cloud.biohpc.swmed.edu provides web-based cloud storage, accessible outside of the UTSW network. This is useful e.g. for transferring data to/form collaborators at other institutions.
cloud.biohpc.swmed.edu is accessible anywhere, and features:
Usage is logged and carefully monitored. The system cannot mount or access your internal BioHPC storage due to information security restrictions.
A comprehensive guide to the different BioHPC cloud storage services is available here,
Because cloud.biohpc.swmed.edu is a web-based system, certain limitations are imposed by the user's browser and operating system:
Cloud File Exchange FAQs
Q: How do I access home/project/work storage in cloud.biohpc.swmed.edu?
A: You cannot mount internal BioHPC storage space into the cloud.biohpc.swmed.edu interface due to information security restrictions. You must upload files to this space via a browser, WebDav mount from a PC/mac, or by copying files into this space from the lamella web interface. On the lamella web interface your cloud external file exchange is automatically mounted and visible as a folder named 'Cloud'.
Q: How do I access my cloud.biohpc.swmed.edu file exchange storage in lamella?
A: Since November 2016 your cloud external file exchange is automatically mounted and visible as a folder named 'Cloud' within the lamella web interface.
Q: How do I mount my cloud file exchange storage to my PC or Mac?
If you are using a Windows PC or mac, you can mount lamella to your PC or mac, so that you can access your cloud file exchange space using WebDAV.
Editing registry settings can cause problems if you inadvertantly change a setting other than those detailed in the procedure below. Contact biohpc-help if you need assistance.
To mount storage successfully onto a Windows PC you must first modify some settings by following the Microsoft KB article: http://support.microsoft.com/kb/841215
By default Windows limits the maximum size of WebDav downloads to ~50mb. To increase to 4GB:
Use regedit as in the KB instruction above, and navigat to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
Once Windows is configured correctly you can then mount your lamella storage as a Windows share by following the instructions below:
NOTE - The Mac Finder implementation of WebDAV is very unusual. You may find the instruction below do not work, in which case see the 'Cyberduck Alternative Method' below. WebDave using the finder is known not to work at least on OSX 10.10 Yosemite.
Cyberduck Alternative Method
If you cannot successfully use your lamella space as mounted above, it is possible to access it using an alternative WebDav client, Cyberduck, which is free software.
Q: Why is my file upload failing?
A: Is your file bigger than 2GB or 4GB? Because lamella is a web-based service there are file size limitation imposed by your web browser and/or operating system. To upload very large files, >4GB you must be using a 64-bit version of Google Chrome, on a 64-bit operating system.
Q: Why is access slow when mounted to my PC/Mac?
A: Cloud file exchange uses a web protocol called WebDav to mount onto your PC or mac. This protocol is slower than e.g. the way BioHPC clients mount BIoHPC storage. If you are connected to the wired campus network you can expect up to 100MB/s transfer speed on large files. If you are using campus WiFi speeds will be low - the WiFi is congested, and you may not have a good signal.
Q: What should I consider before syncing files to External Cloud?
A: Check the total size of your files, and the potential size in the future. Be sure that they are always less than 50 G for External cloud. Otherwise, the server may not upload all your files successfully. If the total size of your data on the cloud storage always < free space on you’re your, you may synchronize everything from Cloud to your computer, otherwise, choose what to sync.
You also need to consider security and privacye issues. You should not store any PHI or other sensitive data on the cloud external file exchange service without prior approval.
Q: What is the OwnCloud Client?
A: It works as Dropbox local client on your computer, except that it works with Lamella and external Cloud files, which comply with UTSW information security. Download and install OwnCloud client on your computer at: https://portal.biohpc.swmed.edu/content/software/.
Q: Are cloud external file exchange files being backed up?
A: Yes, the external cloud file exchange service is backed up weekly for disaster recovery. However, you should never use the cloud file exchange service as the only location for your data.
