Oak Filespace Types#
- Though all Oak spaces share the same namespace, we classify each Oak storage request into one of six
spacetypes:group,project,org,school,scg, andzfs. If you're not sure which space is right for you, we're happy to help guide you! Just send us an email at SRCC-Support@stanford.edu.
| Filespace Type | What is it for? | Who's Eligible? | Additional Considerations |
|---|---|---|---|
group | Filespace dedicated to a specific PI and their collaborators | Faculty doing sponsored research | Most common Oak storage option |
project | Filespace dedicated to a group of collaborators who span multiple PI groups. | Anyone with a PTA doing sponsored research at Stanford | |
org | Filespace shared among a Stanford Organization or Center. Usually spanning multiple PIs or subgroups | Please email SRCC-support@stanford.edu for additional information | |
school | Filespace shared among a Stanford School. Usually spanning multiple PIs or subgroups | Please email SRCC-support@stanford.edu for additional information | |
scg | Filespace used by the Genetics Bioinformatics Service Center's SCG cluster. | The SCG Informatics Cluster resources are available for use by labs engaged in genetics and bioinformatics research. | May also be referred to as lab_$PINAME. SCG storage is not accessible from Sherlock. More information at https://login.scg.stanford.edu/ |
filesystems (ZFS) | ZFS is not mounted to Sherlock, but has been beneficial in some narrow use cases like LFS shares. Most use cases are better served by Native Oak (Lustre-based) storage. | Please email SRCC-support@stanford.edu for additional information | Not accessible from Sherlock. Gateway required. Uncommon configuration and not generally recommended. |
Other common terms#
Gateway#
- Gateways are services that provide access to data on Oak through various applications or protocols. Oak is made up of many pieces of storage equipment. These pieces of equipment communicate using a high-performance fiber network technology called Infiniband.
- Gateways have connections to our Infiniband network, as well as the broader Stanford network. This allows our users to enjoy the performance advantages that our Infiniband network provides, while ensuring access through services and protocols that wouldn't otherwise be available in traditional network environments
Infiniband#
- Infiniband is a networking standard that features high bandwidth and low latency. The current Infiniband devices are capable of transferring data at up to 200 Gbits/sec with less than a microsecond latency. As of this writing, the popular Infiniband versions are HDR (High Data Rate) with 200 Gbits/sec and EDR (Enhanced Data Rate) with 100 Gbits/sec.
