Your storage strategy is critical to long-term business success

Storage is the foundation that supports your applications, workloads and IT environments. Whether on-premises, in the cloud or in a hybrid environment, your data must be secure and available for fast analysis and processing. Downtime, network latency, under-utilization of storage resources – these issues not only waste time and frustrate teams but also directly affect your bottom line. As such, your storage strategy is critical to long-term business success.

To meet modern digital demands, your storage solution should reduce IT complexity, provide fast and reliable data access, improve security and streamline data mobility across multiple environments.

This is where flash storage comes in. Flash is valued for its performance and cost efficiency as well as its versatility in meeting a wide range of requirements.

In this guide, we’ll cover the benefits of flash storage and key capabilities to look for in a solution intended for modern hybrid cloud storage environments.

Flash storage is a solid-state technology that uses flash memory chips for writing and storing data. As indicated by its name, flash memory can achieve very fast response times (microsecond latency), compared to hard drives with moving components. It uses non-volatile memory, which means that data is not lost when the power is turned off. Flash storage is highly available and uses less energy and physical space than mechanical disk storage.

There are a variety of flash solutions on the market today designed to fit every size of business and budget, from entry-level to enterprise. But managing storage for a modern business environment involves more than just hardware. In fact, strategic storage choices are often more about the software foundation you select.

Look for a software-defined flash solution with an open, end-to-end architecture that can be deployed in any environment. This flexibility will help you modernize today’s workloads and save time and money by reducing complexity of management, monitoring and virtualization.

Flash storage solutions offer a wide range of enterprise-grade features, protocols and data services that match and often surpass those of disk-based offerings. Some of the most often cited benefits of flash storage include high throughput, data center efficiency and the ability to increase usable capacity while significantly improving application performance.

Let’s explore a few of the top reasons why flash is increasingly considered to be the new storage standard:

High performance

Users need faster data access, the business needs top speeds for critical workloads, and your infrastructure needs to effectively manage increasing volumes of data. Flash storage addresses these challenges with ultra-low latency and high throughput. It can respond in microseconds to deliver data quickly and efficiently for faster decision making. The high speeds of flash storage, combined with end-to-end NVMe and Storage Class Memory (SCM) technology, provide the power to quickly mine deeper insights and respond to requests almost instantaneously —all while using fewer resources than disk-based arrays.

Application agility

To accelerate innovation and growth for the business, you need to deploy applications and data where they make sense. Modern flash storage solutions improve data mobility and scalability while maintaining continuous data access and provide a consistent experience across containerized and hybrid cloud deployments. Save money by choosing a storage solution with right-sized products for your workloads and near-term strategy goals. The solution should also deliveragility to help you easily manage data scalability needs and changing application demands.

Data resilience

In today’s world of relentless cyberattacks, you need to make sure your data is always available, encrypted and tamper-proof – on-premises or in the cloud – and that your organization complies with all data privacy and protection requirements. Look for flash solutions that support system-wide FIPS-140 encryption, securing data wherever it resides without affecting performance.

Resource efficiency

Flash storage technology is very dense, endurant and requires less space than most disk-based solutions to store the same amount of data, so you can deliver more work with fewer drives and lower cost. When you invest in flash, you can save money by cutting back on costs associated with additional space and management requirements. And because flash memory modules use fewer resources than hard drives, they incur lower energy expenses.

Data efficiency

Look for a flash solution with data reduction technologies, such as pattern removal, deduplication and compression. Thin provisioning and space-efficient snapshots are additional functions that make the most of your storage capacity. The first compression cycle should work well enough so a second one won’t be needed. With the right storage software foundation, you can extend data reduction across all your heterogeneous storage, old and new, to store more data on the storage you already own without impacting performance.

Flexible acquisition

Limited budgets and ongoing pressures to optimize resources make cost a major factor in a storage strategy. Many vendors offer leasing and other flexible financing options to extend your budget, but don’t overlook additional consumption models including utility and as-a-service options when you’re evaluating how to get the most from your investment in flash storage solutions.

Overall, you’ll reduce complexity and increase efficiency by choosing a software-defined flash storage solution that enables you to consistently manage and optimize heterogenous storage resources across a wide range of deployment models including on-premises, hybrid cloud, containerized or virtualized environments.

Supporting capabilities include:

Icon cloud behind connected storage devices

Storage virtualization

Storage virtualization software centralizes management of storage resources across mixed environments, helping you uncover hidden capacity and increase data mobility. Look for solutions that extend data services – such as compression, deduplication, encryption, data reduction, and synchronous and asynchronous replication – to your existing storage whether those systems natively support them or not.

Data availability

Software-defined flash storage makesit easy to back data up to the cloud, providing disaster recovery and business continuity. Look for systems that offercyber security data services – such as multi-site replication with instant recovery, tamper-proof immutablecopies, copy data management, encryption – to ensure you’re set up to recovery quickly in the event of human error, system failure, or cyberattack.

End-to-end NVMe

NVMe is well suited for real-time applications and analytics because it can pull information from multiple sources in microseconds. Its high speeds improve throughput by reducing I/O overhead between CPUs and storage while eliminating storage-related infrastructure bottlenecks. NVMe also saves computing resources and IT expenses by supporting larger workloads.

Predictive analytics and performance monitoring

Intelligent storage monitoring provides visibility across your entire storage environment and helps you make more informed decisions around system optimization. Platforms with predictive analytics can improve capacity planning and storage utilization as well as provide proactive alerts to preempt future service disruptions, helping you troubleshoot issues more quickly.

Storage for containers

In a container environment, the data behind applications and microservices needs to be persistent with consistent performance and able to respond to rapid workload shifts. The underlying storage infrastructure you choose should unify traditional and container workloads, provide data resiliency features, and be open and agile to support modern workloads, cloud-native applications and public cloud integration.
