Overview

Cloud Avenue provides 2 types of storage:

  • Datastore type storage, for virtual disks of VMs (vmdk files)
  • Network storage, accessible via NFS or SMB

Datastore type storage is made available to VMs in a vDC through storage profiles, from which the VMs can draw to provision their disks. The size of a vmdk file is limited to 2 TB. When a VM must have storage greater than 2 TB, the vmdk files of the VM must be multiplied to reach the target size.

Datastore type storage is provided in two modes:

  • Shared datastore (by default),
  • Dedicated datastore, with guaranteed performance.

Shared Datastore

Service classes

For each vDC performance class, one or more storage performance classes can be associated; the compatibility matrix describes them in the following table:

Services classes Maximum IOPS Available for the vDC
Eco Standard High Performance VOIP
Silver 600 IOPS / TB
Gold 1000 IOPS / TB
Platinum 3K 3000 IOPS / TB
Platinum 7K 7000 IOPS / TB


Some classes of service are available in Dual Room to offer room choice, and in HA Dual Room on a storage Metro-cluster, spread over two rooms in Val de Rueil. The characteristics and availability of these classes of service are detailed in the following table:

Services classes Available for the vDC
One Room Dual Room HA Dual Room
Silver
Gold
Platinum 3K
Platinum 7K

Multiple storage profiles can be associated with a single virtual machine.

The IOPS resources are pooled between all the VMs using the Datastore on which the Customer deploys his VMs.

Billing

PAYG

The storage considered is the maximum space occupied during a day by:

  • each VM, including the space used by the VM and by the snapshot possibly made by the Customer
  • the Templates and ISO images present in the Client's private catalog

VM technical files like vmware swap file also consume space but are not charged.

The storage sizing of a vDC ordered by the Customer must take into account:

  • the virtual disks of the VMs that will be created in this vDC
  • VM RAM
  • possibly the space to take a snapshot.

Per subscription

The storage taken into account is the observed average storage allocated to the vDC during the reference month.

Dedicated Datastore

A storage policy, made up of one or more dedicated datastores, is made available to the Customer for their exclusive use. That is to say that only the VMs chosen by the Customer will be able to use this storage space, which allows him to make the best use of the number of IOPS available.

The maximum size of a Datastore is 10 TB, but a storage policy can have several Datastores, and can therefore reach very large sizes. Contact support for requirements above 30 TB.

A storage policy is attached to a single vDC.

Service classes

This type of storage is available, depending on the vDC classes:

  • In One Room
  • In Dual Room (choice of room possible)
  • In HA Dual Room (on a storage Metrocluster on both rooms)

Ordering a dedicated storage policy (dedicated datatore) is possible for all of the following classes of service:

Service classes Performance Minimum size Available for vDC
One Room Dual Room HA Dual Room
Silver 600 IOPS / To 8 To
Gold 1000 IOPS / To 6 To
Gold Metrocluster 1000 IOPS / To 6 To
Platinum 3K 3000 IOPS / To 4 To
Platinum 3K Metrocluster 3000 IOPS / To 4 To
Platinum 7K 7000 IOPS / To 4 To
Platinum 7K Metrocluster 7000 IOPS / To 4 To

À noter !
For a dedicated Datastore, the deduplication mechanisms embedded in the storage equipment benefit the Customer. That is to say, if the Customer deploys several VMs based on the same template, this will significantly increase the rate of deduplication, and consequently will limit the total amount of storage billed to the Customer.


Billing

The storage taken into account is the observed average storage reserved by the Customer during the reference month.

The quantity of IOPS actually provided corresponds to the volume of storage ordered times the number of IOPS/GB of the class of service subscribed.

Example:

4 TB of Platinum 7K storage can permanently use 28,000 IOPS, regardless of the number of VMs using this storage.

Network storage

External storage is made available to VMs via IP addresses and according to the protocols chosen by the Customer.

Network storage is always provided in dedicated mode.

Service classes

Service classes Maximum IOPS Availability
One Room Dual Room HA Dual Room
Silver 600 IOPS / To
Gold 1000 IOPS / To
Platinum 3K 3000 IOPS / To

The quantity of IOPS actually provided corresponds to the volume of storage ordered times the number of IOPS/GB of the class of service subscribed.

Example: 500 GB of Platinum 3K network storage permanently uses 1500 IOPS, regardless of the number of VMs using this storage.

Backup

The Customer can set up the "snapshot" policy for his network storage himself. The space used by the "snapshots" is deducted from the quota subscribed by the Customer. Depending on the chosen policy, the Customer must reserve for "snapshots" between 5 and 20% of the total amount of storage subscribed. However, you can activate the "snapshots" even without a reserved space

Management interface

A self-service portal is provided to Customer for network storage management. Using the Portal, Customer can:

  • Adjust the quotas of its shares
  • Set rights, manage the list of VMs (NFS) or users (CIFS) with access to a share
  • Restore all or part of a backup "snapshot" (copy files from a guest VM)
