This round has been closed as all proposals have been handled.
NAISS storage is working storage while actively processing data. It is typically highly stable, but there are no backups, data loss can occur, and it should not be entrusted with the only copy of valuable data.
The storage must be for use together with current or future NAISS compute projects.
To apply, you must be a scientist in Swedish academia, at least at the level of PhD student
.
Deadlines and Decisions
Proposals are processed weekly. Storage proposals related to compute proposals will be handled after a decision is taken on the related compute proposal.
Note that staff will be on vacation during the summer and proposals submitted in July will be processed at a reduced pace.
This round is open for proposals until 2026-01-01 00:00.
Storage attached to Alvis and Vera at C3SE.
Please use Mimer if you only use Alvis.
Please note that all NAISS allocattions on Cephyr NOBACKUP will end 2026-06-30.
Project storage based on Ceph with a total usable area of 5 PiB.
14 Storage servers, each with 3 NvMe:s (for database and journal).
The preferred project storage resource for Alvis. Currently only available from Alvis.
Currently only available from Alvis.
This is the preferred project storage resource for Alvis.
Allocations on Mimer will be scaled and transferred to storage on the new NAISS system Arrhenius. It is NAISS's best estimate now that this will occur in the spring of 2026. More information will be announced as procurement and installation of Arrhenius progresses.
Project storage attached to Alvis and Vera, dedicated for AI/ML
Mimer is an all-flashed based storage system based on as solution from WEKA IO.
It consists of an 0.6 PB all-flash tier and a 7 PB Ceph based bulk storage tier (with spinning disk).
Storage on Centre Storage at NSC for compute projects allocated time on NSC resources.
Centre Storage at NSC is designed for fast access from compute resources at NSC. The purpose is to provide storage for active data for NAISS compute projects allocated time on compute resources at NSC.
Apply for a file quota of 1 million files unless you have a good motivation for more. Proposals will be evaluated within a few working days.
Allocations on Centre Storage will be scaled and transferred to storage on the new NAISS system Arrhenius. It is NAISS's best estimate now that this will occur in the spring of 2026. More information will be announced as procurement and installation of Arrhenius progresses.
Project storage for NAISS as well as LiU Local projects with compute allocations on resources hosted by NSC.
Centre Storage @ NSC is designed for fast access from compute resources at NSC. It consists of one IBM ESS GL6S building block and one IBM ESS 5000 SC4 building block.
In total there are 946 spinning hard disks and a small number of NVRAM devices and SSDs which act as a cache to speed up small writes. The total disk space that is usable for storing files is approximately 6.9 PiB.
Storage attached to Dardel at PDC. Allocations on Klemming will be scaled and transferred to Arrhenius from 2027-01-01.
Storage for active data used by projects with compute allocations on Dardel. More information about project directories in Klemming can be found at https://www.pdc.kth.se/support/documents/data_management/klemming.html.
NAISS will terminate operation of Klemming on 2027-01-01 as the compute resources Dardel, Dardel-GPU and Dardel-GH will be terminated on that date. Allocations will be transferred to Arrhenius from that date.
Project storage for NAISS as well as PDC projects with compute allocations on resources hosted by PDC.
Klemming is designed for fast access from compute resources at PCD. It uses the Lustre parallel file system, which is optimized for handling data from many clients at the same time. The total size of Klemming is 12 PB.
NAISS can currently only approve storage on dCache at Swestore until 2026-04-01.
Swestore is a Research Data Storage Infrastructure, intended for active research data and operated by the National Academic Infrastructure for Supercomputing in Sweden, NAISS,
The storage resources provided by Swestore are made available for free for academic research funded by VR and Formas through open calls such that the best Swedish research is supported and new research is facilitated.
The purpose of Swestore allocations, granted by National Allocations Committee (NAC), is to provide large scale data storage for “live” or “working” research data, also known as active research data.
