[gpfsug-discuss] *NEWS* - IBM Spectrum Scale Erasure Code Edition v5.0.3

[Frank Kraemer]

FYI - What is IBM Spectrum Scale Erasure Code Edition, and why should I
consider it?

IBM Spectrum Scale Erasure Code Edition provides all the functionality,
reliability, scalability, and performance of IBM Spectrum Scale on the
customer’s own choice of commodity hardware with the added benefit of
network-dispersed IBM Spectrum Scale RAID, and all of its features
providing data protection, storage efficiency, and the ability to manage
storage in hyperscale environments. SAS, NL-SAS, and NVMe drives are
supported right now. IBM Spectrum Scale Erasure Code Edition supports 4
different erasure codes: 4+2P, 4+3P, 8+2P, and 8+3P in addition to 3 and 4
way replication. Choosing an erasure code involves considering several
factors.

IBM Spectrum Scale Erasure Code Edition more details see section 18 in the
Scale FAQ on the web
https://www.ibm.com/support/knowledgecenter/STXKQY/gpfsclustersfaq.html

Each IBM Spectrum Scale Erasure Code Edition recovery group can have 4 - 32
storage nodes, and there can be up to 128 storage nodes in an IBM Spectrum
Scale cluster using IBM Spectrum Scale Erasure Code Edition. For more
information, see Planning for erasure code selection in the IBM Spectrum
Scale Erasure Code Edition Knowledge Center.

Minimum requirements for IBM Spectrum Scale Erasure Code Edition see:
https://www.ibm.com/support/knowledgecenter/STXKQY_ECE_5.0.3/com.ibm.spectrum.scale.ece.v5r03.doc/b1lece_min_hwrequirements.htm


The hardware and network precheck tools can be downloaded from the
following links:
Hardware precheck: https://github.com/IBM/SpectrumScale_ECE_OS_READINESS
Network precheck: https://github.com/IBM/SpectrumScale_NETWORK_READINESS

The network can be either Ethernet or InfiniBand, and must be at least 25
Gbps bandwidth, with an average latency of 1.0 msec or less between any two
storage nodes.
