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 reports results from a simulated estate of 200 hosts, not a customer deployment, and says the product connects to SAP through read-only interfaces.
Rymvard released version 0.23 of its early-access data center capacity ledger on October 4, adding SAP HANA memory accounting, system placement proposals and checks of whether replication partners could take over workloads, as described in the original analysis. The update is aimed at SAP hosting providers and operations teams, but the test results disclosed by the company come from a simulated environment, not a customer deployment.
The software breaks down memory on each HANA host into the operating-system reserve, memory used by HANA systems, allocated but unused capacity, memory reserved for replicas from other sites and remaining free memory. Its default operating-system reserve is 10% of the first 64 GiB and 3% of memory beyond that, unless a host has a different reserve specified. System usage is calculated from its 30-day peak. Capacity allocated beyond physical memory is shown as overbooking rather than being concealed as negative free capacity.
For HANA system replication, Rymvard checks whether the secondary host could take the primary system’s allocation after a takeover. The software reports whether the allocation fits, fits if named systems are stopped, falls short by a stated number of GiB, or cannot be assessed. It may count specified test or development systems as stoppable, but does not treat other customers’ production systems that way. A replication status older than an hour or memory data older than 24 hours results in an unknown outcome rather than a passing check. 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 highlights 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 the memory information can be used in customer showback and lifecycle planning.

Making HANA Takeover Capacity Visible
The release addresses a planning problem for providers whose immediate constraint is memory capacity, not the overall capacity of a data center. A site may have room in its wider infrastructure while a particular HANA host, or the secondary host expected to handle a failover, lacks enough memory for the required allocation. Displaying overbooking and takeover shortfalls separately could help operations teams find those constraints before placing a system or relying on a replication plan.
The checks are only as useful as the underlying inventory and measurements. Rymvard’s choice to mark stale readings as unknown avoids presenting old information as proof that a takeover will fit, but also means teams may need to refresh data before relying on a result. The company describes planning functions and test scenarios; the supplied material does not establish that the release has improved reliability, reduced costs or produced other customer outcomes.

Read-Only SAP Data Connections
Rymvard says its collector connects to the SAP Host Agent over HTTPS and permits four read operations: ListInstances, ListDatabases, GetDatabaseStatus and GetComputerSystem. A separate TLS monitoring connection runs 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 software does not write to SAP.
For landscape information, the product can also read from SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa. Rymvard names these as supported sources; the release material does not say that customers must connect all of them. The company describes version 0.23 as early access, with terms arranged directly with partners rather than a published price list.
Rymvard says it tested the release against a simulated estate of 200 HANA hosts, 161 systems and 39 replicated pairs. In that scenario, it identified one production system without replication, a takeover short by 512 GiB, a host overbooked by 128 GiB and a replication in an error state. The company says the displayed screens use an illustrative estate and do not represent a customer, site or real-world outcome.

Customer Results Remain Unreported
Rymvard has not named a customer deployment or supplied customer outcome data for version 0.23. Its reported findings are from a simulated landscape, so they do not establish how the software performs across live SAP environments, unusual configurations or changing workloads. The company has not provided independent evaluation results in the supplied release information.
Further details are also unavailable on how integrations are validated in each customer’s environment or how often readings update apart from the stated age thresholds for unknown takeover results. Rymvard has not announced a broader availability date or public pricing. Early-access terms are arranged directly with participating partners.

Early-Access Partner Evaluations
The next stated step is evaluation by early-access partners, with pricing agreed directly with Rymvard. The company has not identified participating customers or set out a wider release timetable. Evidence from live deployments, if made available, would help show whether the ledger’s memory accounting and takeover checks work as intended across customer landscapes.
For now, the confirmed release describes the product’s rules, supported data sources and simulated test results. Prospective users will need to assess the integrations and data quality in their own environments; broader availability, customer outcomes and independent performance findings remain unannounced.

Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA host-memory accounting, placement proposals and checks of whether replication partners have enough memory to take over a system.
Were the reported results from a customer installation?
No. Rymvard says version 0.23 was tested against a simulated estate of 200 HANA hosts, 161 systems and 39 replicated pairs. It says the displayed examples do not represent a customer environment.
Does Rymvard write data to SAP?
Rymvard says its SAP connections are read-only and states, “Nothing is ever written to SAP.”
When does the software mark a takeover check as unknown?
According to Rymvard, a replication status older than one hour or a memory figure older than 24 hours produces an unknown result rather than a passing one.
When will the product be broadly available?
Rymvard has not announced a broader availability date or public price list. The current release is early access, with terms arranged directly with partners.
