Maximizing Elasticsearch Speed with Simplyblock Storage

Elasticsearch powers real-time search and analytics across industries. Its ability to index and query massive datasets makes it invaluable for applications like log monitoring, product search, and security analysis. But as indices grow, traditional storage often introduces latency, limiting Elasticsearch performance.

Simplyblock solves this challenge with NVMe-over-TCP storage and a zone-independent design. By combining Elasticsearch with simplyblock, enterprises unlock faster indexing, improved stability, and seamless scaling across zones.

Why Elasticsearch Demands High-Performance Storage

Elasticsearch’s core operations—indexing documents and executing queries—depend heavily on storage. Slow I/O causes delayed writes, slower queries, and unbalanced clusters. Without optimized storage, the system struggles to maintain performance at scale.

Simplyblock provides high IOPS and low-latency storage, allowing Elasticsearch to process heavy indexing and search workloads smoothly. Its zone-independent design also ensures consistent uptime during node or infrastructure changes, making it ideal for enterprise-scale clusters.

Step 1: Preparing Storage Pools for Elasticsearch Data

The first step is to create a simplyblock pool and logical volume for Elasticsearch. These volumes provide the backbone for index storage.

sbctl pool create es-pool /dev/nvme0n1

sbctl volume add es-data 300G es-pool

sbctl volume connect es-data

Once connected, format and mount the volume:

mkfs.ext4 /dev/nvme0n1

mkdir -p /var/lib/elasticsearch

mount /dev/nvme0n1 /var/lib/elasticsearch

Adding the mount to /etc/fstab ensures it persists across restarts:

/dev/nvme0n1 /var/lib/elasticsearch ext4 defaults 0 0

This setup allows Elasticsearch to store data directly on simplyblock volumes, enabling consistent indexing performance even under heavy workloads.

Step 2: Directing Elasticsearch to Optimized Volumes

After mounting, Elasticsearch must be configured to use the simplyblock-backed storage path. Update the configuration file elasticsearch.yml:

path.data: /var/lib/elasticsearch

Then restart the service:

sudo systemctl restart elasticsearch

This ensures Elasticsearch writes data to high-speed simplyblock volumes. For advanced tuning, administrators can adjust additional cluster parameters outlined in the Elasticsearch setup guide.

Step 3: Expanding Elasticsearch Capacity on Live Clusters

Growing indices demand additional space, and traditional scaling methods often cause downtime. Simplyblock allows seamless volume expansion without disrupting the cluster:

sbctl volume resize es-data 600G

resize2fs /dev/nvme0n1

This live scaling ensures queries and indexing continue uninterrupted. Features like disaggregated storage further reduce overhead by separating compute and storage, allowing Elasticsearch clusters to expand more efficiently.

Step 4: Running Elasticsearch Across Availability Zones

Elasticsearch clusters often span multiple zones to maintain resilience. Standard storage adds complexity to these setups, but simplyblock enables zone-independent volumes that remain accessible even when nodes are rescheduled.

This capability ensures that data remains available during outages and strengthens continuity plans. Enterprises also benefit from simplified recovery strategies, which align well with fast backups and disaster recovery practices.

Step 5: Building Resilient Elasticsearch Clusters with Shared Volumes

For clusters to handle heavy search and replication workloads, storage must support quick failover and consistent durability. Simplyblock makes this possible by enabling shared volumes across multiple zones:

sbctl volume replicate es-data –zones=zone-a,zone-b

This reduces both RPO and RTO, giving Elasticsearch clusters the ability to recover rapidly from failures. More guidance on cluster resilience can be found in the Elasticsearch high availability design guide.

Enterprise Storage Management for Elasticsearch

Managing Elasticsearch across multi-cloud and hybrid setups often introduces complexity. Simplyblock simplifies this with cloud-native commands for provisioning, scaling, and monitoring, allowing teams to focus on performance rather than infrastructure.

Capabilities such as kubernetes backup integrate directly with modern workloads, ensuring that clusters remain portable and resilient. For administrators seeking more in-depth operational details, the simplyblock Documentation provides technical references and best practices.
