Rymvard released version 0.23 on October 4, 2026, adding SAP HANA memory accounting, system placement proposals and replication takeover checks to its data center capacity ledger. The early-access software uses read-only connections, and the company’s reported tests involved a simulated 200-host landscape rather than a customer deployment.
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, as described in the original analysis. The early-access release is aimed at SAP hosting providers and operations teams that need to track whether HANA hosts and failover partners have enough memory; Rymvard’s reported testing used a simulated estate, not a customer deployment.
The software divides each HANA host’s physical memory into an operating-system reserve, memory used by HANA systems, allocated but unused capacity, space reserved for replicas from other sites, and remaining free memory. The default operating-system reserve is 10% of the first 64 GiB and 3% of the remainder, unless a host has a different reserve configured. For system usage, Rymvard uses a system’s 30-day peak. Allocations that exceed physical memory are shown as overbooking rather than being concealed as negative free capacity.
For SAP HANA system replication, the ledger checks whether a secondary host could take over the primary system’s allocation. It may count named test or development systems as stoppable, but does not treat other customers’ production systems that way. The result is reported as “fits,” “fits after stopping named systems,” a shortfall in GiB, or “unknown.” A replication status more than one hour old, or a memory reading more than 24 hours old, produces an unknown result. Scale-out systems are assessed as a whole based on the weakest host pair.
Version 0.23 also proposes a host and replication-site partner for a new HANA system and estimates quarterly memory runway by site, weighting planned go-lives by their probability. Rymvard says HANA instances are mirrored into its compute view so memory can inform customer showback and lifecycle planning. A new SAP Operations workspace displays indicators for free HANA memory, production systems without replication, takeovers that would fail, and hosts above 90% utilization.

Spotting HANA Failover Gaps
For data center operators, usable capacity is not only a question of whether a facility has enough power or floor space. A particular HANA host, or the secondary host expected to take over during an outage, may lack enough memory even when the wider site appears to have room. By showing overbooking and takeover shortfalls separately, Rymvard’s ledger is designed to make those constraints visible during system placement and capacity planning.
The checks could help teams compare planned deployments with available memory across sites and identify replication arrangements that may need attention. But the release announcement does not establish that the software has reduced outages, improved reliability, saved money or produced other customer outcomes. Its practical value depends on accurate, current source data and how well the planning rules match each operator’s environment. Rymvard’s choice to return “unknown” for stale readings avoids treating outdated information as proof of available capacity, but also means operators must address data freshness before relying on a passing assessment.

How Rymvard Connects to SAP
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 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. Rymvard describes these as supported sources; the announcement does not say customers must connect all of them. The company tested version 0.23 against a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs. In that scenario, it reported 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 example screens use an illustrative estate, according to Rymvard.

Customer Evidence Is Still Pending
Rymvard describes version 0.23 as early-access software and has not identified a customer deployment or shared customer results for this release. The reported test is a simulated landscape, so it does not show performance across live customer systems, unusual SAP configurations or workloads that change over time. The company also has not published independent evaluations or real-world reliability data.
Further details are not provided on how integrations are validated in each customer environment or how readings update beyond the stated thresholds for stale memory and replication data. Rymvard has not disclosed public pricing; it says terms are arranged with early-access partners. The release describes intended functions and stated limits, but those claims have not been independently verified in the supplied material.

Early-Access Evaluations Ahead
The next step is evaluation by Rymvard’s early-access partners, with commercial terms agreed directly with the company. Those evaluations may clarify how the memory ledger and takeover checks behave in live SAP landscapes, including how teams handle data freshness and environment-specific configurations. Rymvard has not announced a broader availability date, public price list or named customer for version 0.23.

Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA memory accounting, proposed system placement, replication takeover checks and related capacity views to its data center ledger.
Has the software been tested in a customer data center?
Rymvard’s reported test used a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs. The company has not identified a customer deployment or supplied customer outcomes for this release.
How does it handle old memory or replication readings?
It reports the takeover result as unknown if replication status is more than one hour old or a memory figure is more than 24 hours old.
Does Rymvard write data to SAP?
Rymvard says its SAP connections are read-only and that it does not write to SAP. It lists specific Host Agent operations and other read-only interfaces used for landscape details.
When will version 0.23 be generally available?
No broader availability date has been announced. Rymvard says the software is in early access, with pricing terms arranged directly with participating partners.
