In this session, speakers Giles Sirett and Philipp Reisner shared insights into CloudStack and LINBIT. Giles detailed Apache CloudStack’s scalability, multi-tenancy, and compatibility with various hypervisors. He also discusses CloudStack’s integrated, easy-to-use nature, rapid time-to-value, and its active community. Following this, Giles delves into different use cases, such as IaaS/Cloud Provisioning, Disaster recovery, Sovereign Clouds, and the list goes on. CloudStack’s features, including its support for Kubernetes clusters, its scalable architecture, high availability and other features were also discussed. Following this, Philipp highlighted the 4 key ways in which LINBIT can help an organisation: ‘Protecting data, Always Keeping Your Services On, Shaping Your Destiny and Exceeding with Best Performance”. Philipp also delved into the different reasons why LINBIT SDS is so fast, and what the next steps are for DRBD, LINSTOR and the LINSTOR Driver for CloudStack. ----------------------------------------- On October 10th 2023, ShapeBlue, Ampere Computing and LINBIT held a joint virtual event – Building Next-Generation IaaS. The event explored how the synergy between ARM, Apache CloudStack and LINBIT’s storage solutions can achieve a formidable price-to-performance ratio. There were a total of 3 sessions held by speakers from all 3 organisations.

Why is LINBIT SDS so fast?
Layout at volume allocation
• All participating machines have full replicas, which
machines participate determined when creating a
volume.
• Be faster at IO submission time
• Saving on CPU/memory
In Kernel data-path
• Reduce number of context switches
• Saving on CPU/memory resources
• Minimal latency for block-IO operations
• Optional load-balancing for READs
Hyper-Converged
Very well suitable for hyper-converged deployment
• Reduced network load for reads
• Reduces latency
• LINBIT SDS’ Low resource consumption leaves most
of CPU and memory for workload. About 0.5% of a
single core are consumed by DRBD under heavier IO
load (measured with an analytics DB)
Build on existing components
• DRBD, LVM, ZFS, LUKS, VDO, ...
• Help day2 operations by leveraging on the
opera tion teams prior knowledge
• Build on the shoulders of giants

Where are the IOPS numbers?
22 Million IOPS
• November 2019
• 12 nodes x86 (Intel)
• 25Gb network (Intel)
• Intel SSDs
• Blog post
25 Million IOPS
• March 2023
• 3 nodes ARM (Ampere)
• 100Gb network (Mellanox)
• Samsung SSDs
• Complete paper (21 pages)
Concrete results heavily depend...
• On the storage devices (NVMe-SSDs, PMEM)
• HCI , workload and storage device co-location
• Network switches and NICs
• CPU single core performance

30. www.linbit.com | www.shapeblue.com
Next Steps
DRBD
• TCP transport multi-pathing
• TLS encryption
• RDMA transport updates
• Improvements to handling I/O timeouts
LINSTOR
• Better handling of failing backing storage devices
• Prioritize LINSTOR control network traffic over bulk
DRBD traffic
• Improvements with clusters with many thousands of
storage resources
LINSTOR Driver for CloudStack
• Supported Hypervisors: KVM and XCP-ng
• VM snapshots (in addition to volume snapshots)
• Optional copying of snapshots to secondary storage
• Network switches and NICs
• Provisioning by copying in addition to provisioning by snapshots
