IBM Cloud VMware Recommendations for SAN/NAS Appliances

QuantaStor storage servers provide VMware certified NFS and iSCSI storage with advanced features including encryption, compression, and remote-replication. iSCSI storage is also VMware VAAI integrated which greatly improves the performance of VM cloning and other network-intensive operations. QuantaStor storage servers for VMware include SSD to accelerate write performance and combined with a RAM-based read cache will deliver between 10K and 15K read/write IOPS (70/30). Automatic Snapshot Schedules with optional long term retention options make it easy to protect and recover data and virtual machines from previous points in time.

Compression usually improves usable capacity by 30% or higher for virtual machine workloads while also boosting performance. Remote-replication features allow replication to-from any QuantaStor appliances across IBM data centers and even to other locations to form a hybrid cloud Storage Grid. To ensure high availability in the event of a hardware outage it is recommended that one replicate VMware datastores to a second QuantaStor appliance in the same or remote IBM data center. Replication is block-level incremental, asynchronous, and may be configured to run at certain times of day or every few minutes to meet strong SLA requirements.

QuantaStor’s Storage Grid technology makes it easy to add storage appliances and manage all appliances through a single-pane-of-glass management interface which is built into the appliances. OSNEXUS QuantaStor is an available operating-system option on most server types and is available in all IBM Cloud datacenters worldwide. The QuantaStor license selection is a SaaS offering which includes access to all QuantaStor features with no additional feature add-on fees.
