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 software connects to SAP through read-only interfaces; its reported results came from a simulated estate, and it has not identified a customer deployment.
Rymvard released version 0.23 on October 4, adding SAP HANA memory accounting, system placement proposals and replication takeover checks to its data center capacity ledger, as detailed in the original analysis. The early-access release targets SAP hosting providers and operations teams, but the company’s published test results are from a simulated estate, 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. Rymvard sets the default operating-system reserve at 10 percent of the first 64 GiB and 3 percent of memory above that, unless a host has a different reserve configured. System usage is based on its 30-day peak. If allocations exceed physical memory, the ledger shows overbooking rather than disguising it as negative free capacity.
For systems using SAP HANA system replication, the release checks whether the secondary host could take on the primary system’s allocation after a takeover. It returns one of four results: fits, fits after stopping named systems, does not fit with a shortfall in GiB, or unknown. Named test or development systems may be treated as stoppable, but production systems belonging to other customers are not. A replication status older than one hour or a memory reading older than 24 hours 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 memory runway by site and quarter, weighting planned go-lives by their probability. A new SAP Operations workspace shows four indicators: free HANA memory, production systems without replication, takeovers expected to 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 release addresses a specific planning problem: a data center can have capacity across its wider infrastructure while a particular HANA host or replication partner lacks the memory needed for a system allocation or takeover. Tracking free memory, overbooking and replica reservations separately could help providers identify those constraints before placing a system or responding to a failure.
That potential depends on the accuracy and freshness of the information feeding the ledger. Rymvard’s rule that stale readings produce an unknown result rather than a pass avoids treating outdated data as proof that a failover will work. The placement proposals and quarterly runway estimates may also help teams compare planned deployments against site capacity. However, the release materials do not establish savings, improved reliability or customer outcomes.
For operators assessing the product, the test scope matters. The release describes the checks and the company’s stated rules, but a simulated environment does not show how the ledger performs across live customer landscapes, unusual SAP configurations or workloads that change over time.

Read-Only SAP Data Connections
Rymvard says its collector communicates with 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 product does not write to SAP.
For landscape information, Rymvard also lists read-only connections to SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa. The release describes these as supported sources; it does not say that customers must connect all of them. Rymvard reports testing version 0.23 against a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs.
In that simulation, the company 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. Rymvard says the screens use an illustrative estate rather than a customer environment; the examples do not establish a real customer, site or operational outcome.

Customer Results Remain Unreported
Rymvard describes version 0.23 as early-access software and has not named a customer deployment or supplied customer outcome data for the release. Its reported findings come from a simulated landscape, and the company says the illustrative screens do not represent a real customer environment.
The release does not provide independent evaluations or performance data from live installations. It also leaves open how the software handles every SAP configuration, how integrations are validated in individual environments, and how quickly readings update beyond the stated age thresholds. Rymvard has not published a price list, saying early-access terms are arranged directly with partners.

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. Evidence from live deployments, if published, would help clarify how the memory accounting and takeover checks perform against actual operating data and configurations.
Until then, the confirmed development is the release of the described planning features and the company’s simulated test results. Whether the ledger changes capacity planning or failover outcomes in production remains to be demonstrated.

Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA host memory accounting, proposed placement for new systems, replication takeover checks and estimates of memory runway by site and quarter.
Has Rymvard reported a live customer deployment?
No customer deployment or customer outcome was identified in the release material. The company’s reported test results used a simulated estate.
How does the software handle old capacity data?
Rymvard says a replication status older than one hour or a memory reading older than 24 hours results in an unknown takeover status, rather than a passing result.
Does the software write to SAP systems?
Rymvard says it does not write to SAP. The release describes read-only SAP Host Agent operations and a separate connection using a fixed set of SELECT queries.
When will the product be generally available?
Rymvard has not announced a broader availability date. The immediate next step is evaluation by early-access partners.
