dsmISI Virtual Machines (VMware)

Simplified integration of data stores and VMDK’s into Scale-Out NAS storage

With dsmISI for VMware, data stores and virtual machine disk files (VMDK) are automated and distributed symmetrically to all nodes of a PowerScale Scale-Out-NAS cluster. The solution is aimed at customers who want to use VMware efficiently with Dell PowerScale.

dsmISI VMware in detail

dsmISI for VMware enables organizations to integrate VMware and PowerScale (OneFS scale-out NAS) in an almost fully automated manner.
dsmISI ensures that maximum throughputs of PowerScale clusters are achieved when used as VMware datastores. At the same time, the software provides automated and easy-to-manage monitoring for capacity and performance
utilization. dsmISI for VMware uses VMware’s standard APIs to communicate with vCenter via PowerShell. Datastores and Virtual Machine Disk files (VMDK) are automatically distributed on PowerScale in such a way that a
symmetrical utilization of the nodes of a PowerScale cluster is guaranteed. In the event of a node expansion of the PowerScale cluster, this distribution is automatically adjusted with dsmISI for VMware in order to make optimal use
of the additional resources at all times.
With dsmISI for VMware, capacity distribution is generally based on throughput requirements. A classic, capacity-based distribution would be pointless, since in a PowerScale cluster the capacity across all nodes always represents
the sum of all capacities.
Rebooting an affected VM activates an updated distribution as needed. No data is physically moved during a re-configuration. It merely ensures that a VMDK is accessed via a different datastore/node.
Since PowerScale is a single distributed file system, all data is write and read active/active across all nodes at all times.
dsmISI for VMware also enables monitoring for performance utilization and capacity planning. Even in a large environment with thousands of VMDKs, petabytes of data and a correspondingly large number of PowerScale nodes, VMs and VMDKs, administration and monitoring thus remain simple, and the advantages of PowerScale’s unrivaled scalability remain manageable even with rapid expansion. Operating costs remain low.
dsmISI for VMware supports all applications that want to use a PowerScale environment in VMware. It is important to note that this solution makes most sense with applications generating a sequential workload, as PowerScale is less suitable for transaction-oriented access patterns (random workload).
In general, however, dsmISI for VMware is suitable for all applications prioritizing capacity and scalability over latency (e.g. backup applications such as Spectrum Protect Plus).
dsmISI for VMware supports protection against ransomware attacks based on PowerScale snapshots, which can be triggered application-consistently via dsmISI on PowerScale.
In addition, it is possible to store data worth protecting that is required for recovery with backup software (scripts, install images, documentation, etc.) on the PowerScale cluster and prevent manipulation using hardware snapshots.
This also lays the basis for copying such data to tape and/or other targets if necessary.
dsmISI for VMware thus offers the possibility to optimally use and easily manage scale-out NAS for VMware data-stores and as classic NAS storage.

dsmISI VMware Advantages and Benefits::

  • Easy integration of PowerScale scale-out NAS storage with VMware
  • Seamlessly grows from a few hundred terabytes to many dozens of petabytes
  • Automatically distributes VMDKs across datastores in seconds with no data movement at all
  • Maintains manageability – even with thousands of VMDKs
  • Reliably secures the entire environment against ransomware through non-manipulable integration of PowerScale hardware snapshots
