Block Storage

Block storage offers a block-device to users by means of iSCSI in the form of a LUN. The user is then free to configure its own file system.

Block storage is suitable for applications where an own file system is required, such as databases. It is available in several performance variants.

The properties of this storage service are shown in the following table below.

Tier Name Application Performance
1 High performance

  • Database (Logs), RDS/SBC

  • VDI low latency

  • IOPS guarantee: 1.000 IOPS per TB. Max. 16.000 per LUN 1

  • IOPS limits: 1.500 IOPS per TB. Max. 24.000 per LUN 2

  • Latency: 5 ms 3

  • Size: Min 250 GB, max. 16 TB per LUN 4, 5, 6
2 Performance (Default)

  • Generic VM’s

  • App / Web services

  • IOPS guarantee: 250 IOPS per TB. Max. 4.000 per LUN 1

  • IOPS limits: 500 IOPS per TB. Max. 8.000 per LUN 2

  • Latency: 10 ms 3

  • Size: Min 250 GB, max. 16 TB per LUN 4, 5, 6
Note:

  1. IOPS – Maximum value at 65% read / 35% write with 8 KB block.

  2. Limit – Determined on the basis of fair use. At long lasting exceeding the fair use, Equinix reserves the right to set the warranty as the limit.

  3. Latency – From the same data center, average per 5 minutes within IOPS-guarantee.

  4. Size – Increases per 250 GB.

  5. GBs will be implemented in multiples of 1024.

  6. 1 TB = 1000 GB.

Purchase Units

Managed Block Storage has one unit of purchase, namely:

  • Block Storage <Tier name> in GB

The contracted amount is charged per month in advance.

Relations and Dependencies

Block storage can be provided only with a direct connection. If a user isn't present in the data center where the storage is located, additional connectivity is needed, that must be purchased separately, not being part of the Managed Storage service.
