=== Folder Structure ===
Once you have logged via SSH - above - and taken ownership of your "SAMBA" access account you are ready to mapp a WINDOWS share to your account space.
Default base folder names:       
{|border="1" style="text-align:center"
!style="width:100px"|NAME                           
!style="width:100px"|TYPE

|centername:
| biomicro

|-
| lab

Each terabyte is preformatted as follows (using BioMicro Center as an example): 
   
{|border="1"

==Biomicro Center Public Storage Server Connection  "Command line using an SMB mount"==
{| border="1" align=middle
|cellpadding="2" valign="top" width=800%|'''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>"

|cellpadding="2" valign="top" width=800%|'''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:
*SSH into a remote system other than BMC-PUB1"
  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.

BMC-PUB1

The BioMicroCenter Public Servers is a service offered by the Center. The servers provided low cost server based storage for labs and facilities at MIT accessible from Linux, Windows and Macintosh operating systems. This server is operated on annual fee basis of $400 per terabyte. Details about the servers are:

  • 16 TB Thinkmate server.
  • 2-QUAD Core Intel Xeon E5420-2.5Ghz CPU with 32 GB RAM
  • The system runs Red Hat Enterprize Linux 5.3-5.5 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. VPN to MIT is required to access the server from off campus.
  • Backed up by MIT's TSM service
  • Machine administration by the Biomicro Center.

PLEASE NOTE:

  • This computer is not designed 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 use for over 3 years. Eleven labs are using the model today. There are a total of six servers of this type is use today offering over 35 TB of space to the community.

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.

  • The yearly lease cost for one terabyte is $400.00 per year.
  • The volumes can be dynamically increased to allow for increase space inside the existing file structure.
