      2    Platforms for KumoScale Components

      KumoScale software is installed on servers external to the target storage or application initiator nodes. These components require additional servers, which may not be solely dedicated for this purpose.

      2.1           KumoScale Storage Cluster

      The KumoScale storage cluster is a High Availability (HA) cluster implemented over a private Kubernetes environment. The cluster requires at least three (3) servers for replication to ensure HA. The following sections specify the requirements for the servers used in this cluster and the network requirements.

      2.1.1          Hardware Requirements

      The following table specifies the minimal hardware requirements for the physical server components, and the recommended configuration according to the expected deployment’s scale (number of KumoScale storage nodes):

      Component

      Minimal Requirements

      Best Practice

      CPU

      4 cores

      <10 KS nodes – 4 cores

      10-100 KS nodes – 12 cores

      >100 KS nodes – 24 cores

      Memory

      16GB

      <10 KS nodes – 16 GB

      10-100 KS nodes – 32 GB

      >100 KS nodes – 128 GB

      Boot Drive

      40 GB

      <10 KS nodes – 40 GB

      10-100 KS nodes – 80 GB

      >100 KS nodes – 128 GB

      2.1.2          Topology

      Each server must be installed on a different rack to ensure HA.

      2.1.3          Network Requirements

      This section specifies the requirements for the server’s ports. These ports must be accessible by the orchestrator, KumoScale storage nodes, and application hosts.

      2.1.3.1   Management Ports

      Each of the servers should have at least two management ports. The table below specifies the bandwidth minimum value and recommendation according to the expected deployment’s scale (number of KumoScale storage nodes):

      Minimal Requirements

      Best Practice

      2x1 Gbps

      <10 KS nodes – 2x1 Gbps

      10-100 KS nodes – 2x10 Gbps

      >100 KS nodes – 2x25 Gbps

      2.1.3.2   Data Ports

      Each server requires a data port. The data and management ports may be combined on a single logical interface if there are at least two ports with a bandwidth of ≥ 25 Gbps each.

      2.1.4          Storage Requirements

      There are no storage requirements. KumoScale cluster management services require persistent storage but this is provisioned by KumoScale software NVMe-oF™ volumes, so no additional storage is required on the servers used for this cluster.

      2.2           Ansible Server

      In a bare-metal environment, an Ansible server is required for running the Ansible modules and playbooks (this can be the same server that is used for the storage cluster).

      The only requirement for this Linux OS-based server is to have connectivity with the KumoScale appliance management IP and the application hosts.

       

      [1] Definition of capacity - KIOXIA Corporation defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1Gbit = 230 bits = 1,073,741,824 bits, 1GB = 230 bytes = 1,073,741,824 bytes and 1TB = 240 bytes = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
