Key learnings from peers

Valuable Features

Microsoft Storage Spaces Direct offers outstanding caching and tiering capabilities, enhancing speed and performance. Its affordability, ease of installation, and hardware compatibility add to its appeal. Resiliency and no single point of failure ensure data integrity. Its storage-class memory caching and high availability optimize workload management. Built-in protection mechanisms like mirroring and parity safeguard against data loss, maintaining data integrity. Users highlight the significant performance leap, noting its speed compared to traditional storage solutions.
  • "Its technical support is excellent."
  • "We chose Microsoft due to its simplicity, affordability, reliability and performance."
  • "The flash ability, in terms of tiering and caching, is amazing."

Room for Improvement

Microsoft Storage Spaces Direct needs better documentation and management tools. Integration challenges with hardware and network issues, along with switch requirements, are prominent. Licensing clarity and complete API support are lacking. Its performance with NVMe and SATA SSDs needs enhancement, and users struggle with resource-optimizing configurations. Users express a need for improved Windows Admin Center stability and alert features. Enhanced online documentation, sizing tools, and support for shared clusters are also sought by users.
  • "It is difficult to get a hardware compatibility certification for the solution."
  • "The management tool within this solution could be improved."
  • "The reason why this product is not being widely accepted by the public is that it doesn't include intuitive streamline, which makes it far from complete."

ROI

Microsoft Storage Spaces Direct enabled users to save significantly on virtualization and storage costs, with some estimating savings around 30%. They manage storage internally now, avoiding high SAN support fees. Even as systems near end-of-life, the financial benefits are expected to continue growing, with a recovery period of two years. Though measuring exact returns is challenging, it consistently meets various operational needs and delivers valuable cost and time efficiencies over a projected span of six years.

Pricing

Microsoft Storage Spaces Direct offers a bundled feature within Windows Server with a one-off price, including free upgrades and no ongoing costs. While considered expensive by some due to data center licensing, it remains one of the more affordable solutions within its category. Users find it cost-effective, particularly when using Hyper-V over VMware. Pricing can be advantageous, with licenses available on a monthly or yearly basis, though Azure-specific implementations can incur additional hidden costs.
  • "The solution is expensive."
  • "Cost-wise the product is one of the more affordable within the category of products."
  • "With the data center licensing and everything that is connected to that, this solution is relatively costly."

Popular Use Cases

Microsoft Storage Spaces Direct is utilized to enhance traditional hybrid setups and optimize data expansion costs. It supports site recovery, consolidations like ACI and EDI, and SQL server operations. Users leverage it for hyper-converged infrastructure, critical storage, high IOPS needs, virtualization, and application-centric infrastructure. It functions as primary storage, accommodates internal disks, serves SQL Server operations, and integrates easily for Microsoft Cluster storage in system integration projects.

Service and Support

Technical support can be accessed from Microsoft or selected hardware brands like Dell and Lenovo. Although Dell and Lenovo handle solutions and support contracts directly, many feel Microsoft's frontline assistance lacks adequacy, especially for crucial business operations. Premium contracts are deemed valuable, allowing access to advanced support levels. Some users express dissatisfaction, noting a stronger focus on Azure. Ratings vary, with customer service often considered underwhelming and sometimes unable to resolve issues promptly.

Deployment

Microsoft Storage Spaces Direct's initial setup is generally straightforward but requires detailed knowledge of storage and network configurations. High-speed storage networks need precise tuning, and hardware specifics can complicate processes. Compatibility issues may arise, and varied hardware demands different requirements. Despite initial challenges, many find the setup easy, especially with command-line expertise or following available online guides. Documentation has improved since Server 2016's release, and step-by-step instructions aid implementation.

Scalability

Microsoft Storage Spaces Direct scales effectively, accommodating cluster expansion up to 16 nodes, with cluster set technology enabling further growth. Users appreciate its scalability with both vertical and horizontal expansion. Challenges arise when scaling from two nodes or migrating workloads after adding hosts, but overall they find the architecture advantageous. Some report limitations in scalability, potential latency issues, and initial redundancy problems, which were resolved with additional capacity and mirror configurations at both disk and server levels.

Stability

Microsoft Storage Spaces Direct is largely stable, especially when managed correctly, although initial setup may pose challenges. Users experienced stability issues initially but noted improvement with familiarity and proper configuration. Utilizing Storage Spaces Ready Nodes can enhance reliability. Adequate training for users is crucial. Stability is rated around seven to eight out of ten. Configurations must be correct to avoid unexpected issues for users. Small applications run smoothly on-premises.
