SciStor
What is it?
The storage service SciStor is intended for cheaply storing large amounts of research data.
SciStor is hosted by IT for Research (ITvO) on the VU campus enabling a high-speed connection to lab equipment, laptops and workstations, the BAZIS HPC cluster and SciCloud. It can also be accessed off-campus.
Your data is stored in a share, basically a folder with group-based access rights (read/write or read-only). Access rights can be set one level deep, so one share could be used to host data from different projects.
If desired, automatic backups can be made of the data.
What can it be used for?
Networked Drive
Because SciStor is connected to the VU on-campus network you can directly mount (map a network drive) SciStor shares on your laptop and work as if the data is on a local disk.
Access off-campus
Although SciStor is most useful on campus you can also access your shares off-campus.
Lab instruments
In many cases lab equipment can write data directly to SciStor. IT for Research can help you setup an automated and secure connection.
Storage space for SciCloud servers
SciCloud virtual servers are provisioned with a 20 to 50GB local disk. A SciStor share can be directly mounted on the server to increase storage for your application or directly access your source data for analysis.
BAZIS
The BAZIS HPC cluster is connected to SciStor via a high speed netwodrk. You can run your analysis software directly on your data and easily access the results on your laptop.
Data life-cycle
SciStor is meant for data you are actively working with. We recommend archiving datasets that are no langer actively used, but can’t be deleted, in Yoda. This ensures SciStor is used optimally and costs are kept down for your research group and the VU.
How to request access
Are there costs involved?
You pay for the amount of space reserved for your share: €0,10 per GB per year without backup or €0,20 per GB per year with backup. Note that without backup data will be lost in case of accidental deletion or major problems with the SciStor infrastructure.
If activated, backups will be made using the ‘snapshot’ technique. The backup data is stored at an off-campus data centre to ensure your data is protected against disasters.
The owner of the SciStor share receives monthly usage reports. The report provides insight on used and available space.
Getting started
On-campus access
- MacOS
- Open the Finder application
- In the “Go” menu, pick “Connect to Server…”
- Fill in:
smb://scistor.vu.nl/shares
- Click “Connect”
- Select “Registered User” if this is not yet selected
- Fill in your VUnetID and password
- Press “Connect”. Optionally, tick the “Remember this password in my keychain” checkbox. After doing this, macOS will no longer ask for credentials the next time this connection is used.
SciStor shares appear on the left after opening the SciStor location. You may open the desired SciStor share by double-clicking it.
- Windows
- Open Windows File Explorer
- Right-click on This PC and choose “Map network drive…””
- Select a desired drive letter, for example S. In the Folder field you can enter the following:
\\scistor.vu.nl\shares\<the name of the share folder>
. Make sure the checkboxes are checked. - Click “Finish”
- You will now be asked to log in. This is not possible with your PIN code. Choose the “More choices” option, and log in with your VU email address and password
- ‘Green’ Linux workspaces
Green Linux workplaces (supported by VU IT) have a connection to SciStor from home. All SciStor shares can be found under the path /research
.
- Other Linux workstations
Other self-managed Linux workstations can also connect to SciStor.
Via the SMB protocol: Modern Linux variants have the ability to connect to shares from the GUI via the SMB protocol. SciStor shares can be linked with this SMB address: smb://scistor.vu.nl/shares
.
Via the SFTP protocol: SciStor with the SFTP protocol can be used via the server sftp.data.vu.nl
. Find the shares under the path /research
.
Off-campus access
- eduVPN
The easiest way is to install the app for eduVPN institute access. Once the VPN is active you can follow the “on-campus access” steps above. Note that performance over the internet is limited, you might run into problems when editing large files. If needed copy them to you local disk.
- SFTP
On windows you can use a free tool like WinSCP or CyberDuck to access your data via the SFTP protocol. The server URL is sftp.data.vu.nl
, find the shares under the path /research
.
On a Mac you can connect via the IT supported 🔒 Expandrive (follow the SFTP instructions).
