Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Product overview

The Cisco UCS® S3260 Storage Server (Figure 1) is a modular, high-density, high-availability, dual-node storage- optimized server well suited for service providers, enterprises, and industry-specific environments. It provides dense, cost-effective storage to address your ever-growing data needs. Designed for a new class of data-intensive workloads, it is simple to deploy and excellent for applications for big data, data protection, software-defined storage environments, scale-out unstructured data repositories, media streaming, and content distribution.

The Cisco UCS S3260 server helps you achieve the highest levels of data availability and performance. With dual-node capability that is based on the 2nd Gen Intel® Xeon® Scalable processor, it features up to 1,080 TB of local storage in a compact 4-Rack-Unit (4RU) form factor. The drives can be configured with enterprise-class Redundant Array of Independent Disks (RAID) redundancy or with a pass-through Host Bus Adapter (HBA) controller. Network connectivity is provided with dual-port up to 40-Gbps nodes in each server, with expanded unified I/O capabilities for data migration between Network-Attached Storage (NAS) and SAN environments. This storage-optimized server comfortably fits in a standard 32-inch-depth rack, such as the Cisco® R 42610 Rack.

Product highlights

      Dual 2-socket server nodes based on 2nd Gen Intel Xeon Scalable processors with up to 48 cores per server node

      Up to 1.5 TB of DDR4 memory per M5 server node and up to 1 TB of Intel Optane DC Persistent Memory

      Support for high-performance Nonvolatile Memory Express (NVMe) and flash memory

      Massive 1,080-TB data storage capacity that easily scales to petabytes with Cisco UCS Manager software

      Policy-based storage management framework for zero-touch capacity on demand

      Dual-port 40-Gbps system I/O controllers with a Cisco UCS Virtual Interface Card 1300 platform embedded chip or PCIe-based system I/O controller for Quad Port 10/25G Cisco VIC 1455 or Dual Port 40/100G Cisco VIC 1495 or 3rd party PCIe adapters

      Unified I/O for Ethernet or Fibre Channel to existing NAS or SAN storage environments

      Support for Cisco bidirectional transceivers, with 40-Gbps connectivity over existing 10-Gbps cabling infrastructure

The Cisco UCS S3260 server uses a multigenerational modular server architecture (Figure 2) and employs Cisco’s blade technology expertise to increase investment protection, allowing you to upgrade the main system components (Figure 3) without the need to migrate data from one system to another.

Advanced storage management

Cisco Unified Computing System (Cisco UCS) management helps significantly reduce management and administration expenses by automating routine tasks to increase operational agility. Cisco UCS management provides enhanced storage management functions for the Cisco UCS S3260 and all Cisco UCS servers. Storage profiles give you flexibility in defining the number of storage disks and the roles and uses of these disks and other storage parameters. You can select and configure the disks to be used for storage by a virtual drive.

A logical collection of physical disks is called a disk group, and a disk group configuration policy defines the way that a disk group is created and configured. A disk group can be partitioned into virtual drives. Each virtual drive appears as an individual physical device to the operating system. The policy specifies the RAID level to be used for the disk group. It also specifies either manual or automatic selection of disks for the disk group and roles for the disks. This feature allows optimization of the storage resources without additional overhead and licensing costs.
