IBM FlashSystem V840

IBM FlashSystem™ V840 Enterprise Performance Solution merges IBM software-defined storage with the scalable performance of IBM FlashSystem storage to accelerate critical business applications and decrease data center costs simultaneously. IBM FlashSystem V840 software-defined flash accelerates critical business applications and through the use of Real-time Compression™ delivers flash for less than the cost of disk.

Drive new business opportunities with IBM FlashSystem V840

• Deliver flash storage for less than the cost of hard-disk drives (HDDs) with IBM® Real-time Compression™
• Preserve investments, centralize management and ease storage migrations with virtualization and IBM Easy Tier®
• Improve IT economics by integrating with existing infrastructure to reduce total cost of ownership and maximize return on investment
• Grow capacity and performance independently to match changing requirements
• Integrate with VMware using vStorage APIs for Array Integration (VAAI)
• Implement a full suite of storage services
• Use flexible deployment options to scale up, scale out, or scale up and out your storage infrastructure
• Boost reliability with enterprise-class flash storage and industry-leading storage virtualization technology
• Increase storage utilization by providing more flexible access to storage assets
• Improve administrator productivity by enabling centralized management of pooled storage from a single interface
• Offer scalable performance in storage devices that are both space and power efficient

Today’s storage capacity and performance requirements are growing faster than ever before—and the costs of managing this growth are eating up more and more of the typical IT budget. Flash storage can help address your performance requirements, while software-defined storage can help simplify data management, improve data security and preserve your investments in legacy storage. And now, flash technology and software-defined storage are available in one solution that provides flexible deployment architectures, extreme performance, simplified management and a fast return on investment (ROI). The market for all-flash arrays is saturated with products aiming to replace enterprise storage arrays but consistently failing to deliver the breadth of storage services delivered by incumbent solutions. Alternatively, hybrid arrays loaded with storage services consistently lack the low latency and performance scalability delivered by all-flash arrays.

Feature	Benefits
IBM MicroLatency	Delivers microsecond response time to accelerate critical applications and achieve competitive advantages
Enterprise reliability	Provides fully redundant, hot-swappable components; multiple RAID layers; AES-XTS 256 encryption; and concurrent code upgrades for maximizing uptime and availability
IBM Variable Stripe RAID technology	Maintains performance while enhancing reliability without sacrificing usable capacity
Superior flash media technology	Offers capacity coupled to performance via enterprise multi-level cell (eMLC) flash technology
Single point of control for storage resources	Designed to increase management efficiency Designed to help support business application availability
Pools the storage capacity of multiple storage systems on a storage area network (SAN)	Helps you manage storage as a resource to meet business requirements and not just as a set of boxes Helps administrators better deploy storage as required beyond traditional “SAN islands” Can help increase utilization of storage assets Insulates applications from physical changes to the storage infrastructure
IBM Real-time Compression	Increases effective capacity of storage systems up to five times, helping to lower costs, floor-space requirements, power and cooling May be used with a wide range of data, including active primary data, for dramatic savings
Easy-to-use IBM Storwize family management interface	Single interface for storage configuration, management and service tasks, regardless of storage vendor Helps administrators use their existing storage assets more efficiently
Dynamic data migration	Migrate data among devices without taking applications using that data offline Manage and scale storage capacity without disrupting applications
Managed tiered storage	Helps balance performance needs against infrastructure costs in a tiered storage environment
Advanced network-based copy services	Copy data across multiple storage systems with IBM FlashCopy Copy data across metropolitan and global distances as needed to create high-availability storage solutions
Thin provisioning and “snapshot” replication	Dramatically reduce physical storage requirements by using physical storage only when data changes Improve storage administrator productivity through automated on-demand storage provisioning
