The Dell XC series are hyper-converged appliances using a combination of Nutanix software with Dell hardware. Dell servers are used along with the Nutanix Distributed File System which runs in a Controller Virtual Machine (CVM) in each node. Each scale-out cluster is comprised of a minimum of three nodes and has no specified maximum. Hypervisor options include VMware, Hyper-V or KVM.
Nutanix appliances have multiple-node configurations, either 1, 2 or 4 nodes per chassis. Here, the Dell XC series is different, with each appliance model supporting a single-server node, except the XC 6320, which has 4 nodes per chassis. All models come in hybrid or all-flash configurations.
Dell also offers a ‘storage-only’ node, enabling the cluster to scale capacity without adding compute resources and a 3U, single- node, quad-CPU model based on the Dell R940 server that’s designed for memory- and CPU-intensive workloads. The following list shows maximum resource capacities per node:
XC 430-4 – 1U, R430, single/dual CPU server, 14/28 cores, 384GB memory, 12TB HDD capacity, 3.2TB SSD capacity
XC 630-10 – 1U, R630 dual-CPU server, 32 cores, 768GB memory, 16TB HDD capacity, 3.2TB SSD capacity, 16TB SSD (in all-flash configuration)
XC 6320-6 – 2U, 4-node chassis, C6320 dual-CPU server, 24 cores, 512GB memory, 32TB HDD capacity, up to 38.4TB SSD capacity (in all-flash configuration)
XC 730-16G – 2U, single-node, R730 dual-CPU server, 32 cores, 768GB memory, 40TB HDD capacity, 6.4TB SSD capacity
XC 730xd-12C – 2U, single node, R730xd single-CPU server, storage-only node with 40TB of HDD capacity, 800GB SSD capacity. This model only supports the KVM hypervisor.
XC 730xd-12/24 – 2U, R730xd dual-CPU server, 12 or 24 drives, up to 32 cores, 768GB memory, 40TB HDD capacity, 6.4TB SSD capacity
