Transitioning to All-Flash Storage
For many organizations considering a storage refresh today the key reasons to transition to all-flash storage include the opportunity to accelerate all current applications rather than a select few, and to gain performance headroom to add more applications and handle growing amounts data.
Another factor driving AFA adoption is simplification, including the ability to integrate with automation frameworks via REST API support and with hypervisor management consoles.

Consolidation and Simplification are Keys to Creating Business Value
Consolidating many workloads onto an all-flash array can enable significant reductions in overall data center costs. AFA-enabled consolidation extends beyond storage consolidation to include server and even data center consolidation.
Since the current generation of all-flash arrays have the capacity and performance to potentially handle many workloads concurrently, features that enable consolidation are a reasonable focus for evaluation.
Features that Enable Consolidation
- Sufficient storage capacity
- Storage density much higher than the density of the legacy storage system
- Performance – Latency, IOPS, Bandwidth
- Multi-protocol (unified SAN and NAS) support
- High-speed Fibre Channel (FC) and Ethernet connectivity to application servers
- Quality of Service features (QoS)
- Non-disruptive Upgrades (NDU) & redundancy features that maximize uptime availability.
- Certified support for Enterprise Applications
Features that enable simplification can significantly improve IT agility, and therefore also deserve careful consideration.
Features that Enable Simplification
- Automated intelligent caching and/or storage tiering
- Automated/policy-based provisioning
- Hypervisor management console integration empowering administrators to quickly allocate and assign storage to new virtual machines
- Proactive intervention based on storage analytics
- Proactive remediation based on fault data
- QoS based on predefined service levels enabling an administrator to quickly and easily assign each application or volume to a priority classification
- REST API to enable integration into automation frameworks that are the foundation for self-service ITaaS
There are staffing and organizational implications associated with consolidating and simplifying storage. These will need to be addressed if an organization is to derive full value from its all-flash transition.

Capacity and Density
Average AFA flash density of the products assessed in the Buyer’s Guide is 80 TB/RU with some arrays achieving 192 TB/RU. The combination of all-flash performance and high storage density means that an AFA may be able to meet an organization’s performance and capacity requirements in 1/10th the space of legacy storage systems, creating an opportunity to realize significant data center cost reductions.

Quality of Service (QoS)
Managing storage performance can be complicated. The raw performance of an AFA may initially enable it to service all applications adequately. However, if enough applications are consolidated on the AFA, contention for finite resources will inevitably surface. Quality of service (QoS) features enable confident consolidation by ensuring critical applications receive appropriate performance resources. Most AFAs now support QoS features. The simpler these are to implement, the better.
Management Integration and Automation
Workflow automation is increasingly important as enterprises strive to streamline their business processes. Storage vendors understand this challenge and are continually adding management flexibility to the arrays. By supporting multiple management interfaces, AFA’s can be deployed more quickly and incorporated into existing workflows. VMware vCenter is universally supported. Management integrations with Microsoft and open standards are now widely supported.
