Rymvard released 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 early-access software on a simulated landscape, not a customer deployment, and has not published customer outcomes or a broader availability date.
As described in the original analysis, Rymvard released version 0.23 on October 4, adding SAP HANA memory accounting, host 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 test results came from a simulated landscape rather than a customer deployment.
The release divides memory on each HANA host 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. Unless a host has a different reserve configured, Rymvard sets aside 10% of the first 64 GiB and 3% of memory above that. System usage is calculated from its 30-day peak. If allocations exceed a host’s physical memory, the software flags overbooking rather than showing an artificially negative free-memory figure.
For systems using SAP HANA system replication, the ledger checks whether a secondary host has enough capacity to take over the primary system’s allocation. Rymvard says the check can count specified test or development systems as stoppable, but does not assume production systems belonging to other customers can be stopped. The result is reported as a fit, a fit after stopping named systems, a shortfall stated in GiB, or unknown.
The release also proposes a host and replication-site partner for a new HANA system and estimates memory runway by site and quarter, weighting planned go-lives by their 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, alongside considerations such as data center capacity constraints.

Making HANA Failover Capacity Visible
For providers running memory-intensive HANA workloads, a data center may have room in its wider infrastructure while an individual host or replication partner lacks enough memory for a system allocation. By separating host overbooking from free capacity and estimating whether replicas can be accommodated after a takeover, Rymvard’s ledger is designed to make those constraints visible during placement and operational planning.
The distinction matters before a deployment as well as during a failure: a proposed placement can be checked against the receiving host and replication site, while planned go-lives can be compared with forecast capacity. That may help teams spot a mismatch earlier, but the release does not establish cost savings, improved reliability or customer outcomes. Those remain potential uses rather than demonstrated results.
The software also treats stale data conservatively. Rymvard says a replication status older than one hour or a memory reading older than 24 hours returns “unknown” rather than a passing result. This avoids treating outdated information as evidence that takeover capacity is available, while making data freshness a practical factor for operators evaluating the checks.

Read-Only SAP Data Connections
Rymvard says its SAP Host Agent collector connects over HTTPS and is limited to four read operations: ListInstances, ListDatabases, GetDatabaseStatus and GetComputerSystem. A separate monitoring connection uses TLS, a fixed set of six SELECT queries, a 60-second limit per system and a maximum of eight systems queried at once. The company states that the product does not write to SAP.
For landscape information, Rymvard lists read-only connections to SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa. The release names these as supported sources; it does not say that customers must use all of them together. Scale-out systems are evaluated as a whole, with the weakest host pair determining the assessment.
Rymvard reports testing version 0.23 against a simulated estate 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 environment, not a customer estate.
“Nothing is ever written to SAP.”

Customer Results Remain Unreported
Rymvard describes version 0.23 as early-access software and has not identified a customer deployment or provided customer outcomes for the release. Its test figures come from a simulated landscape, so they do not show how the checks perform across live customer environments, unusual configurations or changing workloads.
The release also does not provide independent evaluations, pricing, a public availability schedule or detailed validation results for each supported integration. Rymvard says early-access terms are arranged directly with partners. Although it specifies when stale replication and memory data trigger an unknown result, the material does not detail update speeds beyond those thresholds or how every possible SAP configuration is handled.

Early-Access Partner Evaluations
The next step is evaluation by early-access partners, with commercial terms arranged directly with Rymvard. The company has not announced a named customer, a public price list or a date for broader availability. Any assessment of the product’s performance in live operations will depend on evidence from those evaluations, which has not yet been reported.

Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA memory accounting, proposed host and replication-site placement, takeover-capacity checks, quarterly memory-runway estimates and an SAP Operations workspace.
Was version 0.23 tested at a customer site?
No customer deployment was reported. Rymvard says its results came from a simulated estate of 200 HANA hosts, 161 systems and 39 replicated pairs.
How does the software report replication takeover capacity?
It reports whether a secondary can accommodate the primary system, whether it can do so after stopping named systems, a memory shortfall in GiB, or an unknown result. Stale replication or memory data can trigger the unknown status.
Does Rymvard write data to SAP?
Rymvard says its SAP connections are read-only and states, “Nothing is ever written to SAP.”
When will the software be generally available?
Rymvard has not announced a broader availability date. The immediate next step is evaluation with early-access partners.
