The Chosen Solution
Hardware that used to power Usborne’s IT infrastructure caused some serious latency issues between the VM host and iSCSI storage servers. Their previous solution did not include any built-in failover option which, in the event of hardware failure or storage corruption, left them vulnerable. Broadberry all-flash, hyper-converged infrastructure turned out to be the best solution as it consolidated their entire infrastructure to just 2 nodes and 2 dual-port SAS JBODs with no single points of failure. As for the software, they have decided for the ZFS- and Linux-based Open-E JovianDSS configured as High Availability cluster which enabled consistent provision of datastores even in case one node crashes. What is more, Due to the fact that Broadberry storage is fully compatible with VMware’s API and thanks to the backup-focused On- & Off-site Data Protection feature in Open-E JovianDSS, Usborne IT administrators could easily revert to a previous state in a matter of minutes in the event of a ransomware attack or user error.
The On- & Off-site Data Protection feature allows users to back up and restore crucial company data in case of an unexpected disaster due to a combination of several technologies. This backupfocused feature enables creating consistent snapshots and asynchronous snapshot replication to local and/or remote destinations. The replication tasks can be set according to the specific user requirements thanks to advanced retention plans.
In order to solve Usborne’s latency issues, nodes were configured with dual Intel Xeon Gold 5120 Processors and 320GB of 2666MHz DDR4 ECC Registered memory to ensure the system can handle heavy workload. NAS appliances were configured with enterprise-grade SSD’s. At network level latency was omitted by using a dedicated point-to-point 10Gbe Interconnect between ESXI hosts, allowing more than enough throughput.
Benefits of solution by Broadberry and Open-E
The existing iSCSI storage was replaced with VMware ready ZFS network attached storage, consolidated within the VM host. Storage nodes run as VM’s eliminate the need for extra ones and the SSD-powered storage dramatically increased IOPS. Thanks to the ZFS- and Linux-based Open-E JovianDSS data storage software the customer could create consistent snapshots which could be stored locally. The software also provided full redundancy at both host and storage level, it was fully compatible with VMware API, plus, the thin-provisioned storage and compression by default enabled data reduction ration 2/1.
Moreover, the solution enabled online capacity expansion without need to initialize storage pool. Among the rest of benefits, it was worth to highlight also the automatic rebalancing option, read caching in RAM memory, 10GBe connectivity and also support for iSCSI, NFS, SMB and Fibre Channel. All in all, there’s been a significant increase of performance.
