A new level of Storage Center OS efficiencySCOS 7 is a ground-breaking leap forward in the evolution of Dell’s SC platform, offering diverse environments the ideal access point to deploy uniquely adaptable, future-ready storage solutions. New capabilities include:
- Over 10:1 capacity savings with intelligent deduplication and compression*
- Federated data control with Live Migrate*
- Seamless business continuity with Live Volume auto-failover between arrays
- Unified management and cross-platform replication between SC and PS Series arrays*
- Quality-of-Service (QoS), VMware Virtual Volumes (VVols) support,* iSCSI Datacenter Bridging (DCB)* and more…
Key SC Series OS and software advantages are summarized below. See individual spec sheets and product documentation for additional features and specific platform support.
Self-optimizing, automated storageBased on actual use and application performance requirements, SC Series Data Progression automatically optimizes your drive tiers and RAID levels for performance and cost savings. By default, all new data is written to fastest Tier 1 drives at RAID 10 performance levels, then converted to economical RAID 5/6 for subsequent reads.
As data ages, it’s moved to less expensive storage until it becomes more active again. All-flash and hybrid arrays can leverage the unique attibutes of write- and read-intensive SSDs in combination. Data is precisely where it’s needed, when it’s needed – the perfect combination of high IOPs and cost savings.
Space savings in the data centerSC Series delivers unprecedented levels of platform efficiency, plus the most comprehensive data reduction.*
- Intelligent deduplication* and compression for all storage tiers and drive types
- Dynamic Capacity (thin provisioning) completely separates storage allocation from utilization, enabling you to allocate any size volume up front yet only consume physical capacity on write
- Data Instant Replays solves tradeoff issues between snapshot granularity and capacity cost savings
- Remote Instant Replay (“thin replication”) offers a cost-effective disaster recovery solution
Advanced data mobility, business continuity and securityThe SC Series Live Migrate “storage hypervisor” feature,* included with the base product, allows you to move data seamlessly between arrays without remapping your hosts, optimizing utilization of available capacity and cache across federated multi-array systems.
Live Volume auto-failover offers a native business continuity solution, providing volume-level protection from unplanned outages with no need for additional hardware or software.
And, to avoid data loss or compromise from physical security breaches, the SC Series offers a complete range of FIPS 140-2 certified self-encrypting drives (SEDs) in both SSD and HDD formats, plus support for leading third-party key managers.
Intuitive management at your fingertipsDell Storage Manager (DSM, formerly known as Enterprise Manager)* provides comprehensive monitoring and management of all local and remote SC Series arrays. With DSM you can streamline administration and reduce operating costs with advanced features like volume-level QoS, VVols support* and departmental “charge-back” reporting, allowing instant visibility and control of a multi-terabyte, multi-location environment.
DSM also allows you to perform day-to-day tasks across SC and PS Series arrays from a single management interface. Easy-to-use data replication and migration between platforms gives PS customers flexibility to add SC arrays to their environment, if and when they choose.*
Data center automation with leading technology partner integrationsSC Series features a vast array of integration points with VMware, Microsoft, Oracle, OpenStack, IBM, CommVault, Symantec, Foglight and more. VMware® vSphere™ plug-in, vCenter™ SRM adapter and VAAI support help you manage storage and virtual machines together.
With the introduction of Application Protection Manager for Oracle and now enhanced for the Linux environment,* you can create application-consistent Replays for Oracle databases. Combined with Storage Center Data Instant Replay (DIR), it will ensure reliable application, consistent backup and recovery of Oracle and Microsoft Volume Shadow Copy (VSS) enabled applications (Exchange, SQL and Hyper-V) and VMware virtual machines (VMs).
