Rymvard released early-access version 0.23 on October 4, 2026, adding SAP HANA memory accounting, placement proposals and replication takeover checks to its data center capacity ledger. The company tested the software against a simulated estate and has not reported customer deployments or outcomes for this release.
As described in the original analysis, Rymvard released version 0.23 on October 4, adding SAP HANA memory accounting, placement proposals and replication takeover checks to its data center capacity ledger. The early-access update targets SAP hosting providers and operations teams, but Rymvard’s reported tests used a simulated landscape, not a customer deployment.
The software divides each HANA host’s physical memory among the operating system, HANA systems, allocated-but-unused capacity, memory reserved for replicas from other sites and free memory. Its default operating-system reserve is 10 percent of the first 64 GiB and 3 percent of the remaining memory, unless a host has a different reserve configured. System usage is calculated from its 30-day peak. If allocations exceed physical memory, the ledger marks the host as overbooked rather than showing negative free capacity.
For HANA system replication, version 0.23 checks whether a secondary host could take over the primary system’s allocation. It reports whether the allocation fits, fits after named test or development systems are stopped, falls short by a stated number of GiB, or cannot be assessed. Other customers’ production systems are not assumed to be stoppable. A replication status older than one hour or a memory reading older than 24 hours produces an unknown result, not a pass. Scale-out systems are assessed as a whole, using the weakest host pair.
The release 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, supporting data center capacity planning. A new SAP Operations workspace highlights free HANA memory, production systems without replication, takeovers that would fail and hosts above 90 percent utilization. Rymvard says HANA instances are mirrored into its compute view for customer showback and lifecycle planning.

Making HANA Failover Capacity Visible
The update addresses a specific planning problem for providers: a data center may have capacity across its wider infrastructure while an individual HANA host, or its replication partner, lacks the memory needed for a workload or takeover. By showing overbooking and takeover shortfalls separately, the ledger is intended to make those constraints visible before placement decisions or a failover.
The practical value depends on the accuracy and freshness of the data feeding the ledger. Rymvard’s rule that stale readings produce an unknown status avoids treating old information as evidence that capacity is available. Placement suggestions and quarterly runway estimates may help teams compare planned deployments across sites, but the release materials do not establish that the features improve reliability, reduce costs or produce other customer outcomes.

Read-Only SAP Data Sources
Rymvard says its collector connects to 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 product does not write to SAP.
The release also lists read-only sources for landscape information: SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa. These are described as supported sources; the release does not say that customers must connect all of them. Rymvard reports testing version 0.23 on a simulated estate of 200 HANA hosts, 161 systems and 39 replicated pairs. In that scenario, it flagged one production system without replication, a takeover short by 512 GiB, one host overbooked by 128 GiB and one replication in an error state.
“Nothing is ever written to SAP.”

Customer Results Are Not Yet Reported
Rymvard describes version 0.23 as early access and has not identified a customer deployment or supplied customer outcomes for this release. It says the displayed screens use an illustrative estate, and that the reported test results came from a simulated environment rather than a customer site. The results therefore do not establish performance across live landscapes, unusual configurations or changing workloads.
The release does not provide independent evaluations, a public price list or detailed validation results for individual integrations. Pricing is arranged with early-access partners. Rymvard also has not described how quickly readings update beyond the stated age thresholds or how the software handles every possible SAP configuration. These points remain open for prospective users evaluating the release.

Early-Access Evaluations Ahead
The next stated step is evaluation by early-access partners, with commercial terms agreed directly with Rymvard. The company has not announced a broader availability date, public pricing or a named customer deployment. Further evidence from live use would be needed to judge how the accounting and takeover checks perform in customer environments.

Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA memory accounting, system placement proposals, replication takeover checks and a workspace for tracking HANA capacity indicators.
Was version 0.23 tested at a customer site?
No customer deployment is identified in the release material. Rymvard reports testing against a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs.
How does the software treat stale capacity data?
It returns an unknown takeover status if replication data is more than one hour old or a memory figure is more than 24 hours old, rather than treating the result as a pass.
Does Rymvard write data to SAP?
Rymvard says its SAP connections are read-only and that the product does not write to SAP. The release describes specific read operations and monitoring queries.
When will the product be generally available?
Rymvard has not announced a broader availability date. The release says the immediate next step is evaluation by early-access partners.
