Rymvard released early-access version 0.23 on October 4, 2026, adding SAP HANA memory accounting, placement proposals and replication takeover checks to its capacity ledger. The company tested it against a simulated landscape of 200 hosts; it has not reported customer deployment results.
Rymvard released version 0.23 on October 4, adding SAP HANA memory accounting and failover-capacity checks to its data center capacity ledger. The early-access software is aimed at SAP hosting providers and operations teams, but the company’s published test results come from a simulated estate, not a customer deployment.
The release breaks down each HANA host’s physical memory into operating-system reserves, memory used by HANA systems, allocated but unused capacity, capacity reserved for replicas from other sites, and memory still free. The default reserve is 10% of the first 64 GiB and 3% of the remaining memory, unless a host has a different reserve configured. HANA system usage is calculated from its 30-day peak. When allocations exceed physical memory, the ledger shows overbooking rather than representing free memory as a negative value.
For SAP HANA system replication, the software checks whether a secondary host could accommodate the primary system’s allocation after a takeover. It reports whether the allocation fits, fits if named test or development systems are stopped, does not fit (with the shortfall in GiB), or cannot be assessed. Production systems belonging to other customers are not treated as stoppable. A replication status older than one hour or a memory figure older than 24 hours produces an unknown result, rather than a passing check. Scale-out systems are assessed as a whole, based on the weakest host pair.
Rymvard also says the release 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 probability. A new SAP Operations workspace displays four indicators: free HANA memory, production systems without replication, takeovers that would fail, and hosts above 90% utilization. The company says HANA instances are mirrored into its compute view so memory can be included in customer showback and lifecycle planning.

HANA Memory and Failover Capacity
The feature targets a specific capacity-planning problem: a data center can have room in its wider infrastructure while a HANA host or replication partner lacks enough memory for a system allocation. By distinguishing free memory, overbooking and takeover shortfalls, the ledger could help providers spot constraints before placing a system or relying on a secondary site during an outage.
That value depends on the accuracy and freshness of the data feeding the ledger. The rule that stale readings return an unknown status avoids treating old information as evidence that capacity is available. Placement proposals and quarterly runway estimates could help teams compare planned deployments with site capacity, but the release provides no evidence of cost savings, improved reliability or other customer outcomes. Those are potential uses, not demonstrated results.

Read-Only SAP Data and Test Scope
Rymvard says its collector connects to SAP Host Agent over HTTPS and permits 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. Rymvard says it does not write to SAP.
The company also lists read-only connections to SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa for system, customer and environment information. The release describes these as supported data sources; it does not say that customers must connect all of them.
Rymvard says it tested version 0.23 against a simulated landscape 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 displayed screens use an illustrative estate and do not represent a real customer, site or outcome.

Customer Results Remain Unreported
Rymvard describes version 0.23 as early access and has not named a customer deployment or provided customer outcomes for the release. The simulated test shows how the software behaved in one constructed landscape; it does not establish performance in live customer environments, unusual SAP configurations or workloads that change over time.
The release description also does not provide independent evaluations, pricing, or a broader availability date. Rymvard says early-access terms are agreed directly with partners. Further detail is not supplied on how integrations are validated in individual environments or how often readings update beyond the stated age thresholds. The reported checks and results should therefore be understood as company descriptions of the product, not independent confirmation of operational impact.

Early-Access Partner Evaluations
The next stated step is evaluation with early-access partners, with pricing arranged directly by Rymvard. The company has not announced a public price list, a general release date or a named customer. Further reporting on customer deployments, independent testing and how the checks perform against live HANA estates would help show whether the planning features deliver practical operational benefits.

Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA host-level memory accounting, system placement proposals, replication takeover-capacity checks and site-by-site memory runway estimates to its capacity ledger.
Has the software been tested at a customer site?
Rymvard reports testing against a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs. It has not reported a customer deployment or customer results for this release.
How does the takeover check handle stale information?
A replication status more than one hour old or a memory figure more than 24 hours old results in an unknown status, rather than a pass.
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?
The company has not announced a broader availability date. The release is described as early access, with partner terms arranged directly with Rymvard.
