Rymvard released version 0.23 on October 4, 2026, adding SAP HANA host-memory accounting, placement proposals and replication takeover checks to its capacity ledger. The software is early access, and the company’s reported test results came from 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, as detailed in the original analysis. The early-access update is aimed at SAP hosting providers and operations teams, but Rymvard’s reported tests used a simulated landscape, not a customer deployment.
The ledger breaks each HANA host’s 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 remaining free memory. Unless a host has a different reserve configured, the default reserves 10 percent of the first 64 GiB and 3 percent of the remainder. System usage is based on its 30-day peak. If allocations exceed physical memory, the ledger reports overbooking rather than disguising it as negative free capacity.
For systems using HANA system replication, the software checks whether a secondary host could accommodate the primary system’s allocation after takeover. It reports whether the workload fits, fits after named test or development systems are stopped, falls short by a stated number of GiB, or cannot be assessed. Production systems belonging to other customers are not treated as stoppable. A replication status older than an hour or a memory reading older than 24 hours produces an unknown result rather than a pass. Scale-out systems are assessed as a whole using their 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. Rymvard says HANA instances are mirrored into its compute view, where they can appear in customer showback and lifecycle planning. Its new SAP Operations workspace displays indicators for free HANA memory, production systems without replication, takeovers that would fail and hosts above 90 percent utilization.

Making HANA Failover Capacity Visible
The release addresses a planning problem for providers whose limiting resource is memory rather than power. A facility can have capacity in its wider infrastructure while a specific HANA host—or the partner expected to take over during an outage—does not have enough memory for the workload. Separating overbooking from free capacity, and showing takeover shortfalls, could help operations teams identify those constraints before placing a system or needing to fail over.
The safeguards around old data matter because a stale reading cannot reliably prove that a host has room. By returning an unknown status when measurements pass the stated age limits, the software avoids presenting outdated capacity information as a successful takeover check. The placement and runway views may help teams compare planned deployments with site capacity, but the release provides no evidence of savings, improved reliability or other customer outcomes.
For prospective users, the distinction between a product feature and a demonstrated result is material. The release describes intended checks, but the supplied test scenario does not establish performance across live SAP environments, unusual configurations or changing workloads.

Read-Only SAP Connections and Test Scope
Rymvard says its collector communicates with 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.
For landscape details, Rymvard lists read-only connections to SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa. The release names these as supported information sources; it does not say customers must connect all of them.
Rymvard says it tested version 0.23 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, one takeover short by 512 GiB, one host overbooked by 128 GiB and one replication in an error state. The company says the screens use an illustrative estate and do not represent a customer, site or actual outcome.
“Nothing is ever written to SAP.”

Customer Evidence Is Still Pending
Rymvard describes version 0.23 as early-access software and has not identified a customer deployment or provided customer outcomes for the release. Its reported test results are from a simulation, so they do not show how the checks perform across real customer landscapes or less common SAP configurations. No independent evaluation is included in the supplied release information.
The company has not published pricing, saying terms are arranged with early-access partners. The release describes its data-age thresholds and query limits, but does not provide further detail on how integrations are validated in individual environments or how quickly readings update under normal operating conditions. It also does not establish whether the proposed views lead to measurable operational or financial benefits.

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 or public price list, and no named customer is included in the release information. Further evidence about live deployments, integration behavior and performance under changing workloads would help buyers judge how the simulated results translate to operational use.
Until such details are available, version 0.23’s stated capabilities can be assessed from its documented accounting rules, read-only connections and freshness thresholds, but its effectiveness in customer environments remains unverified.
