有同事反馈ftp上传ncbi非常慢,远程测试下2个进程上行共在600KB-1MB/S,给开到最大10个线程,上行有30Mbps/s。看了下防火墙日志一小时能上传10GB左右,170GB十七小时左右可以传完。
但是有更快的上传方式就是使用Aspera工具,于是注册了个帐号,建个sra上传任务,测试了下发现需要下载ssh key。一时找不到在哪下载,给[email protected]发了份邮件咨询怎么下载。下面是回复内容。
The ssh key is now available for download from submission portal. Click the "key file" link on this page:
https://submit.ncbi.nlm.nih.gov/subs/sra/#files_upload_aspera_cmd
There are more upload instructions here: http://www.ncbi.nlm.nih.gov/sra/docs/submitfiles .
The SRA Team
National Center for Biotechnology Information | National Library of Medicine
National Institutes of Health, Bethesda, Maryland 20892
打开链接https://submit.ncbi.nlm.nih.gov/subs/sra/#files_upload_aspera_cmd
展开"Upload via Aspera command line or FTP"

看到这个keyfile点击下载,还有下页会自动生成一个专用目录

下面是我测试上传的命令
"C:\Program Files (x86)\Aspera\Aspera Connect\bin\ascp.exe" -i "d:\aspera.openssh" -QT -l400m -k1 -d "d:\bioproject.xml" [email protected]:uploads/邮箱前缀_邮箱域名_生成的随机码

3163MB的文件9分钟多上传完。
