Eon Mode volume configuration defaults for GCP
Vertica supports a variety of disk volume resources for provisioning instances on Google Cloud Platform (GCP).
All data is secured with Google-managed data encryption. Management Console does not support user-managed data encryption.
For performance information, see Google's Block storage performance documentation.
Persistent disk defaults
You can allocate up to 128 persistent disks (PDs). The following table describes the default persistent disk volume resources that Vertica provides:
Instance Types | Catalog | Depot | Temp |
---|---|---|---|
n1-standard/highmem-16 n1-standard/highmem-32 n1-standard/highmem-64 n2-standard/highmem-16 n2-standard/highmem-32 n2-standard/highmem-48 n2-standard/highmem-64 |
Configurable 1 PD (Standard/SSD) volume Default: 50 GB |
Configurable 8 PD (Standard/SSD) volume Default: 600 GB |
Configurable 1 PD (Standard/SSD) volume Default: 100 GB |
Local SSD defaults (ephemeral storage)
Allocate up to 24 local SSDs for ephemeral storage with the following considerations:
-
There is an extra cost for each local SSD.
-
All local SSD are 375G fixed size, with the option of SCSI or NVMe interface. An NVMe disk has twice the input/output operations per second (IOPs) compared to a SCSI disk.
Important
When the local SSD is in use, you cannot stop or start the instance or a cluster containing local SSD instances. If you do shut down an instance with a local SSD through the guest operating system, you will not be able to restart the instance and the data on the local SSD will be lost.
For details, see Google's Adding Local SSDs page.
The following table describes the default local SSD disk volume resources that Vertica provides:
