Ensuring Reliability and Availability

Reliability and Availability are critical components of your hosting infrastructure, ensuring that your services remain accessible and operational at all times. Let’s delve into how Digital Craftsmen helps businesses growth by expertly balancing these critical aspects:

Reliability:

Reliability quantifies the likelihood of equipment to operate as intended without disruptions or downtime. It’s measured by metrics like mean time between failure (MTBF) and failure rate. To improve reliability, our managed services offer proactive measures such as:

  • Data Collection: We collect comprehensive data on equipment health and failure modes to identify potential issues before they escalate into significant problems.
  • Failure Mode and Effects Analysis (FMEA): By analysing failure modes and their impact, we prioritise preventive maintenance tasks to minimise disruptive breakdowns.
  • Optimised Maintenance: We optimise maintenance practices, streamline PM scheduling, and improve MRO inventory management to reduce downtime and enhance equipment reliability.
  • Continuous Improvement: Our approach focuses on continuous improvement, leveraging data-driven insights and implementing new technologies to further enhance reliability over time.

Availability:

Availability, also known as operational availability, is expressed as the percentage of time that an asset is operating compared to its total scheduled operation time. To calculate availability, you can use the following formula:

Availability (%) = (actual operation time / scheduled operation time) x 100%

Actual operation time represents the total length of time that the asset is performing its intended function, while the scheduled operation time is the total period when the asset is expected to perform work, excluding idle time. Ideally, assets should have as close to 100% availability as possible, with world-class availability being 90% or higher.

Steps to improve availability include:

  1. Measure Your Current Availability: Determine how many hours out of your scheduled time your equipment is in operation and render that as a percentage to understand your baseline.
  2. Determine Achievable Availability: Benchmark your availability against industry standards, considering factors like manpower, spare parts, and maintenance practices, to establish achievable targets.
  3. Update Operational Practices: Streamline operational procedures to minimise limitations on equipment availability and performance, ensuring seamless operation.
  4. Implement Effective PM Practices: Focus on preventive maintenance to avoid equipment breakdowns and optimise PM scheduling to reduce unnecessary downtime.
  5. Improve Scheduling Practices: Enhance scheduling practices to ensure timely availability of equipment and parts, accounting for factors like location, skill limitations, and task priority.
  6. Implement Predictive Maintenance: Utilise predictive analytics and sensors to proactively monitor assets and anticipate maintenance needs, minimising downtime and optimising resource allocation.

By focusing on both Reliability and Availability, Digital Craftsmen always makes sure your hosting infrastructure is robust, resilient, and capable of delivering uninterrupted services to your valuable customers.
