The Intel SSD 910 Series is a PCIe-based expansion card for high-performance storage solutions. A Secure Erase for this device is performed with Intel's own command-line tool (Data Center Tool). In this article, it will be explained how to perform a Secure Erase using the Intel Data Center Tool.
Downloading the Datacenter Tools
The Intel Data Center Tool can be obtained free of charge from the Intel Download Center:
After successfully downloading and unpacking the archive, you will find the following files:
:~/Downloads$ tar xf Intel\ SSD\ Data\ Center\ Tool\ 1_1_0\ Linux.tar -C intel-datacenter/ :~/Downloads$ cd intel-datacenter/ :~/Downloads/intel-datacenter$ ls Intel SSD Data Center Tool License Oct 2012.rtf Intel SSD Data Center Tool User Guide 327191-002US.pdf* isdct*
The command line program isdct can be easily copied for later use as /usr/local/bin.

To know which device path has been mapped to which device, it is recommended to control the SAS Addresses:
:~$ lsscsi | grep 910 [6:0:0:0] disk INTEL(R) SSD 910 200GB a40D /dev/sdg [6:0:1:0] disk INTEL(R) SSD 910 200GB a40D /dev/sdh :~$ ls -l /dev/disk/by-path/|grep sdg lrwxrwxrwx 1 root root 9 Jan 25 14:33 pci-0000:05:00.0-sas-0x5000cca0130055b1-lun-0 -> ../../sdg :~$ ls -l /dev/disk/by-path/|grep sdh lrwxrwxrwx 1 root root 9 Jan 25 14:33 pci-0000:05:00.0-sas-0x5000cca0130055b6-lun-0 -> ../../sdh
Comparing the SAS addresses and device information results in a mapping of:
/dev/sdg -> 5000CCA0130055B1 -> Device 0 / Drive 0 /dev/sdh -> 5000CCA0130055B6 -> Device 0 / Drive 1
Performing the Secure Erase
Using the erase command a Secure Erase can be initiated:
:~$ isdct -help | grep erase
-erase Erase all the data on the drive by issuing a SCSI Format Unit command.
Use -drive all to erase all the target drives in parallel.
Example: isdct.exe -device 0 -drive 1 -erase
Both the correct device and the correct drive must be specified:
:~$ sudo isdct -device 0 -drive 0 -erase
[...]
Erasing the drive...
SUCCESS
In this case, the Secure Erase must be confirmed once more prior to running. The additional parameter -force has eliminated this aspect.
