New options for running the Oracle Database on EC2 using SSD storage for your database. The I2 instances feature the latest generation of Intel Ivy Bridge processors - each virtual CPU (vCPU) is a hardware hyperthread from an Intel Xeon E5-2670 v2 (Ivy Bridge) processor. I2 instances are available in four sizes as listed in the table below.
Instance Type vCPUs ECU Rating Memory (GiB) Instance Storage SSD (GB) Note i2.xlarge 4 14 30.5 1 x 800 800 GB of SSD i2.2xlarge 8 27 61 2 x 800 1.6 TB of SSD i2.4xlarge 16 53 122 4 x 800 3.2 TB of SSD. hi.4xlarge with 2 TB of SSD was previously largest SSD instance type i2.8xlarge 32 104 244 8 x 800 6.4 TB of SSD
The i2.8xlarge instance size is capable of providing over 365,000 4 kilobyte (KB) random read IOPS and over 315,000 4 KB random write IOPS. Great for Oracle databases that have high IO requirements.
