 Gb adapters.

It combines two iconic industry brands that do not need any introduction - the leading parallel enterprise file system (IBM Spectrum Scale - formerly known as GPFS) and the world's most secure industry-standard servers (rack-optimized HPE ProLiant DL servers) into a high performance, cost-effective software-defined storage solution that ships fully integrated as an HPE product from the HPE factory. With unified support from HPE Services services for the full storage solution.

HPE Parallel File System Storage provide multiples of performance and namespace scalability, as compared to standard scale-out NAS storage, to increase the utilization of your compute nodes by removing I/O bottlenecks while enable cost savings through storage island consolidation in a unified, high performance namespace. 

It is ideal for all organizations that leverage clusters of HPE Apollo systems or HPE ProLiant DL servers for High Performance Computing (HPC), Artificial Intelligence (AI) and High Performance Data Analytics (HPDA) workloads and who are struggling with the performance, scalability, and economics of their current storage infrastructure for unstructured data.

Platform Information

HPE Parallel File System Storage provides the following three ways to build a file system

• All user data in the file system on fast NVMe SSD
• All user data in the file system on cost-effective HDD
• Fast NVMe storage pool and cost-effective HDD storage pool in the same file system/namespace with two models of storage nodes that are based on HPE ProLiant DL325 Gen10 Plus rack servers
• HPE Parallel File System 16 Flash Bays Server
• HPE Parallel File System 8 Disk Bays Server.
• HPE Parallel File System 12 Disk Bays Server
• HPE Parallel file System Base Protocol Server 

The above servers run the iconic IBM Spectrum Scale ® parallel file system in Erasure Code Edition (ECE). IBM Spectrum Scale ECE was designed to be deployed on standard rack servers like the HPE ProLiant DL325 Gen 10 Plus. ECE provides

all the functionality, reliability, scalability, and performance of IBM Spectrum Scale with the added benefit of network-dispersed IBM Spectrum Scale RAID, which provides the ability build IBM Spectrum Scale-based storage systems from clusters of cost-effective, high volume rack servers like the HPE ProLiant DL brand.

The Parallel File System Protocol Server provides a pre-configured server to address the need to give access to PFSS file systems to NFS, SMB and Object (S3) clients. This allows the customer to serve shared data to all major access platforms.  

For a detailed description of the functionalities of the IBM Spectrum Scale parallel file system please refer to the IBM Redbook IBM Spectrum Scale (formerly GPFS) as well as to the IBM Redbook IBM Spectrum Scale Erasure Code Edition - Planning and Implementation Guide. Both documents provide background information on the broad set of enterprise storage functionality of the embedded parallel file system but are not necessary to configure and order HPE Parallel File System storage. 

The intent of HPE Parallel File System Storage is to take the complexity out of planning and implementing IBM Spectrum Scale on cost-effective, high volume rack servers by

• Pre-configuring the two models of storage servers described below.
  Do not worry about component selection like processor type, core counts, memory configurations etc. The HPE team already has done this work for you for this high-performance storage use case.
• Pre-installing all the software required already in the HPE factory accelerating the deployment and simplifying the installation process. Even the install packages of the IBM Spectrum Scale clients for the compute nodes are also included on the two models for storage servers when they arrive in your location.
• Providing installation services through our global HPE Services Services organization 

This is expected to be a major value proposition for customers who are using or planning to use clusters of compute nodes composed of HPE Apollo systems of HPE ProLiant DL rack severs that are interconnected with low latency 200 gigabit per second networks for simulation, artificial intelligence, or high-performance data analytics workloads as they now: 

• Can have "one hand to shake" in the procurement process for the end-to-end (E2E) system - for both HPC/AI compute and HPC/AI storage
• Can have "on throat to choke" in the problem identification process for E2E issues - with HPE Services Services as the single point of accountability
• Have the option to consume the full E2E system with subscription-based, as-a-service models like HPE GreenLake

Features and Benefits

The performance your HPC/AI clusters need

HPE Parallel File System Storage is built on industry standard server technology utilizing the AMD EPYC 7000 series processor family and HPE Smart Memory up to 3200 MT/s DDR4 memory.

Fast PCIe 4.0/ NVMe SSDs are the standard medium to deliver performance with the ability to add HDD storage pools in the same namespace to provide cost-effective storage capacity.

High speed, low latency networks like InfiniBand EDR/HDR or 100/200 Gigabit Ethernet deliver the data to the CPU or GPU compute nodes without input/output (IO) bottlenecks.

NVIDIA Magnum IO support for accelerated input/output (IO) for NVIDIA GPUs which provides a path for data to bypass CPUs.

Highly available write caching (HAWC) leverages non-volatile storage in the compute nodes for accelerated IO for write-intensive applications, 

The scalability your HPC/AI clusters need

HPE Parallel File System Storage supports up to 128 storage servers in a single file system/name space - far beyond the limitations of NAS storage.

• Start with as little as four rack units to then go to wherever you need.
• Scale-out very granular in increments of one rack unit.
• Scale-out PCIe 4.0/ NVMe flash performance independently from cost effective HDD capacity in the same file system. 

Notes: The current limitation to 128 storage servers is a testing limit in the current version and not an architectural limit. 

The enterprise storage features you need

HPE Parallel File System Storage offers system availability features that provide enterprise-grade "Five nines" availability levels with automatic fail-over and intelligent fail-back for mission-critical use cases. 

Comprehensive set of data protection features like snapshots, synchronous and asynchronous replication, file-level encryption (in-flight and at-rest) and asynchronous error diagnosis while affected input/output (I/O) operations continue.

Supports interfaces for file (POSIX, NFS, CIFS), object (S3, SWIFT) and Hadoop Distributed File System (HDFS) for a broad data accessibility across the organization. 

The cost-effectiveness your HPC & AI budget needs

HPE Parallel File System Storage enables "storage islands" consolidation for your HPC, AI and HPDA environments.

Its software-defined architecture combines the leading enterprise parallel file system with the leading rack-optimized industry standard servers as storage nodes.

The end-to-end customer support you need

HPE Parallel File Systems storage ends the era when you needed to buy different vendors for the compute and the storage portion of your HPC & AI cluster to get "best-of-breed" on every layer of the technology stack. No more!

Now you can get "best-of-breed" on every layer with HPE Services services as the Single Point of Accountability (SPOA) for your end-to-end infrastructure for HPC, AI and HPDA workloads running on HPE Apollo systems or HPE ProLiant DL rack servers.

Erasure Code Edition Features

HPE Parallel File System Storage does not need external, highly available RAID controllers, because the RAID functions are handled by the embedded IBM Spectrum Scale ECE software. 

IBM Spectrum Scale ECE supports two and three fault tolerant RAID codes. The two-fault tolerant codes include 8 data plus 2 parity, 4 data plus 2 parity, and 3-way replication. The three-fault tolerant codes include 8 data plus 3 parity, 4 data plus 3 parity, and 4-way replication. Figure 1-3 shows example RAID tracks consisting of data and parity strips.

Figure 1-3: RAID tracks

IBM Spectrum Scale RAID

Distributes data and parity information across node failure domains to tolerate unavailability or failure of all storage drives in a node. It also distributes spare capacity across nodes to maximize parallelism in rebuild operations. IBM Spectrum Scale RAID implements end-to-end checksums and data versions to detect and correct the data integrity problems of traditional RAID.  

Erasure Code Edition (ECE) takes this to the next level by distributing the data across a set of share nothing nodes allowing for granular scale out with simplified node configurations (no more need for complicated and expensive dual node servers with shared disks/flash). Leverage the bidirectional nature of modern high-speed networks to minimize impact on the network performance.  

ECE keeps data integrity and version information with the data from the time the data leaves the client node to the time it is stored on disk. This enables higher data integrity checking than can be achieved by T10Dif alone.

Due to the overhead for data protection (RAID Level) the usable capacity of HPE Parallel File System storage is less than the raw capacity (capacity of all configured storage drives combined).

Hardware Features

The HPE FPSS leverage the outstanding capabilities of the HPE ProLiant server line to deliver high value in granular scalable configurations.  By taking advantage of the AMD Epyc line of processors and their high IO capabilities HPE delivers high performance without the high price tag.   

All nodes are configure with AMD epic processors with 8 to 48 cores depending on the configuration and 64GB to 128GB of 3200MTs.  This enables all the performance of the installed HDDs/SSDs to be exposed to the client systems. It also allows for plenty of head room for delivering advanced functions with virtually no impact to performance. 

In order to get the most out the storage high speed dual protocol NICs are used that can support both InfiniBand and Ethernet at either 100Gb or 200Gb speeds. 1 or 2 NICs can be configured to support a range of connectivity and availability requirements.  

A range of HDD and SDD choices are available to ensure capacity and performance requirements can be met precisely. No need to over provision capacity to meet performance requirements or visa versa.
