Figure 1. Lenovo DSS-G Model G260

Lenovo Distributed Storage Solution for IBM Spectrum Scale (DSS-G) is a software-defined storage (SDS) solution for dense scalable file and object storage suitable for high-performance and data-intensive environments. Enterprises or organizations running HPC, Big Data or cloud workloads will benefit the most from the DSS-G implementation.

DSS-G combines the performance of the Lenovo ThinkSystem SR650 servers, Lenovo D1224 and D3284 storage enclosures, and industry leading IBM Spectrum Scale software to offer a high performance, scalable building block approach to modern storage needs.

Lenovo DSS-G is delivered as a pre-integrated, easy-to-deploy rack-level engineered solution that dramatically reduces time-to-value and total cost of ownership (TCO). All DSS-G base offerings described in this product guide are built on Lenovo ThinkSystem SR650 servers, Lenovo Storage D1224 Drive Enclosures with high-performance 2.5-inch SAS solid-state drives, and Lenovo Storage D3284 High-Density Drive Enclosures with large capacity 3.5-inch NL SAS HDDs.

Combined with IBM Spectrum Scale (formerly IBM General Parallel File System, GPFS), an industry leader in high-performance clustered file system, you have an ideal solution for the ultimate file and object storage solution for HPC and Big Data.

Did you know?

The DSS-G solution gives you the choice of shipping fully integrated into the Lenovo 1410 rack cabinet, or with the Lenovo Client Site Integration Kit, 7X74, which allows you to have Lenovo install the solution in a rack of your own choosing. In either case, the solution is tested, configured, and ready to be plugged in and turned on; it is designed to integrate into an existing infrastructure effortlessly, to dramatically accelerate time to value and reduce infrastructure maintenance costs.

Lenovo DSS-G is licensed by the number of drives installed, rather than the number of processor cores or the number of connected clients, so there are no added licenses for other servers or clients that mount and work with the file system.

Lenovo provides a single point of entry for supporting the entire DSS-G solution, including the IBM Spectrum Scale software, for quicker problem determination and minimized downtime.

IBM Spectrum Scale features

IBM Spectrum Scale, the follow-on to IBM GPFS, is a high-performance solution for managing data at scale with the distinctive ability to perform archive and analytics in place.

IBM Spectrum Scale has the following features:

  • Uses Declustered RAID, where data and parity information as well as Spare Capacity is distributed across all disks
  • Rebuilds with Declustered RAID are faster:
    • Traditional RAID would have one LUN fully busy resulting in slow rebuild and high impact overall
    • Declustered RAID rebuild activity spreads the load across many disks resulting in faster rebuild and less disruption to user programs
    • Declustered RAID minimizes critical data exposed to data loss in case of a second failure.
  • 2-fault / 3-fault tolerance and mirroring: 2- or 3-fault-tolerant Reed-Solomon parity encoding as well as 3- or 4-way mirroring provides data integrity, reliability and flexibility
  • End-to-end checksum:
    • Helps detect and correct off-track I/O and dropped writes
    • Disk surface to GPFS user/client provides information to help detect and correct write or I/O errors
  • Disk hospital - asynchronous, global error diagnosis:
    • If there is a media error, information provided helps in verifying and restoring a media error.
    • If there is a path problem, information can be used to attempt alternate paths.
    • Disk tracking information helps track disk service times, which is useful in finding slow disks so they can be replaced.
  • Multipathing: Performed automatically by Spectrum Scale, so no multipath driver is needed.
  • Supports a variety of file I/O protocols:
    • POSIX, GPFS, NFS v4.0, SMB v3.0
    • Big data and analytics: Hadoop MapReduce
    • Cloud: OpenStack Cinder (block), OpenStack Swift (object), S3 (object)
  • Supports cloud object storage:
    • IBM Cloud Storage System (Cleversafe)
    • Amazon S3
    • IBM SoftLayer Native Object
    • OpenStack Swift
    • Amazon S3 compatible providers

For details about these adapters, see the following product guides:

The transceivers and optical cables, or the DAC cables needed to connect the adapters to the customer-supplied network switches can be configured together with the system in x-config. Consult the product guides for the adapters for details.

Cluster network

The Lenovo DSS-G offering connects as a storage block to the customer's Spectrum Scale cluster network using the high-speed network adapters installed in the servers. Each pair of servers has two or three network adapters, which are either Ethernet, InfiniBand or Omni-Fabric Architecture (OPA). Each DSS-G storage block connects to the cluster network.

In concert with the cluster network is the xCAT management network. In lieu of a customer-supplied management network, the Lenovo DSS-G offering includes a ThinkSystem SR630 server running xCAT and a RackSwitch G7028 24-port Gigabit Ethernet switch.

These components are shown in the following figure.

Power distribution

Power distribution units (PDUs) are used to distribute power from an uninterruptible power supply (UPS) or utility power to the equipment within the DSS-G rack cabinet and to provide fault-tolerant power redundancy for high availability.

Four PDUs are selected for each DSS-G configuration (except for the G201 and G210 configuration which uses two PDUs). The PDUs can be one of the PDUs listed in the following table.

Table 13. PDU selection
Part number Feature code Description Quantity
46M4002 5896 1U 9 C19/3 C13 Switched and Monitored DPI PDU 4*
71762NX N/A 1U Ultra Density Enterprise C19/C13 PDU 4*

* DSS G100, G201 and G210 require only two PDUs

Each server, switch and drive enclosure has two redundant power supplies, and each of two power supplies is connected to a separate PDU to support topologies with redundant AC power sources.

As an example, the power distribution topology for the G204 (two servers, four drive enclosures) is illustrated in the following figure. Note that the actually PDU connections may vary in the shipped configuration.

Figure 8. Power distribution topology

Configuration notes:

  • Only one type of PDUs is supported in the DSS-G rack cabinet; different PDU types cannot be mixed within the rack.
  • Power cables lengths are derived based on the configuration selected.
  • PDUs have detachable power cords (line cords) and are country dependent.

IBM Spectrum Scale licensing

IBM Spectrum Scale licensing part numbers are listed in the following table. Licenses for DSS-G are based on the number and type of drives in the configuration and are offered in differing periods of support.

The core offerings available are:

  • For configurations with HDDs:
    • IBM Spectrum Scale for DSS Data Management Edition for Disk per Disk Drive
    • IBM Spectrum Scale for DSS Standard Edition for Disk Per Disk Drive

    Tip: The two mandatory SSDs needed for HDD configurations are not counted in the licensing.

  • For configurations with SSDs:
    • IBM Spectrum Scale for DSS Data Management Edition for Flash per Disk Drive
    • IBM Spectrum Scale for DSS Standard Edition for Flash per Disk Drive

Each of these is offered in 1, 3, 4 and 5-year support periods.

The number of licenses needed is based on the total number of HDDs and SSDs in the drive enclosures (excluding the logtip SSDs) and will be derived by the x-config configurator. The total number of Spectrum Scale licenses needed will be split between the two DSS-G servers. Half will appear on one server and half will appear on the other server.

Additional licensing information:

  • No additional licenses (for example, client or server) are needed for Spectrum Scale for DSS. Only licenses based on the number of drives (non-logtip) are needed.

  • For non-DSS storage in the same Cluster (for example, separated metadata on traditional controller-based storage), you have the option of socket-based licenses (Standard Edition only) or capacity-based (per TB) licenses (Data Management Edition only).

  • It is possible to mix traditional GPFS/Spectrum Scale storage licensed per socket and new Spectrum Scale storage licensed per drive, however the drive-based license is only available with DSS-G. As long as a Spectrum Scale client accesses storage that is licensed per socket (either cross-cluster/remote or locally), it will also require a socket based client/server license.

  • It is not supported to mix Standard Edition and Data Management Edition licensing within a cluster.

  • Drive-based Spectrum Scale for DSS licenses are not transferrable from one DSS-G configuration to another. The license is attached to the storage/machine it is sold with.

Installation services

Three days of Lenovo Professional Services are included by default with the DSS-G solutions to get customers up and running quickly. This selection can be removed if so desired.

Services are tailored to the customer need and typically include:

  • Conduct a preparation and planning call
  • Configure xCAT on the SR630 quorum/management server
  • Verify, and update if needed, firmware and software versions to implement the DSS-G
  • Configure the network settings specific to the customer environment for
    • XClarity Controller (XCC) service processors on the SR650 and SR630 servers
