StoneFly, Inc., a wholly owned business subsidiary of Dynamic Network Factory offers Unified Scale Out iSCSI + Scale out NAS storage appliances which fully support OpenStack software like Cinder, Swift and Glance. These appliances can not only be used as backend storage, but can also be used as a remote iSCSI boot device for diskless OpenStack nodes.
StoneFly iSCSI Storage Pool on the USO appliance can be used as a bootable iSCSI volume to implement diskless OpenStack nodes, as well as, diskless physical server nodes on demand. Users can rapidly and easily increase the quantity of Nova compute nodes or any other OpenStack nodes by adding diskless blade servers to their OpenStack cloud environment using StoneFly remote iSCSI boot.
Diskless OpenStack nodes will enjoy the numerous benefits of StoneFly iSCSI including delta based snapshots, mountable read-write snapshot volumes, thin provisioning, and real-time synchronous mirroring.
When it comes to encryption, the diskless OpenStack nodes will offer hardware enabled block level AES 256 volume encryption, optimized data deduplication, VSS support and asynchronous replication. Therefore, all these features definitely make StoneFly the advanced storage solution for any OpenStack environment.
For those users who use Cinder, a common limitation is often found where although volumes can be added to increase storage, those volumes cannot be expanded. StoneFly USO banishes these limitations as users can easily expand Cinder Block Storage Volumes by adding drives or additional StoneFly Scale out USS nodes. Since volumes can be easily expanded with multiple USO Scale out NAS appliance nodes, the volume for OpenStack will expand readily and expansion is nearly limitless.
Key advantages of using StoneFly USO for OpenStack shared storage and remote iSCSI boot:
- Since, StoneFly USO Unified Scale out iSCSI + Scale out NAS nodes feature hardware RAID, redundant hot swappable power supply modules, users will never loose access to their data if a compute node goes down.
- Reduces Capital Expenses and Operational Expenses since OpenStack nodes no longer need dedicated physical OS drives when using StoneFly remote iSCSI boot. Node reliability and availability increases since they are no longer at risk of disk failure.
- Cost-effective alternative to using local storage
- Makes it possible to share storage for other purposes beyond OpenStack (NAS or iSCSI storage for regular physical and virtual servers in your datacenter).
- Remote iSCSI boot allows OpenStack nodes to enjoy the built-in benefits of StoneFly iSCSI including snapshots and mirroring. Optional StoneFly iSCSI features such as data deduplication, encryption, asynchronous replication, and more provide for an even more feature-rich solution for diskless OpenStack nodes.
- Ability to scale/expand and increase the performance of a particular volume since you are not limited by the number of disks in a single physical machine.
- Management and recovery of compute nodes running Nova is much easier because you do not have to maintain their state. Since storage is not tied to another node, compute nodes can just be restarted as a new instance.
