Rymvard released 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 says the early-access software uses read-only SAP connections; its published test scenario was simulated, and no customer deployment or outcomes were supplied.
Rymvard released version 0.23 on October 4, adding SAP HANA memory accounting, placement planning and replication takeover checks to its data center capacity ledger, as described in the original analysis. The early-access release targets SAP hosting providers and operations teams, but the test results the company reported came from a simulated landscape, not a customer deployment.
The software breaks down each HANA host’s physical memory into an operating-system reserve, memory used by HANA systems, allocated but unused memory, capacity reserved for replicas from other sites, and remaining free memory, a key consideration in planning HANA capacity. Unless a host specifies another setting, the reserve is calculated as 10% of the first 64 GiB and 3% of the rest. System usage is based on its 30-day peak. If allocations exceed physical memory, the ledger shows overbooking instead of concealing it as negative free capacity.
For systems using SAP HANA system replication, Rymvard checks whether a secondary host could take on the primary system’s allocation, a capability relevant to the HANA memory hosting challenge. It reports whether the allocation fits, fits after named systems are stopped, falls short by a stated number of GiB, or cannot be assessed. The rules do not treat production systems belonging to other customers as stoppable. If replication status is more than an hour old, or a memory reading more than 24 hours old, the result is marked unknown rather than passed. Scale-out systems are assessed 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
For a hosting provider, general data center headroom does not necessarily mean a HANA workload can be placed or recovered safely. Memory can be the binding constraint: a site may have room in its wider infrastructure while a particular HANA host, or its replication partner, lacks enough memory for an allocation. Separating overbooking from takeover shortfalls gives operations teams a way to identify those conditions in the capacity ledger.
The age limits also affect how teams should read the results. By returning unknown for stale inputs, the software avoids treating old monitoring data as evidence that a takeover will fit. That approach may help surface gaps in operational information, but it also means the usefulness of the view depends on accurate, current measurements. Rymvard’s placement suggestions and quarterly runway estimates could support capacity discussions; the release material does not establish cost savings, improved reliability, or customer outcomes.
The distinction between a described capability and demonstrated performance matters for providers evaluating the product. The release outlines rules for placement and failover checks, but the company’s reported test does not show how the software performs in live customer estates, with unusual configurations or workloads that change over time.

Read-Only SAP Connections and Testing
Rymvard says its collector connects to the SAP Host Agent over HTTPS and uses 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 release also lists read-only sources for system, customer and environment information: SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa. Rymvard presents these as supported sources, not as a requirement to connect every system. The release description does not provide environment-by-environment validation results for these integrations.
Rymvard says it tested version 0.23 against a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs. In that scenario, the software 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. The company says the screens use an illustrative estate, not a customer environment; the results do not establish customer conditions or outcomes.
“Nothing is ever written to SAP.”

Customer Evidence Has Not Been Published
Rymvard describes version 0.23 as early access and has not identified a customer deployment or provided customer outcomes for the release. Its reported scenario is simulated, and the company says the displayed screens use an illustrative estate. The results therefore show what it says the software identified in that test, not how it performs in a live operation.
Other details also remain open. Rymvard has not published a public price list, saying pricing terms are arranged with early-access partners, and it has not announced a broader availability date. The release describes specific data-freshness thresholds and query limits, but does not provide independent evaluation results or detailed evidence covering every SAP configuration and changing workload. How integrations are validated in individual customer environments is also not specified.

Early-Access Partner Evaluations
The next step is evaluation by early-access partners, with commercial terms agreed directly with Rymvard. The company has not announced named customers, a general release date or public pricing. Evidence from live deployments, if made available later, would help show how the capacity ledger and takeover checks work across customer landscapes beyond the simulated test scenario.
Until then, providers considering the release can compare its documented inputs, reserve rules, freshness thresholds and read-only connections with their own SAP operations. The announcement does not say when Rymvard will publish further test results or a wider availability timetable.

Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA host-memory accounting, proposed placement of new systems, replication takeover checks, memory runway estimates and an SAP Operations workspace.
Has Rymvard reported a customer deployment?
No customer deployment or customer outcomes were supplied in the release material. Rymvard’s reported results came from a simulated landscape.
Does the software write to SAP?
Rymvard says its SAP connections are read-only and states, “Nothing is ever written to SAP.” The release describes specific read operations and monitoring queries.
When does the software mark a takeover result unknown?
Rymvard says a replication status more than one hour old, or a memory reading more than 24 hours old, produces an unknown result rather than a pass.
When will version 0.23 become generally available?
The company has not announced a broader availability date. It says the software is in early access, with terms arranged directly with partners.
