StretchHA Storage Solutions
Enterprise-grade StretchHA storage designed for continuous operations, scalable resilience, and long-term confidence across sites and locations.
Holstein IT–Solutions delivers StretchHA storage architectures that scale from a single rack to multi-site, geographically distributed environments. Whether deployed within a rack, across buildings, or between distant locations, StretchHA provides consistent data access, predictable behavior, and operational clarity—built on open technologies and delivered by experts.
Two Ways to Deploy StretchHA
Whether you prefer hardware flexibility or a fully integrated system, Holstein IT–Solutions offers StretchHA in two clear,
enterprise-ready models.
Choose the approach that best fits your infrastructure strategy, procurement model, and internal capabilities.
Option 1: Holstein IT-Solutions Storage Solution (Complete Stack)
Holstein IT–Solutions Certified Hardware + Software + Consulting
A fully integrated StretchHA storage platform designed, delivered, and supported by Holstein IT–Solutions—ready for mission-critical
workloads from day one.

Option 2: Bring Your Own Device (BuyYOD)
StretchHA Storage Software + Expert Configuration
A complete StretchHA storage solution that allows organizations to use their preferred or existing hardware vendors, while Holstein IT– Solutions delivers the software, validated architecture, and deployment expertise required for a production-grade StretchHA environment.
This option is ideal for teams that want enterprise resilience without changing hardware suppliers or being locked into a single vendor.
What’s included:
• StretchHA software stack
• JBOD-based expansion support
• Architecture design, validation, and best practices
• Professional installation and configuration by Holstein IT–Solutions engineers (optional)
Note: Storage can be deployed using a single JBoD or expanded over time. There is no fixed storage limit.
Why organizations choose BuyYOD:
• Protects existing vendor relationships
Continue working with your preferred hardware and SSD suppliers without disruption.
• Hardware independence with enterprise-grade reliability
Choose SSDs and components from the compatibility list without purchasing hardware from Holstein IT–Solutions
• Proven in production
Built on real-world deployments with strong references and operational credibility.
• Predictable failover and operational clarity
Designed for controlled behavior during failures, upgrades, and day-to-day operations.
What Is StretchHA?
StretchHA is a storage architecture that synchronously mirrors data across locations, enabling continuous operations and consistent data access—whether deployed within a site or across geographically separated environments.
Key capabilities:
High availability within a single rack or chassis
Resilience across racks and buildings
StretchHA operation across firewalls and network boundaries
Geographic deployment across sites and locations
Active-active option for simultaneous multi-site operation
Designed RPO/RTO aligned with business needs
When StretchHA Is the Right Choice
StretchHA is designed for organizations that need uninterrupted access to their data, no matter where it’s stored. It’s perfect for teams that:
• Operate mission-critical or regulated workloads
• Require predictable recovery and continuous availability
• Need replication across racks, buildings, or sites
• Want zero single points of failure
Common use cases include:
• Disaster recovery and business continuity
• Multi-site production environments
• Critical databases and virtualization platforms

Choosing the Right Storage Configuration
Storage requirements change as organizations grow, expand geographically, and take on more critical workloads. The right storage architecture should support today’s needs while allowing flexibility for tomorrow—without forcing disruptive redesigns.
Use the following considerations to determine the most suitable StretchHA configuration for your environment.
Availability Requirements
Define the level of availability your workloads require today and how that may evolve over time.
– What degree of operational continuity is required for your applications?
– Are you planning for higher availability as systems become more critical?
– Should resilience be limited to a single rack, extended across buildings, or designed for multiple sites?
Geographic Distribution
Geographic distribution is not just a technical feature—it is a business decision and a core part of a long-term recovery strategy.
– Do you need to actively distribute data across buildings or sites to support operations?
– Is geographic separation part of your business continuity or recovery plan?
– Will future expansion require data to be available closer to users or services in different locations?
Performance Needs
Ensure your storage platform can meet current performance demands while scaling with future workloads.
– What are your peak IOPS, throughput, and latency requirements?
– Are performance needs expected to grow as applications, users, or data volumes increase?
Budget & Growth
Balance initial investment with future scalability and expansion requirements.
– What is your starting capacity requirement?
– How much growth do you expect over the next three to five years?
– What is your tolerance for incremental expansion versus large upfront investments?
