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 user: kerberos pass: kerberos pass

Getting Started

Getting Started requires access to a SSH Client-

• SecureSSH is available here : ftp://metalab.unc.edu/pub/packages/security/ssh/SSHSecureShellClient-3.2.9.exe

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: Right Click on "my computer" Select "Map Network drive" Enter Folder "\\bmc-pub1.mit.edu\labname" Select "different username" Add your username and password

Macintosh cifs://bmc-pub1.mit.edu/labname HIT the + save select the path click it Connect Confirm : workgroup Name (email) password enter

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: Please note - the user must be "root" or given "sudo" access to mount a drive" 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" Make sure the directory is created. Type in "ls-al"  %/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 Now you have the ability to copy / delete files via command line to the /mnt/bmc-pub1 directory as it was a local to the machine. To delete or remove the mount point At the / location Type umount -f /mnt/bmc-pub1 <enter> check the mount point is gone df -h <enter>"
