Service constraints
FlexFS is an innovative cloud-native file system developed by Paradigm4 that transforms network-accessible object storage into a POSIX-compliant file system mountable across multiple hosts with concurrent access. A flexFS volume behaves like a traditional folder while delivering elastic throughput that scales with workload demands. It supports standard file utilities and workflows without special adapters or application rewrites.

The service is designed for data-intensive environments, including high-performance computing (HPC), AI/ML pipelines, large-scale analytics, scientific research, media processing, and enterprise file workloads that demand high throughput, concurrency, and predictable cost control.

Onboarding and offboarding

Getting started
Cirro – Cloud Migration Best Practice Standards
Cirro follows recognised, industry‑standard cloud migration best practices. This framework provides a structured and proven approach to planning, migrating, and optimising cloud environments.
Core Best Practice Framework
Cirro aligns its cloud migrations to the Microsoft Cloud Adoption Framework, which is wide-ly adopted as best practice for Azure migrations.
Migration Lifecycle Adopted by Cirro
• Analyse – Assessment of the existing environment, dependencies, risks, security and com-pliance requirements.
• Plan – Definition of migration strategy, workload prioritisation, timelines, rollback planning, and risk management.
• Transition – Phased migration using Azure-native tools to minimise downtime and disruption.
• Operate – Ongoing operational management, monitoring, security and cost optimisation.
• Transform – Adoption of cloud-native services and modern workplace technologies to im-prove performance and scalability.
• Continual Improvement – Continuous optimisation using lessons learned, service reviews and performance reporting.

In summary, Cirro delivers cloud migrations using best practice, supported by ISO-accredited quality, security and continuity standards. This ensures migrations are secure, low-risk, well-governed, and continuously optimised after go-live.

End-of-contract data extraction
At exit, we will deliver a structured, time-boxed handover ensuring you or your successor MSP receives all data in open formats:
 Databases: Native SQL .bak files (full/differential/log chain), CSV exports, schema docu-mentation.
 File Shares: Robocopy with ACL preservation, or packaged archive (ZIP/TAR).
 SFTP Zones: Structured export including logs.
 Configurations: AD, GPOs, RAS farm exports, SFTP configs, certificates (via escrow).
 Verification & Handover: Data integrity checked via checksums, with joint sign-off.
 Secure Destruction: Certified wiping of residual data post-handover.
This guarantees no vendor lock-in, UK-only handling, and a risk-free transition.
End-of-contract process
The contract and Sales Order will detail all the pricing elements for the delivery and running of the services as and when the agreement ends. The customer may wish to extend for an additional or shorter term, these commercial terms can be accommodated under G-Cloud guidelines / restrictions. Should the customer wish to exit at the end of the contracted term, then the Exit Plan will be invoked. This document looks at an exit plan including migrating services to another provider, to internal platforms or whatever other options have been detailed. This will also include likely costs. At this time a formal SoW will be produced to detail the level of involvement required from Cirro to transition services to another provider. This is charged on a Time & Materials basis, the rates of which are details at the start of the Agreement. A Customer may wish to request the new provider assists with the transition and therefore limiting assistance and costs from Cirro . Cirro will always look to provide professional support and assistance to reduce risk and maintain service during any major transition.

Scaling

Independence of resources
This is guaranteed by the architecture of the solution which is based on a network of hundred micronodes working in a peer-to-peer mode and therefore capable of processing simultaneously thousands of concurrent accesses to the system.
Furthermore, from a data separation standpoint, each user of the system is granted his dedicated space name which can be accessed only through user authentication which is based on a key-pair protocol. Only the public key is passed during the communication. The private key (delivered to user only) is used to cypher each request. user authentication

Availability and resilience

Guaranteed availability
99.99%
Approach to resilience
Resilience is built into the core fabric of our operations and cloud compute platforms, we build resilience in customer deployments against requirements. This approach ensures that as a business, we are highly resilient, and as a customer, you have the flexibility to have the right level of resilience based on required update, data loss sensitivity, risk and cost.
Everyday resilience:
 N+1 compute and storage design; dual PSUs, redundant networking.
 Dual PSUs and redundant network paths.
 HA clustering for Domain Controllers, File & Print, RAS Gateways/Hosts.
 SQL log backups every 15 minutes.
Outage reporting
All of the above

The request has to include: 1. Reason a. Improving security b. Improving performance or functionality c. Reduce operational overhead or cost 2. Request to be approved by SwARM’s: a. Service Manager b. System Architect c. InfoSecurity 3. Change request must include: a. Expected outcome b. Test plan c. Roll-back plan d. SoW
Vulnerability management type
Supplier-defined controls
Vulnerability management approach
All systems are scanned for vulnerabilities every month. Cirro uses the Common Vulnerability Scoring System (CVSS) for all Common Vulnerabilities and Exposures (CVE) provided by the National Vulnerability Database. Scoring for non-CVE vulnerabilities is provided by UB’s vulnerability scanning tool. A priority is placed on patching or mitigating the vulnerability based on these scores and the logical location of the vulnerability within The SwARM's network infrastructure. Remediation occurs within 10 business days for critical vulnerabilities.
Protective monitoring type
Supplier-defined controls
Protective monitoring approach
Our service management processes are ITIL aligned and have a particular focus on Security Incident Management System and Continuous Service Improvement. Some of the components of this system have been provided below: - Network and Host-based IDS/IPS - Traffic monitoring and intelligent traffic analysis - Packet capture and analysis to enable investigations into alerts - DNS monitoring to detect DNS lookups to known or suspected malware -
Incident management type

No
Incident management approach
Prevention: The understanding of and application of insight gained from the intelligence Detection: The interpretation of any events of interest occurring to discriminate between legitimate and abnormal events to identify anomalous activity Investigation: The analysis of anomalies to determine whether they are emerging threats that may lead to a security incident Reaction: Our analysts use tailored, predefined and configured Playbooks to efficiently inform their reaction to an identified threat Response: The planning of effective mitigation in response to the cyber-attack, the communication of these plans to all relevant stakeholders, and the collaboration with all relevant parties to carry out mitigation.

Description of energy efficient datacentres
This solution uses additional object storge. When used in conjunction with Wasabi we can conform data centres support energy efficiency by using a simplified object-storage architecture that reduces hardware complexity, power consumption, and cooling demand. By eliminating performance tiers and optimising storage density, Wasabi data centres lower energy use per terabyte while maintaining high availability and durability.
