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 says the release uses read-only SAP connections; its published test results are from a simulated estate, not a customer deployment.

Rymvard released version 0.23 on October 4, 2026, adding SAP HANA memory accounting and replication takeover checks to its data center capacity ledger, as outlined in the original analysis. The early-access release is aimed at SAP hosting providers and operations teams that need to see whether hosts have enough memory for system placement or failover; the company’s reported test results come from a simulated estate, not a customer deployment.

The software breaks each HANA host’s physical memory into an operating-system reserve, HANA system usage, allocated but unused capacity, replica reservations and memory still free. The default reserve is 10 percent of the first 64 GiB and 3 percent of memory above that amount, unless a host has a different reserve configured. System usage is calculated from its 30-day peak. If allocations exceed physical memory, the ledger labels the host overbooked rather than presenting a negative free-memory figure.

For systems using HANA system replication, Rymvard checks whether the secondary host could accommodate the primary system’s allocation after a takeover. The result is reported as fits, fits after stopping named systems, does not fit with a shortfall in GiB, or unknown. The software may count specified test or development systems as stoppable, but does not treat other customers’ production systems that way. For scale-out systems, it assesses the system as a whole based on the weakest host pair.

Rymvard says results are marked unknown if replication status is more than one hour old or memory data is more than 24 hours old. 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 their probability. A new SAP Operations workspace displays free HANA memory, production systems without replication, failed takeover checks and hosts above 90 percent utilization.

Why HANA Failover Memory Matters

For a data center operator, total facility capacity does not necessarily mean a particular HANA host has enough memory for a new system or a replicated workload after a failure. Host-level accounting and takeover shortfalls can expose constraints that a wider view of data center capacity may not show. That can help teams identify placement or replication problems during planning, rather than relying on a broad estimate of available infrastructure.

The stale-data rules also affect how operators should read the results: an outdated measurement is not counted as evidence that a takeover will succeed. This cautious treatment may make gaps in monitoring visible, but the usefulness of the ledger still depends on the accuracy and freshness of its inputs. Rymvard’s placement proposals and quarterly runway estimates could help teams compare expected deployments across sites; the release material does not establish that they reduce costs, improve reliability or produce particular customer outcomes.

That distinction matters because the product is early access, and the reported checks do not establish how it performs across live customer environments, changing workloads or unusual SAP configurations. The release describes the functionality and the test scenario, not independent validation or customer results.

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 its software does not write to SAP.

The release also names 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 says HANA instances are mirrored into its compute view so SAP memory can appear in customer showback and lifecycle planning. The announcement lists these as supported sources; it does not say that every integration must be used together.

For its reported test, Rymvard used a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs. In that scenario, it says 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 displayed screens use an illustrative estate, not a customer environment, and do not represent a real customer, site or outcome.

“Nothing is ever written to SAP.”

Customer Testing Remains Unreported

Rymvard has not identified a customer deployment or supplied customer outcomes for version 0.23. The test figures are from a simulated landscape, so they do not show how the product performs in a live hosting environment. The company has also not published a public price list, saying terms are agreed with early-access partners.

The release describes its calculation rules and data-age thresholds, but leaves open how the software handles every SAP configuration and how integrations are validated in individual environments. It does not provide independent evaluations, live performance results or further details about update speed beyond the stated thresholds. Whether the proposed placement and runway views produce operational benefits remains unverified by the information provided.

Early-Access Partner Evaluations

The immediate next step is evaluation by early-access partners, with pricing arranged directly with Rymvard. The company has not announced a broader availability date, public pricing or a named customer deployment. Further evidence about performance in customer environments, integration behavior and operational outcomes would be needed to assess how the release works beyond its simulated test.

Key Questions

What did Rymvard add in version 0.23?

It added SAP HANA host memory accounting, system placement proposals and replication takeover checks to its data center capacity ledger. The release also includes site-level memory runway estimates and a new SAP Operations workspace.

Does Rymvard write data to SAP?

Rymvard says its SAP connections are read-only and that the software does not write to SAP. It describes specific read operations for the SAP Host Agent and a separate connection using a fixed set of SELECT queries.

What does a takeover result of “unknown” mean?

Rymvard says it returns unknown if replication status is more than one hour old or memory data is more than 24 hours old. The result does not count stale information as proof that a secondary host can accommodate a takeover.

Were the reported results measured at a customer data center?

No customer deployment was identified. Rymvard says its results came from a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs, and that its example screens show an illustrative estate.

When will Rymvard 0.23 be generally available?

The company has not announced a broader availability date. The release is described as early access, with evaluation by partners and pricing arranged directly with Rymvard.
