General Information
The BioMicroCenter Public Server (BMC Pub1) new service offered by the center is geared to provided inexpensive server based storage for labs and facilities. This server is operated on annual fee basis. Details about the server are:
- 16 TB Thinkmate server.
- 2-QUAD Core Intel Xeon E5462-2.8 Ghz CPU
- 16 GB RAM
- The system runs Red Hat Enterprize Linux 5.3 supported in a RAID 1 configuration (mirrored)
- The data partition is configured in a RAID 6 configuration with a "hot spare".
- The device supports SMB, CIFS, and SSH connections from the MIT campus (or by VPN).
- Backed up by MIT's TSM service
- Machine administration by the Biomicro Center.
PLEASE NOTE:
- This computer is not meant for heavy computation!
- Use is offered and limited that of a storage server.
- Computational processes may be terminated without notice.
- The server is currently in BETA. This means we will work as hard as we can to have everything working, but there may be kinks in the system.
Folder Structure and Pricing
The public server is being offered to provide a service to the community. A cost recovery strategy is being employed to fund the investment.
Pricing
- The yearly lease cost for one terabyte is $500.00 per year.
- The volumes can be dynamically increased to allow for increase space inside the existing file structure.
Folder Structure
Default base folder names:
NAME | TYPE | EXAMPLE |
---|---|---|
center | centername: | biomicro |
lab | labnamelab | levinelab |
Each terabyte is preformatted as follows (using BioMicro Center as an example):
Unix path | Windows / Mac path | Permissions |
---|---|---|
/data/biomicro | \\bmc-pub1\biomicro | Access limited to members of the lab/group |
/data/biomicro/public | \\bmc-pub1\biomicropub | Public directory to allow filesharing between groups |
/data/biomicro/user/homedirs | \\bmc-pub1\homes | Private home directory of user |
data/biomicro/user/username | Unix access | SSH Access: Host: bmc-pub1.mit.edu |
Getting Started
Getting Started requires access to a SSH Client-
- SecureSSH is available here : http://18.79.4.105/
- SSH-Command-line&TransferClient_installer
Connect to the server :
- host bmc-pub1.mit.edu
- user email name
- pass kerberos password
- port 22
If you logged in correctly, you should be at the "bash prompt".
There is a default samba password in a file called ".sambaword"
- type : more .sambaword <enter> - your temporary samba password will appear.
- type : smbpasswd <enter>
- at the prompt, enter your temporary password.
- enter and confirm your new password
You should now be able to access the server from PC and Mac
Biomicro Center Public Storage Server Connection Windows and MAC
Windows
BMC-Pub1 is accessed as a "mapped drive". To do this:

Biomicro Center Public Storage Server Connection "Command line using an SMB mount"
SMB or Cifs mount from a UNIX System
BMC-Pub1 can accessed as a "mounted drive from a UNIX system". To do this:
Create a mount point on the system * Please ssh into the system * Move to the "\mnt" on the filesystem * Create a directory as a mount point: type "mkdir bmc-pub1"
%/mnt/bmc-pub1 should appear The "mount command" The mount command requires the location the Windows Share. The mount point provides access as this user. It is recommended to delete after use. mount -t cifs -o username=bozo,password=clown //bmc-pub1/yoursharename /mnt/bmc-pub1 <enter> If there is no error message the command mounted the drive. There is a command to check the status of all mounted drives. It is known as the "df-h" An example might be df-h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 72G 2.3G 66G 4% / /dev/hda1 99M 9.0M 85M 10% /boot none 506M 0 506M 0% /dev/shm //bmc-pub1/biomicro 1008G 52G 957G 6% /mnt/bmc-pub1
To delete or remove the mount point At the / location Type umount -f /mnt/bmc-pub1 <enter>

Biomicro Center Public Storage Server Connection "SCP EXAMPLE"
Command line file copy from system to BMC-PUB1 UNIX System
You too can do a command line copy of a "file or folder" using SSH. It is known as SCP. Required: *User account on the system *Knowing beforehand the location you have the permissions to access. Reference: http://www.hypexr.org/linux_scp_help.php Provides many examples. This example we will copy a file:
Move into the directory of the file you wish to copy via ssh * Type in "ls -al" to view the contents of the directory. * scp nameoffile username@host:/locationofremotecopy * scp mit-krb-config-1.0-3.noarch.rpm sgoldman@bmc-pub1.mit.edu:/data/biomicro *The authenticity of host 'bmc-pub1.mit.edu (18.79.4.104)' can't be established. RSA key fingerprint is 15:e5:de:a3:dc:8a:02:38:bb:a9:61:7b:c4:63:d0:42. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'bmc-pub1.mit.edu,18.79.4.104' (RSA) to the list of known hosts. sgoldman@bmc-pub1.mit.edu's password: <enter your password on the remote system> *mit-krb-config-1.0-3.noarch.rpm 100% 4433 4.3KB/s 00:00 <transfer> File copied.
