Cloud servers scaled for transactional performance

IOPS instances deliver the fastest disk speeds in the Public Cloud range. They offer direct access to NVMe drives, each of which deliver 250,000 read/write operations per second. And like our other instances, you enjoy on-demand resources and hourly billing. These cloud servers are designed to host databases and big data applications.

What is an NVMe disk?

Unlike standard SSD disks, NVMe (Non-Volatile Memory Express) disks use NAND flash memory cells to store data. With their PCI Express connectors, which until recently were only used by devices like graphic cards, the bottleneck created by the SATA connection is cleared.

PCI Passthrough

IOPS instances have dedicated access to the hardware through the PCI Passthrough function, which provides all the power of the NVMe drive directly through the PCI bus. There is no virtualisation layer to access the drive, so you benefit from all of the available performance.

Some features of virtual instances are limited, such as snapshotting and live migration. Special care must also be taken when backing up the data on NVMe drives.

1-4 NVMe drives

OVH offers instances with between one and four NVMe drives, each of which offer 1.9 TB of storage. These configurations are useful when you need to process large volumes of data, and deliver exceptionally high performance.

Use cases

NoSQL - MongoDB database

MongoDB is a document-oriented database management system, and is often used within large infrastructures. It can manage high volumes of data, and often requires high levels of disk access. It can be used in a cluster, and can be deployed on several i1 instances.

Big data - Hadoop

Hadoop is a distributed, resilient big data framework that can manage petabytes of data. Its HDFS file system is scalable, and can be distributed across a high number of i1 nodes to deliver the very best performance during MapReduce operations.

Search engine - Elasticsearch

During its indexing phase, Elasticsearch requires a very quick response time for read/write operations. Furthermore, each search needs to deliver a quick response. i1 instances provide Elasticsearch with all of the power required for one of the most widely-used search services.

How to



Boot your instance, and choose the best model and operating system for you.



The NVMe drives are directly accessible as block devices. You can use them via system tools like a volume manager, or directly from the database engine.



Your instance is ready to deliver a high level of transactional performance.

Standard block storage access

Since NVMe drives are presented via PCI Passthrough, they appear as standard block storage devices, and can be used by your usual device management tools.

Guaranteed resources

Performance is guaranteed for each NVMe drive. The resources are not consumed by neighbouring instances under any circumstances.

IOPS billing

IOPS instances are billed like all of our other instances, on a pay-as-you-go basis at the end of each month. The price depends on the size of the instance you have booted, and the duration of its use.
