For Edge computing and core business workloads
Minimise data centre space and run workloads at the edge, while maintaining the performance, security, and reliability of an enterprise server.
The three main operating systems are:
AIX (UNIX developed by IBM with cooperation from Bull between 1992 and 2022, known for its robustness and ability to handle heavy workloads);
Linux, notably Red Hat Enterprise Linux (RHEL), which is certified on Escala (known for its standardisation and commercial support);
IBM i, which integrates a database (often used for processing financial transactions and running business applications requiring high availability and reliability).
ARF, or Application Rollover Facility, is a HA/DR solution developed by Bull in France since 2002 that makes it easy to move an application from one partition to another in order to ensure availability of your application, if you get maintenance or system / hardware failure. It uses storage array replication technology, and since the solution is storage-agnostic, it is not limited to IBM array brands.
OEM Escala and Bull R&D began collaborating with IBM research centers, notably in Austin, Texas, in 1992 to work on AIX, SMT technology, Live partition Mobility, Live Update, the kernel debugger (kdb), etc.
Escala provides open and flexible solutions, offering a wide range of configurations and cost‑effective value‑added alternatives, including flexible consumption models and financing. You benefit from Bull’s technical and industry experts for business‑critical applications and infrastructure services. Escala is 100% compatible with IBM Power, AIX and the full ecosystem, while giving customers multiple options for storage and software solutions.
