Orga file system

The Orga file system provides extensive data capacity (approximately 14 PB of storage overall) for high performance storing and accessing research data based on IBM Spectrum Scale (formerly known as GPFS).
Orga file system is made of different storage tiers to ensure the users will benefit of the maximum performance and it’s mounted on about 600 nodes.

Minerva storage components:

Metadata and Tier-1

  • Flash: stores all metadata for the file system - 264 TB (Available in Q1 2018)

Tier-2 (high-speed data storage)

  • DDN12K: BODE dedicated storage for the NIH-funded Genomic-based research projects - 3.5 PB
  • IBM ESS BE (Big Endian): default location for all data and very highly utilized - 6 PB
  • IBM ESS LE (Little Endian): newest data storage (Available in Q1 2018) - 4 PB

High speed Interconnection: Mellanox Fourteen Data Rate (FDR 56 Gbps)

Spectrum Scale version: 4.1

We are happy to announce that we have purchased 4 PB of new data storage and 260 TB of new flash. This upgrade will add to the current ESS storage that has been recently added to provide a total of 9PB of storage. This will satiate the current demand of 8 PB project space and will provide the space needed after the retirement of our Flash, DDN10K and GSS systems (EOL in 2018).
The new data storage is composed by 1 rack of the newest IBM ESSGL6S system which is going to provide roughly 30% increase in performance in a drive to drive comparison.
The new flash storage is going to replace the old one granting more read/write bandwidth and storage space to the metadata tier.
We will keep you posted on the timeline and outages necessary to incorporate this new storage in Minerva.
