Rymvard released early-access version 0.23 on October 4, 2026, adding SAP HANA host memory accounting, placement proposals and replication takeover checks to its data center capacity ledger. The company tested the release on a simulated estate and has not reported customer deployments or outcomes.
Rymvard released version 0.23 on October 4, adding SAP HANA memory accounting, system placement proposals and replication takeover checks to its data center capacity ledger. The early-access software is aimed at SAP hosting providers and operations teams, but the company’s reported tests used a simulated landscape, not a customer deployment.
The ledger divides each HANA host’s physical memory into an operating-system reserve, memory used by HANA systems, allocated but unused memory, capacity set aside for replicas from other sites, and remaining free memory. By default, the reserve is 10% of the first 64 GiB and 3% of the remainder, unless a host has a different reserve configured. System usage is based on its 30-day peak. If allocations exceed physical memory, the software reports overbooking rather than displaying a negative free-capacity figure.
For SAP HANA system replication, the software checks whether the secondary host could accommodate the primary system’s allocation after a takeover. It reports whether the system fits, fits after named test or development systems are stopped, falls short by a stated number of GiB, or has an unknown status. Production systems belonging to other customers are not treated as stoppable. A replication status older than an hour or a memory reading older than 24 hours produces an unknown result, not a passing check. Scale-out deployments are evaluated as a whole, using the weakest host pair.
Version 0.23 also proposes a host and replication-site partner for a new HANA system and estimates memory runway by site and quarter, using planned go-lives weighted by probability. A new SAP Operations workspace displays free HANA memory, production systems without replication, takeovers that would fail, and hosts above 90% utilization. Rymvard says HANA instances are mirrored into its compute view so SAP memory can appear in customer showback and lifecycle planning.

Making HANA Failover Capacity Visible
The release addresses a specific planning problem for hosting providers: a data center may have capacity across its wider infrastructure while an individual HANA host or replication partner lacks enough memory for an allocation or takeover. Tracking those constraints separately can give operations teams a clearer view before placing a system or relying on a failover plan.
The age thresholds also affect how teams should read the results. Rymvard’s rule that stale readings return an unknown status avoids presenting old information as proof that capacity is available. At the same time, the practical value of the ledger depends on the accuracy and freshness of its inputs, as well as how well its rules represent each provider’s SAP environment.
The placement and quarterly runway views could help teams compare planned deployments with capacity at different sites. However, the release information does not establish that the product has reduced costs, improved reliability or produced customer outcomes. Its simulated tests describe reported behavior under one scenario, not demonstrated performance across live estates.

Read-Only SAP Data Connections
Rymvard says its collector connects to the SAP Host Agent over HTTPS and is limited to four read operations: ListInstances, ListDatabases, GetDatabaseStatus and GetComputerSystem. A separate monitoring connection uses TLS and a fixed set of six SELECT queries, with a 60-second limit per system and no more than eight systems queried at once. The company says the software does not write to SAP.
The product can also read system, customer and environment information through read-only interfaces in SAP Focused Run, ServiceNow, SAP Solution Manager via its System Landscape Directory, and SAP LaMa. Rymvard lists these as supported sources; the release material does not say that customers must connect all of them.
For its reported test, Rymvard used a simulated landscape with 200 HANA hosts, 161 systems and 39 replicated pairs. The company says the scenario identified one production system without replication, one takeover short by 512 GiB, one host overbooked by 128 GiB, and one replication in an error state. It describes the screens as illustrative and says they do not represent a real customer, site or outcome.
“Nothing is ever written to SAP.”

Customer Performance Remains Unreported
Rymvard describes version 0.23 as early-access software and has not identified a customer deployment or supplied customer results. The reported test findings come from a simulated landscape, so they do not establish how the checks perform in live customer environments, unusual SAP configurations or changing workloads.
The release describes its memory rules, query limits and freshness thresholds, but does not provide independent evaluations or further detail about validation in individual environments. It also does not state how often capacity readings update beyond the age limits that trigger an unknown result. Rymvard has not published pricing, a general-availability date or a named customer for the release.

Early-Access Evaluations Ahead
The next step is evaluation by early-access partners, with commercial terms arranged directly with Rymvard. The company has not announced when the software may become generally available or whether it will publish standard pricing. Further evidence from live deployments would be needed to show how the ledger performs across customer landscapes and whether its planning views lead to measurable operational outcomes.

Key Questions
What did Rymvard add in version 0.23?
The release adds SAP HANA memory accounting, placement proposals, replication takeover checks, and a workspace showing selected capacity and risk indicators.
Has Rymvard tested the software with customers?
The reported test used a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs. Rymvard has not identified a customer deployment or reported customer outcomes for this release.
How does the ledger handle old capacity data?
It reports an unknown status if replication information is more than an hour old or a memory figure is more than 24 hours old, rather than treating stale data as a passing result.
Does Rymvard say its software changes SAP systems?
No. Rymvard says its SAP connections are read-only and states, “Nothing is ever written to SAP.”
When will the product be generally available, and what will it cost?
The company has not announced a general-availability date or public price list. It says terms are arranged directly with early-access partners.
