Overview
The durability of data stored on a local disk depends on the reliability of the associated physical machine. A single point of failure (SPOF) risk exists. Data stored on local disks may be lost. Store only temporary data on local disks. For more information, see Local disks.
Instances equipped with local SSDs deliver high I/O performance. They suit scenarios that demand high storage I/O performance and require high availability at the application layer, such as NoSQL databases, massively parallel processing (MPP) data warehouses, and distributed file systems.
These instances also suit enterprises that run online services such as gaming, e-commerce, live video streaming, and media. They meet the low-latency, high-IOPS requirements of I/O-intensive applications for block storage devices.
Instances equipped with local SSDs have the following characteristics:
Deliver up to hundreds of thousands of low-latency random read/write IOPS for large databases.
Offer a maximum sequential read/write throughput of several gibibytes per second in big data, parallel computing, and other large dataset scenarios.
Use local Non-Volatile Memory Express (NVMe) SSDs to deliver hundreds of thousands of random read/write IOPS with single-digit microsecond latency.
When you use instances equipped with local SSDs, take note of the following items:
Instances equipped with local SSDs do not support instance configuration changes.
Local disks are tied to specific instance types. The number and capacity of local disks attached to an instance vary based on the instance type. You cannot separately purchase local disks, or detach local disks from instances and then attach the disks to other instances.
You cannot create snapshots for local disks. To create an image from the system disk and data disks of an instance equipped with local SSDs, create an image by combining the snapshots of both the system disk and data disks. In this case, the data disks must be cloud disks.
You cannot create images that consist of system disk snapshots and data disk snapshots based on instances equipped with local SSDs.
You can attach a standard SSD to an instance equipped with local SSDs and extend the capacity of the standard SSD.
Operations on an instance equipped with local SSDs may affect the data stored on the local SSDs. For more information, see the Impacts of instance operations on data stored on local disks section of the "Local disks" topic.

i2, instance family with local SSDs
This instance family provides high-performance local NVMe SSDs with high IOPS, high throughput, and low latency.
Use cases: OLTP and high-performance relational databases, NoSQL databases such as Cassandra, MongoDB, and HBase, and search scenarios that use solutions such as Elasticsearch.
Compute:
vCPU-to-memory ratio of 1:8, designed for high-performance databases.
Powered by 2.5 GHz Intel Xeon Platinum 8163 (Skylake) processors.
Storage:
All instances are I/O optimized.
Supports standard SSDs and ultra disks.
Network:
Supports IPv4 and IPv6. For more information, see IPv6 communication.
Network performance scales with instance type. Larger instance types provide higher network performance.
