Rymvard released version 0.23 on Oct. 4, 2026, adding SAP HANA capacity planning for hosting providers and SAP operations teams. The release tracks HANA memory use and availability, checks whether replication sites can take over workloads, and helps plan new placements, addressing memory as a resource that can constrain HANA hosts.
The software breaks down each HANA host’s physical memory into an operating-system reserve, memory used by each system, allocated but unused memory, capacity held for replicas at other sites, and memory that is actually free. Rymvard says a system’s memory use is measured using its 30-day peak. Its default operating-system reserve is 10 percent of the first 64 GiB and 3 percent of the remaining memory, unless a host specifies its own reserve. Allocations exceeding physical capacity appear as overbooking, rather than being masked as negative free memory.
For systems using HANA system replication, Rymvard assesses whether a secondary host could accommodate the primary system’s allocation after takeover. The calculation allows test and development systems on the secondary to be stopped, but does not count production systems belonging to other customers as stoppable. Results are categorized as fitting, fitting after named systems stop, not fitting with a shortfall in GiB, or unknown. A replication status older than one hour or a memory reading older than 24 hours makes the assessment unknown. Scale-out systems are assessed across the full system, based on the weakest host pair.
Rymvard also proposes a host for a new HANA system and a partner host at the replication site. Planned go-lives can be weighted by probability to estimate a memory runway by site and quarter. HANA instances are added to Rymvard’s compute view for customer showback and lifecycle planning. A new SAP Operations workspace presents free HANA memory, production systems without replication, takeovers that would fail, and HANA hosts above 90 percent utilization.

Rymvard Brings SAP HANA Capacity Planning to Hosting Providers
An early access release gives hosting providers and SAP operations teams a view of HANA memory headroom, replication takeovers, and future placements across sites.
01 / Memory accounting
See where host memory goes
Rymvard separates physical memory into clear categories, exposing both usable headroom and commitments that might otherwise be hidden.
Operating system
Default reserve: 10% of the first 64 GiB, then 3% of remaining memory. Hosts can set a custom reserve.
System memory
Each HANA system is measured using its 30-day peak memory use.
Unused allocation
Capacity assigned to systems but not currently consumed remains visible.
Replica capacity
Memory held for replica systems at other sites is included in the plan.
Free memory
Remaining physical capacity appears as free. Excess allocation is shown as overbooking.
When allocations exceed physical capacity, the view flags overbooking instead of disguising it as negative free memory.
Planned go-lives can be weighted by probability to estimate future memory headroom.
02 / Replication readiness
Check whether a takeover can fit
For HANA system replication, Rymvard tests whether a secondary host can accommodate the primary system’s allocation after takeover.
What the calculation allows
The pair’s own replica is replaced. Test and development systems on the secondary may be stopped to make room. Production systems belonging to other customers are never counted as stoppable.
What the result says
Scale-out landscapes are assessed across the full system, using the weakest host pair. A stale input does not count as proof that a takeover will work.
Read status
Check replication state and memory data freshness.
Model capacity
Compare the primary allocation with secondary headroom.
Apply stop rules
Allow eligible test and development systems to stop.
Report fit
Show fit, conditional fit, shortfall, or unknown.
03 / Placement & operations
Plan the next system, then track the estate
The release extends capacity planning into placements, showback, and an operations workspace for teams managing HANA across customer environments.
Operations workspace signals
Workspace highlights free HANA memory, production systems without replication, takeovers that would fail, and hosts above 90% utilization.
HANA instances are added to Rymvard’s compute view for customer showback and lifecycle planning.
Assessments and forecasts depend on connected data quality, freshness, and how providers use the results.
04 / Access model
Company-described read-only connections
Rymvard says its product reads SAP data through bounded interfaces and does not write to SAP. These are company descriptions, not an independent security assessment.
Four permitted operations
ListInstances, ListDatabases, GetDatabaseStatus, and GetComputerSystem. The collector is said to reject other operations.
Fixed query limits
Six fixed SELECT queries, a 60-second limit per system, and no more than eight systems queried at once using a monitoring user.

05 / Evidence & availability
Early access, with customer results still pending
Rymvard reports a simulated landscape test. The company says the figures are not customer operating data and example screens show an illustrative estate.
The simulation also identified one production system without replication, one host overbooked by 128 GiB, and one replication in an error state. Rymvard has not provided customer deployment results, independent testing, measured operational outcomes, or a broader launch date. Pricing is negotiated with early access partners.
Rymvard says the software is running and available through its early access program. Providers can contact the company to discuss participation. The next useful evidence will come from live connections and comparisons between assessments and day-to-day operations.
Planning HANA Capacity Across Sites
Hosting providers need to allocate memory among customer workloads while accounting for replication, reserves and systems that are not currently using all their allocated capacity. Rymvard’s release brings those categories into a single capacity view and makes the assumptions behind takeover planning visible, including which non-production systems could be stopped to free space.
The distinction between a failed fit and an unknown result matters operationally: stale replication or memory data is not presented as evidence that a takeover will work. The tool’s planned-go-live forecasts could also help teams see how expected deployments affect future headroom, although the release information does not establish how accurate those forecasts are in customer environments.
Rymvard says HANA instances are reflected in its wider compute view, linking SAP memory capacity with customer showback and lifecycle planning. That may help providers incorporate SAP workloads into broader infrastructure decisions rather than treating them as a separate accounting exercise. The practical effect will depend on the quality and freshness of connected data and how providers use the resulting assessments.

Read-Only SAP Data Connections
Rymvard says the product connects to SAP on a read-only basis. A collector at each site communicates with SAP Host Agent over HTTPS and permits four operations: ListInstances, ListDatabases, GetDatabaseStatus and GetComputerSystem. The company says the collector rejects other operations. A separate data path queries HANA monitoring views through a monitoring user over TLS, using six fixed SELECT queries, with a 60-second limit per system and no more than eight systems queried at once.
For system, customer and environment information, the product can read from SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa, using their read-only interfaces. Rymvard says it does not write to SAP. These design details describe the company’s stated access model; they do not amount to an independent security assessment.
The company reports testing the software against a simulated landscape containing 200 HANA hosts, 161 systems and 39 replicated pairs. In that test, it identified one production system without replication, one takeover that would not fit by 512 GiB, one host overbooked by 128 GiB, and one replication in an error state. Rymvard describes the figures as results from a simulation, not customer operating data. It says the product is in early access, and that displayed screens use an illustrative example estate rather than a customer environment.

Early Access, No Customer Results
The release is in early access, and Rymvard has not provided customer deployment results, independent testing, or measured operational outcomes. The test figures come from a simulated landscape; the company says its example screens do not depict a customer estate. It remains unclear how the product performs across live, varied SAP environments or how often its capacity and takeover assessments change as data updates.
Rymvard has not published pricing, saying terms are agreed with early-access partners. The release information also does not specify which integrations are available to each partner, the rollout schedule beyond current early access, or what service and support arrangements are offered. Its stated read-only design and query limits are company descriptions, not a third-party security certification.

Early-Access Partner Rollout
Rymvard says the software is running and available through its early-access program. Interested providers can contact the company to discuss participation; pricing is negotiated with early-access partners rather than published publicly. The company has not announced a broader launch date or a timetable for moving out of early access.
The next useful evidence will be whether providers can connect their SAP landscape tools and HANA monitoring data successfully, and how the system’s capacity and takeover assessments compare with live operations. Rymvard has not announced customer deployments or independent validation, so those results remain pending.
