Rymvard released version 0.23 on October 4, 2026, adding SAP HANA memory accounting, placement planning and replication takeover checks to its data center capacity ledger. The company says the software uses read-only SAP connections, but its reported tests used a simulated estate rather than 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. The early-access release is aimed at SAP hosting providers and operations teams that need to see whether individual hosts and replication partners can support planned or transferred HANA workloads, as described in the original analysis. Rymvard’s reported tests used a simulated environment, not a customer deployment.
The software breaks each HANA host’s physical memory into several categories: an operating-system reserve, memory used by HANA systems, allocated but unused memory, capacity held for replicas from other sites, and unallocated free memory. The default operating-system reserve is 10 percent of the first 64 GiB and 3 percent of the remaining memory, unless a host has a different reserve configured. System usage is calculated from its 30-day peak. If allocations exceed physical memory, the ledger reports overbooking instead of presenting the shortfall as negative free capacity.
For systems using HANA system replication, Rymvard checks whether a secondary host could accommodate the primary system’s allocation after a takeover. It can count named test or development systems as stoppable, but does not treat other customers’ production systems as available to stop. Results are reported as fits, fits after stopping named systems, does not fit with a shortfall in GiB, or unknown. A replication status older than an hour or memory data older than 24 hours leads to an unknown result rather than a pass. Scale-out deployments 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. Rymvard says the estimates weight planned go-lives by their probability. Its new SAP Operations workspace displays free HANA memory, production systems without replication, takeovers that would fail and hosts above 90 percent utilization. The company says HANA instances are mirrored into its compute view for customer showback and lifecycle planning.

HANA Capacity Beyond the Data Center
The release addresses a planning issue for providers whose immediate constraint is memory at a particular HANA host or replication site, rather than space or capacity elsewhere in a data center. A facility may have broad infrastructure headroom while a specific host cannot fit an allocation, or a secondary system may lack the memory needed during a failover. Separating overbooking from free capacity and showing takeover shortfalls could help operations teams identify those limits before placing a system or relying on a replica.
The value of those checks depends on the accuracy and freshness of the data. Rymvard’s policy of returning an unknown result when readings are stale avoids treating old information as evidence that capacity is available. The placement proposals and quarterly runway estimates may help teams compare planned deployments across sites, but the release materials do not establish cost savings, reliability gains or customer outcomes. The distinction between a product feature and demonstrated operational benefit remains material while the software is in early access.

Read-Only SAP Data Sources
Rymvard says its collector connects to the SAP Host Agent over HTTPS and is limited to 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. These are listed as supported sources, not as tools that must all be used together. Rymvard reports testing version 0.23 against a simulated landscape 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 one replication in an error state. The company says the displayed screens use an illustrative estate rather than a customer environment.
“Nothing is ever written to SAP.”

Customer Performance Still Unreported
Rymvard has not identified a customer deployment or provided customer results for version 0.23. Its stated test figures come from a simulated landscape, and the company says examples do not represent a real customer, site or outcome. The release describes the intended rules and data limits, but does not include independent evaluations or evidence of performance across live customer environments, unusual SAP configurations or changing workloads.
Other details are also not public, including how integrations are validated in each environment and the full range of configurations supported. Rymvard has not published prices; it says terms are arranged with early-access partners. The company has not announced a general availability date or named a customer.

Early-Access Partner Evaluations
The next step is evaluation by Rymvard’s early-access partners, with commercial terms negotiated directly. Those evaluations may provide evidence about how the accounting and takeover checks perform against real landscapes, but the company has not announced when results might be shared. A broader release date and public pricing remain unannounced.

Does Rymvard write data to SAP?
The company says its SAP connections are read-only and states, “Nothing is ever written to SAP.”
How does the software handle old capacity data?
Rymvard says a replication status more than an hour old or a memory figure more than 24 hours old produces an unknown result, rather than a passing capacity check.
