Oracle Corp. today announced the general availability of its new Bare Metal Cloud Services, which the company is billing as the next generation of its Infrastructure-as-a-Service (IaaS).
The new IaaS product provides a “bare metal” cloud — servers with no Oracle software running on them — in a virtualized network environment that delivers high performance Database-as-a-Service (DBaaS), network block storage, object storage and VPN connectivity. The new services inter operate with existing Oracle Public Cloud services, and they can be provisioned on-demand, by console or API, with pay-for-what-you-use billing.
The Bare Metal services will be available initially in a new US-Southwest region in Phoenix consisting of three completely fault-independent Availability Domains that are physically separated from one another. A “region” is a localized geographic area; an Availability Domain is one or more datacenters located within each region. Because the domains are isolated from each other — they don’t share power for cooling, for example — they are less likely to fail simultaneously. The domains are connected by a high-bandwidth network that maintains a sub-millisecond latency across multiple domains in the region. A second region is due to come online in Ashburn, Va., in a few months, the company has said.
There are two types of bare metal DB Systems:
- 1-node DB Systems consist of a single bare metal server running Oracle Linux 6.8, with locally attached NVMe storage. This is the least expensive type of system and is recommended for test and development environments. If the node fails, you can simply launch another system and restore databases from current backups.
- 2-Node RAC DB Systems consist of two bare metal server running Oracle Linux 6.8, in a RAC configuration, with direct-attached shared storage. The cluster provides automatic failover. This system supports only Enterprise Edition – Extreme Performance and is recommended for production applications.
You can manage these systems by using the Console, API, Enterprise Manager, Enterprise Manager Express, SQL Developer, and the dbcli CLI.
Supported Database Editions and Versions
1- and 2-node RAC DB Systems support the following Oracle Database editions.
- Standard Edition
- Enterprise Edition
- Enterprise Edition – High Performance
- Enterprise Edition – Extreme Performance (required for 2-node RAC DB Systems)
The supported database versions are:
- Oracle Database 12c Release 2 (12.2)
- Oracle Database 12c Release 1 (12.1)
- Oracle Database 11g Release 2 (11.2)
When you launch a 1- or 2-node RAC DB System, you select a single Oracle Database Edition that applies to all the databases on that DB System. The selected edition cannot be changed. Each DB System can have multiple database homes, which can have multiple databases within them. All the databases within a database home will have the same version, but each home can have a different version.
Shapes for 1- and 2-Node RAC DB Systems
When you launch a DB System, you choose a shape, which determines the resources allocated to the DB System. The available shapes are:
- BM.HighIO1.36: Provides a 1-node DB System (one bare metal server), with up to 36 CPU cores, 512 GB memory, and four 3.2 TB locally attached NVMe drives (12.8 TB total) to the DB System.
- BM.DenseIO1.36: Provides a 1-node DB System (one bare metal server), with up to 36 CPU cores, 512 GB memory, and nine 3.2 TB locally attached NVMe drives (28.8 TB total) to the DB System.
- BM.RACLocalStorage1.72: Provides a 2-node RAC DB System (two bare metal servers), with up to 36 CPU cores on each node (72 total per cluster), 512 GB memory, direct attached shared storage with twenty 1.2 TB SSD drives (24 TB total).
The shape you choose for a DB System determines its total raw storage, but other options, like 2- or 3-way mirroring and the space allocated for data files, affect the amount of usable storage on the system. The following table shows how various configurations affect the usable storage for 1- and 2-node RAC DB Systems.
|Usable Storage with Normal Redundancy (2-way Mirroring)
|Usable Storage with High Redundancy (3-way Mirroring)
|12.8 TB NVMe
