DataCore HCI-Flex Appliance is a hyperconverged infrastructure solution that combines DataCore’s software-defined storage (SDS) solution, SANsymphony, with Dell x86 servers. SANsymphony, is a storage virtualization product that DataCore originally developed a number of years ago and for which it has built an installed base of over 10,000 customers. The HCI-Flex appliance comes preinstalled with either Hyper-V or vSphere.
Configurations can scale from 2 to 64 server nodes managed from a single point to provide redundancy and increase capacity of the storage pool to over 1PB (raw). DataCore offers four models using the 1U Dell R640 server with dual Intel Xeon CPUs (up to 24 cores). These are the HCI-Flex 3 and HCI-Flex 5, which both come in hybrid and all-flash configurations with up to 8 SSDs or 6 HDDs. The HCI-Flex 7 runs on 2U Dell R740XL servers with dual Intel Xeon CPUs (44 cores) and comes in four models, with hybrid or all-flash configurations and up to 16 SSDs or 11 HDDs.
The parallel IO architecture of the SANsymphony SDS layer enables the HCI-Flex Appliance’s storage performance to keep up with the compute performance available in a cluster of multi-core servers. Combined with automated storage tiering and DRAM caching, the HCI-Flex Appliance produces some of the best performance of HCI products currently on the market.
DataCore’s HCI-Flex Appliance can connect to external storage arrays via iSCSI or FC and present these volumes to VMs running on it. External servers can also connect to the shared storage pool. This enables the HCI cluster to expand storage or compute capacity without adding more nodes. Based on the mature SANsymphony software, the HCI-Flex Appliance offers an extensive list of data services and features, including: auto-tiering, load balancing, QoS, continuous data protection, synchronous mirroring, data migration, AES-256-bit encryption, VVOL integration and asynchronous replication to the public cloud.
