Rymvard released 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 reports tests using a simulated estate, not a customer deployment, and says the software connects to SAP through read-only interfaces.
Rymvard released version 0.23 on October 4, adding SAP HANA memory accounting and replication-capacity checks to its data center ledger, as detailed in the original analysis. The early-access software is aimed at SAP hosting providers and operations teams planning system placement and failover capacity; the company’s reported test results came from a simulated estate, not a customer deployment.
For each HANA host, the ledger separates physical memory into an operating-system reserve, memory used by HANA systems, allocated but unused memory, capacity set aside for replicas from other sites, and 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. System usage is based on its 30-day peak. Allocations exceeding physical memory are shown as overbooking rather than being concealed as negative free capacity.
For HANA System Replication, Rymvard checks whether a secondary host could take over the primary system’s allocation. Results are reported as fits, fits after named systems stop, does not fit with a shortfall in GiB, or unknown. The tool may count named test or development systems as stoppable, but does not treat other customers’ production systems that way. A replication status older than an hour or a memory reading older than 24 hours results in an unknown status. Scale-out systems are evaluated as a whole, based on the weakest host pair.
The release also 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. For related infrastructure planning, see rack-level tracking for data center expansion. A new SAP Operations workspace displays free HANA memory, production systems without replication, takeovers expected to fail, and hosts above 90% utilization. Rymvard says HANA instances are mirrored into its compute view for customer showback and lifecycle planning.

Making HANA Failover Capacity Visible
HANA memory can constrain a hosting environment even when other data center resources appear available. A site may have room in its broader infrastructure while an individual host—or the secondary host expected to take over—lacks enough memory for a workload. By displaying overbooking and takeover shortfalls separately, Rymvard’s ledger is designed to help teams spot those constraints when considering placements or reviewing failover readiness.
The distinction between a passing check and an unknown result also matters operationally. Rymvard says it will not report a takeover as fitting when replication status or memory data has exceeded specified age limits. That approach makes data freshness visible, but the usefulness of the assessment still depends on the accuracy and timeliness of information from connected systems. The release describes planning functions; it does not establish that they have reduced costs, improved reliability, or produced customer outcomes.

Read-Only SAP Data Connections
Rymvard says its collector communicates with 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 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 details. These are described as supported sources, not as a set of tools that must all be installed together. Rymvard characterizes version 0.23 as early-access software; its announcement does not provide independent validation or live-customer performance evidence.
“Nothing is ever written to SAP.”

What the Simulated Test Shows
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, a takeover short by 512 GiB, a host overbooked by 128 GiB, and a replication in an error state. The company says the screens use an illustrative estate, not a customer environment, and the examples do not represent a real customer, site or outcome.
No customer deployment or customer outcomes were identified in the release material. It also does not provide independent evaluations, a public price list, or detailed evidence of behavior across varied customer configurations and changing workloads. Rymvard says early-access pricing is arranged with partners. The announcement gives the stated age thresholds for data, but does not explain how quickly readings refresh in every deployment or how all possible SAP configurations are handled.
Early-Access Partner Evaluations
The immediate next step is evaluation by early-access partners, with commercial terms agreed directly with Rymvard. The company has not announced a broader availability date, public pricing, or a named customer deployment. Further information from partner use could help establish how the capacity ledger performs with live landscapes and whether its placement and takeover assessments match operational conditions.
Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA host-memory accounting, system placement proposals, replication takeover checks and quarterly memory-runway estimates to its data center capacity ledger.
Has Rymvard reported a live customer test?
No customer deployment or customer outcome was identified in the release material. The reported results came from a simulated estate of 200 HANA hosts, 161 systems and 39 replicated pairs.
How does the software report takeover capacity?
It reports whether a takeover fits, fits after named systems stop, does not fit and by how many GiB, or is unknown. It returns unknown when replication status is more than an hour old or a memory figure is more than 24 hours old.
Does Rymvard write data to SAP?
Rymvard says its connections use read-only interfaces and states, “Nothing is ever written to SAP.” Its announcement lists specific SAP Host Agent operations and other supported read-only sources.
When will the product be generally available, and what will it cost?
The release does not give a broader availability date or public price list. Rymvard says early-access terms are arranged directly with partners.
