Rymvard released early-access version 0.23 on October 4, 2026, adding SAP HANA host memory accounting, placement proposals and replication takeover checks to its data center capacity ledger. The company tested the release on a simulated landscape, not a customer deployment; real-world outcomes and broader availability remain unreported.
Rymvard released version 0.23 on October 4, adding SAP HANA memory accounting and replication takeover checks to its data center capacity ledger, as described in the original analysis. The early-access software is aimed at SAP hosting providers and operations teams; the company’s published test results come from a simulated estate, not a customer deployment.
The release breaks 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’s default reserve is 10% of the first 64 GiB and 3% of memory above that, unless a host has a different reserve configured. System usage is calculated from its 30-day peak. If allocations exceed physical memory, the ledger displays overbooking rather than hiding it as negative free capacity.
For HANA system replication, the software checks whether a secondary host could take on the primary system’s allocation after a takeover. It can count specifically named test or development systems as stoppable, but does not assume that other customers’ production systems can be stopped. Results are reported as fits, fits after stopping named systems, a shortfall stated in GiB, or unknown. A replication status older than an hour or memory data older than 24 hours triggers an unknown result, not a passing check. Scale-out systems are evaluated as a whole using the weakest host pair.
Rymvard also says the release proposes a host and replication-site partner for a new system and estimates quarterly, site-level memory runway using planned go-lives weighted by probability. A new SAP Operations workspace displays 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 information can be used in customer showback and lifecycle planning.

Finding HANA Memory Before Failover
The release addresses a specific planning problem: a data center may have room in its broader infrastructure while a HANA host or replication partner lacks memory for a workload or takeover. Tracking overbooking and takeover shortfalls separately could help operations teams identify those constraints before placing a system or relying on a failover plan.
That value depends on the quality and freshness of the data feeding the ledger. Marking stale measurements as unknown rather than available avoids treating old information as evidence that capacity exists. Placement proposals and runway estimates may help teams compare planned deployments with site capacity, but the release material does not establish cost savings, improved reliability, or other customer outcomes.
The distinction between feature descriptions and demonstrated results matters for providers considering the software. Rymvard has described its checks and supplied a simulated test scenario, but has not reported performance in a live customer environment. The announced capabilities are not evidence that every configuration or changing workload will be represented accurately.

Read-Only SAP Data Connections
Rymvard says its collector connects to 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.
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. The announcement does not say that customers must connect all of these tools. They are presented as supported sources to add landscape information to the HANA memory view.
For version 0.23, Rymvard reports tests against a simulated estate of 200 HANA hosts, 161 systems and 39 replicated pairs. In that scenario, the software identified one production system without replication, a takeover short by 512 GiB, a 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 customer, site, or real outcome.
“Nothing is ever written to SAP.”

Live Customer Results Remain Unreported
Rymvard describes version 0.23 as early access and has not named a customer deployment or provided customer outcomes. Its published test figures are from a simulation, so they do not show how the software performs across live SAP landscapes, unusual configurations, or workloads that change over time.
The release describes data-age thresholds and query limits, but does not provide independent validation or detail on how integrations are checked in each customer environment. Rymvard has not announced a public price list; it says terms are arranged with early-access partners. A broader availability date also remains unannounced.

Early-Access Evaluations Ahead
The next stated step is evaluation by early-access partners, with commercial terms agreed directly with Rymvard. Those evaluations could provide evidence about how the memory ledger and takeover checks work in operating environments, but the company has not announced a schedule for publishing results.
Rymvard has not set a date for general availability, named a customer, or published pricing. Until it provides those details or reports live deployments, the release’s test results should be understood as simulated performance, not proof of customer outcomes.

Key Questions
What did Rymvard add in version 0.23?
Version 0.23 adds SAP HANA host memory accounting, system placement proposals, and checks of whether replication partners have enough memory for a takeover. It also adds an SAP Operations workspace with capacity and replication indicators.
Was the software tested at a customer site?
No customer deployment is identified in the release material. Rymvard reports testing against a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs.
Does Rymvard write data to SAP?
Rymvard says its SAP connections are read-only and that the product does not write to SAP. Its description lists Host Agent read operations and separate monitoring queries.
When does the software report an unknown takeover result?
According to Rymvard, a replication status older than one hour or memory data older than 24 hours produces an unknown result rather than a passing assessment.
When will Rymvard be generally available, and what will it cost?
The company has not announced a broader availability date or public price list. It says early-access terms are arranged directly with partners.
