Guiding Principle 1: Identify priority applications and workloads to maximize immediate investment returns B U S I N E S S C H A L L E N G E : IT organizations often lack the proper tools and methodologies to effectively evaluate application requirements and develop well-informed data migration strategies.
When formulating a migration strategy it is important to identify and prioritize the applications that will benefit most from the new technology. All-flash storage arrays deliver breakthrough read/write speeds with ultra-low latency. They are ideal for data-intensive, delay-sensitive applications like analytics, virtual desktop infrastructure (VDI) and online transaction processing (OLTP). All-flash arrays also deliver extremely high availability and are well suited for business-critical applications and workloads. There are several aspects to optimizing the adoption of all-flash in the data center. A first step is establishing criteria for setting the migration priorities. Critical aspects include expected short-term returns relative to the effort and risk levels of the transformation. This cascades to development of a phased implementation plan. Typically business and operations teams collaborate to identify and rank applications hampered by performance or reliability constraints of disk-based storage systems. There is also an opportunity to reduce storage requirements. This requires one-time methods and procedures that can discover infrequently accessed data. Once identified, such data can be purged or moved to a supplemental storage tier as part of the transition. The criteria, ranking and collaboration work together to eliminate guesswork and consciously align data value with storage costs.

The conversion to high-speed flash storage can strain existing infrastructure. Organizations can minimize such risks by deploying automated discovery tools to examine the existing infrastructure environment (compute, storage and storage networking) for load scenarios that can negatively impact performance. HPE Pointnext recommends evaluating the architecture to identify changes needed to support the all-flash implementation (i.e. higher-capacity switches). A smooth journey to an environment optimized for all-flash often requires close collaboration between business teams and operations, InfoSec and networking groups. Checklist: 1. Work with business and operations teams to create a prioritized list of applications and corresponding data to transition to the new all-flash infrastructure. 2. Use automated discovery tools to gain visibility into the performance and utilization characteristics of existing applications and IT infrastructure, and identify remediation requirements. 3. Upgrade IT infrastructure, update administrative practices, and coordinate and communicate activities to ensure a graceful transition to the new storage environment. Expected Results: • Well-informed migration strategy that tightly aligns storage investments with data value. • Prioritized roadmap to optimize performance and reliability for data-intensive and business-critical applications. • Data-driven plan to update existing IT infrastructure and practices.

Guiding Principle 2: Define the new storage environment and develop a phased data migration plan to ensure a successful outcome B U S I N E S S C H A L L E N G E : Transitioning from legacy storage solutions to futureproofed flash platforms requires thorough design and planning. Next-generation platforms must meet long-term performance and scalability requirements and fit with established administrative systems and practices.
A successful transition requires thorough design and planning. This starts with the workload and data priorities and performance risks gathered in the discovery phase (Principle 1). These factors get rolled into the specification for next-generation all-flash storage platforms. That starts from technical, functional and business requirements and is combined with a deep understanding of the capabilities of the new platform to produce architectural guidelines. Platform understanding is key to accurately addressing the long-term scalability, performance, reliability and supportability requirements. A complete picture depends on collaboration with other functional organizations. All contributors must be accounted for to ensure data center networking infrastructure, security solutions and administrative systems and processes are updated to support the new storage implementation. HPE Pointnext has seen that this frequently requires revising provisioning and support systems and workflows. For example, ensuring new storage platforms comply with corporate security policies and data privacy mandates.

As mentioned in Principle 1, a phased data migration plan will prioritize applications that benefit most from the new storage architecture. The plan should build in proof of concepts and pilots to define best practices and build confidence. Migration is often regarded as risky, so this reduces risk and removes uncertainty. Best practices include standardizing and automate the migration processes through cookbooks and scripting. Since this is a one-time migration, external specialists can simplify the process. Be sure to define success criteria and create a formal acceptance test plan. Well-designed plans usually specify that the transition executes in waves to minimize staffing impact and avoid business disruption. Checklist: 1. Engage business teams and functional organizations early and often to gain mindshare and support. 2. Design a new storage environment that satisfies long-term technical, business, operational and data security/privacy requirements. 3. Develop a phased data migration strategy that includes proof-of-concepts and pilots to ensure success. 4. Create cookbooks and scripts to streamline the transition. Expected Results • Future-proof all-flash storage architecture that delivers superior performance, reliability and economics. • Prioritized data migration plan that aligns with business requirements and minimizes disruption and risks. • Automated, validated tools and pilot-refined processes that accelerate full-scale transition.

Guiding Principle 3: Make the transition as simple and risk-free as possible. Minimize downtime and disruption, and avoid data loss B U S I N E S S C H A L L E N G E : Migrating data to a new storage platform can be a resource-intensive, time-consuming and error-prone proposition.
Migrating applications and data to any new storage platform can be a complex undertaking. Every customer environment and workload is unique. You may be able to migrate certain applications in real-time without disrupting service. Other applications may require planned downtime. Many IT organizations don’t have the experience and wherewithal to handle large-scale data migrations. They may not realize where risks commonly arise, and how they are addressed. A professional services organization can help you minimize risk and avoid budget overruns and schedule delays. Best-of-breed professional services organizations have the expertise to help you determine the best migration method for a particular application. They also have the tools and resources to oversee or execute the migration. The right migration method for a particular workload will depend on a number of factors including the host operating system, the physical location of the new storage platforms, and data center interconnect bandwidth and latency characteristics. Addressing these relies on information gathered in the discovery phase to frame the best migration tools and methodologies for each application. There are a wide variety of commercial and open-source data migration tools to satisfy your specific functional and budget requirements. HPE Pointnext has in-depth experience with tools and can assist with evaluation and selection.

Guiding Principle 4: Protect and manage data during and after migration B U S I N E S S C H A L L E N G E : The new implementation must comply with corporate security, data protection and data management policies, and with relevant government and industry regulations.
As part of acceptance, IT planners, InfoSec teams and compliance organizations must certify the new storage implementation is secure, efficient and compliant. For example, validating that the new implementation adheres to established security systems and practices. HPE Pointnext recommends the use of strong encryption to secure data in transit and data at rest throughout the migration process. Layered security measures are a best practice to rigorously safeguard applications and data against malware, ransomware and viruses. To improve governance, the new storage architecture should integrate seamlessly to corporate authentication, authorization and access control systems. To avoid unexpected data loss, scalable data backup or replication solutions for business continuity and disaster recovery will be needed. As part of planning, data protection solutions must be specified to meet the recovery point and recovery time objectives (RPOs/RTOs) for the applications you plan to migrate. HPE Pointnext recommends automated data management tools to optimize storage resources and improve economics. They can intelligently move infrequently accessed data to archival storage or cloud storage services to better align storage costs with data value.
