ClusterStor G300N Architectural Elements
|
ClusterStor G300N provides a pre-installed and pre-configured deployment of the Spectrum Scale file system, based on version 4.2.3 (or higher) designed to deliver sustained high performance throughput, with integrated high availability and resiliency features, end-to-end system management, and the ability to expand existing systems. Due to industry leading performance efficiency, ClusterStor uniquely offers these features with minimal use of energy consumption, cooling, and data center footprint. Truly scaling file system performance efficiently means aggressively reducing the space, power, cooling and time required to achieve HPC performance and results. Spectrum Scale is client/server based software that uses a distributed architecture and is designed for medium to large-scale compute and I/O-intensive, performance-sensitive applications. The G300N architecture is used for many different types and sizes of Linux and Windows clusters. G300N with Spectrum Scale is designed to meet the needs of data-intensive applications including content repositories, technical computing and big-data analysis. Each ClusterStor G300N system includes a base rack, containing a pair of redundant, top of rack (TOR) management switches providing high availability, out-of-band management of the ClusterStor solution. Each base rack also includes the System Management Unit (SMU), which is provided for G300N cluster management functions of the solution. Redundant high availability server node pairs with data protection storage in a 2U24 chassis is used to support management. | |
|
Spectrum Scale Network Shared Disk (NSD) Servers
|
The basic building block of ClusterStor is the Scalable Storage Unit, or SSU. The SSU is five rack units (5U) high and delivers up to 12GB/sec of sustained file system performance as verified by the IOR benchmark suite over EDR Infiniband, Intel Omni-Path or 40/100GbE high speed networks. The SSU contains two Spectrum Scale Network Shared Disk (NSD) Servers in a high availability (HA) configuration, utilizing high performance Intel processors. Each NSD controls one NSD, for a total of two NSDs per SSU using Seagate GridRAID with T10-PI type 2 formatted drives for data protection and integrity. The two NSDs are configured with Seagate GridRAID as 40 or 41 Drives per OST, using 8+2 Data plus Parity blocks, and 2 integrated sparing drives distributed as spare blocks within the GridRAID architecture, providing the fastest recovery possible for a failed hard drive. The ClusterStor G300N base rack may contain up to seven SSUs. | |

G300N Expansion Rack | |
|
The ClusterStor G300N further expands with the addition of expansion racks. Each expansion rack contains a pair of redundant, top of rack (TOR) management switches and up to seven SSUs. With the addition of each SSU (or addition of expansion rack(s) containing SSUs), the ClusterStor G300N increases performance and capacity. | ||

The ClusterStor architecture removes complexity and is naturally more efficient by design. The ClusterStor SSU integrates operating system, data protection, the Spectrum Scale file system and management into a single high availability building block that consolidates storage, network and server processing. The result is an easy to deploy, easy to use and easy to manage solution. There is no need to guess at how to scale; each SSU is a balanced performance building block delivering a predictable level of performance and storage capacity.
Overall system performance is directly proportional to the number of SSUs due to ClusterStor's efficient internal optimization that yields industry leading linear performance scalability. End users simply configure the ratio of SSUs and/or Expansion Storage Units (ESUs) to satisfy their performance and/or data capacity needs. See the Installation Guide for details on supported configurations including SSUs and attached ESUs.
ClusterStor G300N Scalable Storage Unit (SSU) The Scalable Storage Unit (SSU) in the ClusterStor G300N system is based on the Seagate designed, developed and manufactured industry leading enterprise 5U84 3.5 inch drive platform, featuring:

Embedded Server Modules (ESM) | |
|
The Seagate ClusterStor G300N SSU enclosure is pre-integrated into the Seagate provided rack and offers a high-density design, with no single point of failure. At the front of the enclosure there are two drawers, each containing 42 drive bays, supporting 3.5 inch dual-ported SAS drives housed within carriers, with redundant data paths from each server/controller module to each drive. Each drawer can be easily accessed from the front of the enclosure, eliminating the need to remove the SSU from the rack. Drives are hot-swappable, enabling the system to remain fully operational, within normal thermal specifications, for several minutes when a drive is replaced. The platform offers fully redundant power and cooling. The enclosure is designed to maximize the reliability of the hard disk drive (HDD), with vibration dampening and temperature monitoring technology throughout the system. The front panel includes an operator control panel located on the front bezel, which is used to indicate the shelf number where the enclosure is located in a rack, and the general health of the enclosure. The rear of the enclosure houses two Embedded Server Modules (ESMs), two power supplies and five cooling modules. The SSU minimizes energy use through advances in Seagate's advanced adaptive cooling technology and Platinum Certified PSUs that are 92% efficient at 50% load. Additionally, The SSU is designed to meet and exceed stringent worldwide requirements for recycling and environmental friendliness. | ||||
|
SSU Embedded Server Module (ESM)
|
The Embedded Server Module (ESM), also referred to as a storage application controller or Spectrum Scale NSD controller, is a dedicated x86 hardware server module that utilizes the Storage Bridge Bay (SBB) industry standard form factor, enabling it to plug directly into the Seagate (OneStor) family of enclosures. The ESM combines the attributes of a standard server, a RAID controller and a JBOD module into one modular design capable of running standard operating systems. Up to two ESMs can be installed in a single SSU enclosure to provide embedded server and storage application functions. | |||
|
Storage Management |
Graphical user interface for common administration tasks can speed provisioning, configuration and monitoring of an Spectrum Scale cluster. It enhances administrator productivity and simplifies new deployments. Also available is ClusterStor CLI (CSCLI), which includes a robust set of CLI commands enabling many system administration actions and functions. | |||
|
ClusterStor Serviceability
|
All systems logs are consolidated across the entire cluster into the central management server, this includes logs from every layer of the system from disk drive data through reporting information to G300N error messages. This enables administrators to easily identify anomalies in the ClusterStor operation and proactively service the system to avoid downtime/performance impacts. The hardware incorporates a modular design that enables commonly failing components to be field serviceable. The most commonly anticipated failure items are disk drives, controllers/server modules, power supplies and cooling modules, all of which can be easily serviced without downtime. SSU disk drives are located in a pull-out drawer and are released by the press of a button. LED indicators help service personnel identify the correct disk to be repaired. The maintenance operation to remove a failed disk drive and install a replacement drive in an SSU typically take no more than 2 minutes to complete. After a disk drive is replaced, the system uses a discovery process to identify the new drive and include this new hardware in the available storage inventory. HDD replacement on the SMU is identical to the SSU disk drive replacement procedure. The controllers themselves, identified as critical to the system are individually serviceable, with a failed module being easily replaced even while data is still being served and all NSDs being accessed thru its partner ESM | |||
