Greenplum Database is an open-source, massively parallel processing (MPP) system built on PostgreSQL. It is designed for analytics, machine learning, and data warehousing at enterprise scale. As datasets grow into terabytes and petabytes, storage performance becomes one of the biggest factors in maintaining cluster efficiency.
Simplyblock provides NVMe-over-TCP storage and zone-independent volumes, giving Greenplum clusters the resilience and throughput they need. Together, they enable large-scale analytics without the bottlenecks of traditional storage.
Why Storage Architecture Matters in Greenplum
Greenplum distributes data across multiple segments that work in parallel. Each segment relies on disk I/O for scanning, joins, and aggregations. If storage falls behind, query response times increase, and scaling becomes expensive.
Simplyblock offers high-throughput volumes that keep pace with segment operations while maintaining availability across zones. This prevents downtime during infrastructure shifts and ensures workloads remain stable.

Step 1: Setting Up Volumes for Segment Data
Greenplum segments need dedicated volumes for optimal performance. Create a simplyblock pool and connect volumes to store primary segment data:
sbctl pool create gpdb-pool /dev/nvme0n1
sbctl volume add gpdb-seg1 200G gpdb-pool
sbctl volume add gpdb-seg2 200G gpdb-pool
sbctl volume connect gpdb-seg1
sbctl volume connect gpdb-seg2
Format and mount the volumes:
mkfs.ext4 /dev/nvme0n1
mkdir -p /data/seg1
mount /dev/nvme0n1 /data/seg1
Repeat this for additional segments. These logical volumes provide the foundation for storing Greenplum’s distributed data.
Step 2: Directing Greenplum Segments to Simplyblock
Once volumes are mounted, configure Greenplum to use them. Edit the gpinitsystem configuration to define segment data directories:
declare -a DATA_DIRECTORY=(/data/seg1 /data/seg2)
Initialize or restart the cluster:
gpinitsystem -c gpinitsystem_config
This setup ensures that segment databases operate on high-performance volumes. Administrators can follow detailed instructions in the Greenplum installation guide to fine-tune initialization.
Step 3: Adjusting Storage Capacity for Growing Tables
As data warehouses expand, Greenplum segments require additional capacity. With simplyblock, volumes can be resized dynamically:
sbctl volume resize gpdb-seg1 400G
resize2fs /dev/nvme0n1
This allows queries to continue running while storage expands. Organizations running hybrid deployments can take advantage of multi-cloud storage options to scale efficiently across environments.
Step 4: Maintaining Availability Across Zones
Greenplum clusters often run across zones for reliability. Traditional storage tied to a single zone increases failover risk. Simplyblock overcomes this by supporting zone-independent volumes, ensuring that segments remain accessible even during reschedules.
This strengthens availability and works in line with fast backup and disaster recovery solutions that enterprises rely on for analytics workloads.
Step 5: Safeguarding Data with Replicated Volumes
To minimize downtime during infrastructure failures, simplyblock supports replication of Greenplum volumes across multiple zones:
sbctl volume replicate gpdb-seg1 –zones=zone-a,zone-b
This reduces recovery point objectives and improves failover performance. More guidance on replication strategies is available in the Greenplum high-availability documentation.
Operating Greenplum at Enterprise Scale
At a large scale, Greenplum requires both storage performance and simplified administration. Simplyblock reduces overhead with CLI-driven provisioning and scaling, giving administrators more time to focus on analytics.
Capabilities such as kubevirt storage extend deployment options, while integrations with containerized environments allow for flexible modernization. For advanced operations and storage management, administrators can reference the simplyblock Documentation as part of their workflow.
Questions and Answers
Simplyblock accelerates Greenplum Database queries by reducing storage latency and boosting throughput with NVMe over TCP. Complex analytics and parallel workloads complete faster because storage no longer becomes a bottleneck.
Yes, simplyblock integrates with Kubernetes through its CSI driver to support databases on Kubernetes. This ensures Greenplum Database nodes can persist data reliably while scaling dynamically across the cluster.
Absolutely. With features like encryption-at-rest, snapshots, and replication, simplyblock provides enterprise-grade durability and compliance. These capabilities allow Greenplum Database to handle production-scale distributed analytics workloads without risk of data loss.
Compared to standard cloud disks, simplyblock delivers more predictable latency and higher IOPS. This is crucial for Greenplum Database queries that depend on fast parallel reads and writes across large datasets, avoiding performance slowdowns common with generic storage.
Simplyblock ensures consistent performance whether Greenplum Database runs on-premises, in private cloud, or across public clouds. Its data management simplification features streamline operations while reducing complexity in hybrid setups.
