DATA Matrix
The Data Matrix code is a two-dimensional code that packs significantly more information into a given area than comparable coding techniques such as, for example, the well-known bar code. Data Matrix is a compact symbology where the information to be encoded is represented on a square or rectangular area in the form of a dot pattern. In contrast to the one-dimensional bar code, which involves reading a sequence of parallel lines of different thickness, reading a Data Matrix code involves explicitly determining the arrangement of the dots in the grid inside the framed area.
In the data centre, 2D labels form the basis for a number of interesting initiatives in the areas Inventory, Monitoring/Service and Security, e.g.:
- identification and inventory of assemblies in server racks
- on-site monitoring and operation of rack components using a mobile phone or PDA
- access control to the rack entering a PIN code via the mobile phone
The individual information is encoded on the 2D label and read with a software program. The codes are simply attached inside or onto the rack.
- Readable ASCII tags
- e.g.: Server MAC 00-B0-D0-7B-A1-EC
- e.g.: CMC-TC SN 05497
- Coding of up to 1554 bytes
- Higher information density for the same data content and structure size
- Reed Solomon error correction (readable > 75 %) ensures high redundancy and data reliability
- Identification e.g. via digital camera, camera mobile phone, PDA with camera
