Robustly built to serve multi-store, high transaction volume, or large format retail enterprises, the plug-and-play digital® Enterprise Controller (dEC) is the powerhouse among dedicated appliance controllers available on the market today.
Engineered from the ground up to securely keep your Catapult retail automation system running 24/7 with minimal user interaction, dEC provides the enterprise protection expected and required from a dedicated controller. ECRS’s dEC operates with Linux™ technology and is designed for the sole purpose of behind-the-scenes management of your Catapult system. Because of this, the chances of virus infiltrations are greatly reduced, preventing system crashes, data loss, and increasing speed and performance.
The Intelligent Platform Management Interface (IPMI) is a set of ECRS digital Controller interface specifications for an autonomous computer subsystem that provides management and monitoring capabilities independently of the host system’s CPU, firmware (BIOS or UEFI) and operating system. IPMI defines a set of interfaces used by system administrators for out-of-band management of the controller system and monitoring of their operation. For example, IPMI provides a way to manage a server that may be powered off or otherwise unresponsive by using a network connection to the hardware rather than to an operating system or login shell.

What is RAID 10?
RAID is a Redundant Array of Independent Drives, in this case, Micron M600 512GB SED SATA 6Gbps 2.5State Drives (SSD’s). It is a method of storing information on multiple drives for greater protection and performance. Under the RAID umbrella, there are a number of different storage methods, called levels, and numbered from 0 to 9, some of which are more useful than others. Each level is a distinct method of organizing storage, but some of them can be combined. This produces a two-digit RAID level, such as RAID 10, sometimes identified (and more appropriately so) as RAID 1+0. RAID 10 is fast and its crash proof.
How does it work?
RAID 10 works by striping and mirroring your data across at least two disks. Mirroring, or RAID 1, means writing your data to two or more disks at the same time. Even if one disk fails completely, the mirror preserves the information. Striping, or RAID 0, means breaking your data up into chunks and writing the chunks to different disks in succession. It improves performance because the computer can get data off more than one disk simultaneously. When you put RAID 1 and RAID 0 together you get RAID 10. RAID 10 is secure because it is mirroring duplicates all your data. It’s fast because the data is striped across two or more disks, meaning chunks of data can be read and written to different disks simultaneously.
Does RAID 10 Back up my data?
RAID is no substitute for back-up!
All RAID levels except RAID 0 offer protection from a single drive failure. For complete security, you do still need to back-up the data from a RAID system.
- The back-up will come in handy if all drives fail simultaneously because of a power spike.
- It is a safeguard if the storage system gets stolen.
- Back-ups can be kept off-site at a different location. This can come in handy if a natural disaster or fire destroys your workplace.
- The most important reason to back-up multiple generations of data is user error. If someone accidentally deletes some important data, and this goes unnoticed for several hours, days or weeks, a good set of back-ups ensure you can still retrieve those files.
Although data is written and mirrored on to two disks simultaneously, the data is not being backed up. Should your system, rather than the hard disk, suffer an error; erroneous data could be sent to both disks at the same time, corrupting both drives simultaneously. You still must have a backup strategy in place, such as the ECRS cloud back up plan.
