Berlin, June 27th, 2023 simplyblock.io Cross-cloud unified data platform

IS A SOFTWARE-DEFINED DATA STORAGE TECHNOLOGY. We empower cloud builders with unified, efficient and secure data storage technology... simplyblock.io ... while sustainably powering next-generation workloads such as AI, ML or HPC

Data storage systems are either too expensive or incomplete With various storage types (object, block, and file) and systems, operations are complex and inefficient. New types of workloads (AI, HPC) are adding to complexity. Storage operations are complex High-end storage systems are based on proprietary hardware and are expensive - making them unsuitable for all storage needs. High-performance storage is pricy Regional CSPs struggle to provide storage-layer integration with hyperscaler clouds. Multi-cloud and hybrid cloud adoption with most of cloud builders having two different systems to address these two key challenges Problem While AWS, Google and Microsoft are capable of building in-house state-of-the art data infrastructure, thousands of other cloud builders rely on third-party solutions

Unified high-performance data platform based on NVMe-oF with seamless integration between block, file and object storage.

NON-CLOUD DATA CENTER EDGE DATA CENTER PRIVATE CLOUD Native integrations with all major cloud providers and cloud stacks Efficient data replication on block layer between clouds Vertical scaling without performance drop Truly cross-cloud High performance at low total cost of ownership (TCO)

Advanced hybrid cloud, high-performance, highly scaleable storage solution at significant cost advantages Database Operators (DBaaS) Cloud Service Providers (IaaS) Service Provider Use Cases Virtualisation Hosting Hyperscaler integrations Data Centers Primary storage with highest availability and durability requirements, including recovery from ransomware attack and multi-AZ Disaster Recovery High IOPS throughput , low latency primary storage for managed databases service

Retail, manufacturing, warehousing, energy SaaS providers Enterprise & SME Use Cases Fintech & banking Telecommunications Healthcare Affordable high-performance storage for databases, AI, ML and other mission-critical workloads Multi-AZ Container Orchestration Split workloads between regional and hyperscaler clouds (e.g. managed databases, advanced analytical, AI and ML services) Primary storage with highest availability and durability requirements, including recovery from ransomware attack and multi-AZ Disaster Recovery

Improved SLAs 01 02 03 Higher margins Smarter operations Pricing, SLAs and breadth of offering are key competitive differentiators for cloud service providers. All-round storage solution Higher availability and data durability with more IOPS and lower access latency. Data storage is usually a non- differentiating commodity service, which makes it cost sensitive. Single cluster operations with automated replication, failover, and recovery. 04 New range of products Future-proof technology for demanding next-gen workloads; compatible with public clouds to create new offerings (e.g. disaster recovery into hyperscaler clouds). Smarter operations with simplyblock

From 10 microseconds (+ drive) Ultra low access latency Up to 500.000 IOPS per CPU-core CPU efficient Outstanding CPU consumption-to- compaction ratio (average ratio 1 GB of raw to 3.5 GB of effective) Innovative compaction Key performance parameters Low raw/effective capacity overhead for high degrees of data protection and availability (~0.75) Protection & availability

Superior technology Ultra high performance (high IOPS, low latency) with innovative data compression technique, high CPU efficiency and compatibility with commodity hardware resulting in lower costs. One system approach Common architecture designed at the block level to be used for block, file, and object. "Offloading" of workloads from file and object systems to high-performance shared storage layer to simplify architecture. Cluster architecture Unparalleled scalability (up to 1024 storage nodes) allowing for single storage cluster operations. Avoids fragmentation of resource pools and optimizes storage utilization while simplifying operations. Cyberstorage features Recovery from ransomware attacks without data loss (zero-RPO) would be the first solution of such kind in the market making stored data more secure. What sets us apart?

STORAGE SYSTEM TYPICAL STORAGE ARCHITECTURE TODAY Replacing the old technology simplyblock combines best features of existing storage systems into one solution Different storage systems for high-performance workloads and object & file storage Cybersecurity features not available across all storage systems Complex operations with various types of hardware and network protocols Unified high-performance storage system providing for all the use-cases Simple operations with standard hardware (x86) and mainstream network protocols Integrated cybersecurity functions across whole storage Single storage system providing for all performance, cybersecurity and data protection needs No or limited compatibility with public cloud infrastructure Hybrid cloud offering with native AWS integration

Technology Innovations Distributed, directory-less clustering algorithm for data placement with linear performance scalability in ultra-high-performance (IOPS/CPU core) and ultra-low latency environemnts, purely based on x64 commodity hardware with local NVMe storage Highly optimized, distributed erasure coding rather than replication (opt. raw:effective ratio) Erasure coding overhead is only 2-3 us on a single core and allows for 1.000.000 IOPS/CPU core, safe restart in all sudden power loss scenarios "Transactional" block storage - variable write size atomicity, which is independent of write atomicity of underlying devices. Writes are atomic in the distributed environment across nodes and devices Compaction algorithm, which significantly outperforms existing compression/dedup services on resource consumption/reduction efficiency ratio (planned for later release) Point-in-time recovery from ransomware attack (planned for later release)
