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 tested the early-access software on a simulated landscape, and has not identified a customer deployment or reported customer outcomes.
Rymvard released version 0.23 of its data center capacity ledger on October 4, adding tools to track SAP HANA memory, propose system placements and check whether replication partners could take over workloads. The original analysis describes the release. The early-access release is aimed at SAP hosting providers and operations teams, but the company’s reported test results are from a simulated landscape, not a customer deployment.
The software breaks down memory on each HANA host into the operating-system reserve, memory used by HANA systems, allocated but unused memory, capacity reserved for replicas from other sites and remaining free capacity. Its 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. Memory allocations that exceed physical capacity are shown as overbooking rather than being represented as negative free memory.
For systems using HANA system replication, Rymvard checks whether the secondary host could accommodate the primary system’s allocation after a takeover. It reports whether the workload fits, fits only 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 assumed to be stoppable. A replication status older than one hour or a memory reading older than 24 hours produces an unknown result. Scale-out systems are assessed as a whole, using 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 using planned go-lives weighted by their probability. A new SAP Operations workspace highlights free HANA memory, production systems without replication, takeovers that would fail and hosts above 90% utilization. Rymvard says HANA instances are mirrored into its compute view so their memory can appear in customer showback and lifecycle planning.

Making HANA Failover Capacity Visible
The release focuses on a constraint that can be hidden by broader data center capacity figures: a site may have room in its power or facility plans while a particular HANA host, or its replication partner, lacks enough memory for a workload. Separating overbooking from available capacity, and showing potential takeover shortfalls, could help operations teams identify those limits during placement planning rather than discovering them during a failover.
That usefulness depends on the quality and freshness of the source data. Rymvard’s choice to label stale readings as unknown avoids treating old information as proof that capacity is available. The placement proposals and runway estimates may help providers compare planned deployments across sites, but the release materials do not establish cost savings, improved reliability or other customer outcomes. The reported scenarios demonstrate the software’s described checks, not their performance in live operations.

Read-Only SAP Data Connections
Rymvard says its collector connects to SAP Host Agent over HTTPS and is limited to four read operations: ListInstances, ListDatabases, GetDatabaseStatus and GetComputerSystem. A separate monitoring connection uses TLS and six fixed 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 describes read-only access to system, customer and environment information through SAP Focused Run, ServiceNow, SAP Solution Manager via its System Landscape Directory, and SAP LaMa. These are listed as supported sources; the description does not say that customers must connect all of them. Rymvard reported testing version 0.23 with a simulated estate of 200 HANA hosts, 161 systems and 39 replicated pairs. In that scenario, the software flagged 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 said the displayed screens use an illustrative estate, not a customer environment.
“Nothing is ever written to SAP.”

Live Customer Results Not Yet Reported
Rymvard describes version 0.23 as early access and has not named a customer deployment or provided customer outcomes. The simulated test does not show how the product performs across live SAP landscapes, less common configurations or workloads that change over time. Independent evaluation results are also not included in the release information.
The company has not published prices, saying terms are arranged with early-access partners. The release describes supported connections and data-age thresholds, but does not provide details on validation in each customer environment or update speed beyond those thresholds. A broader availability date and the number or identity of early-access partners have not been announced.

Early-Access Partner Evaluations
The immediate next step is evaluation by early-access partners, with commercial terms arranged directly with Rymvard. The company has not announced a public price list, named a customer or set a date for broader availability. Evidence from partner deployments, if released, would help clarify how the memory ledger and takeover checks perform against real SAP environments and changing workloads.

Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA memory accounting, proposed host and replication-site placements, takeover-capacity checks and a workspace showing selected operational indicators.
Was the software tested in a customer data center?
Rymvard reported testing against a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs. The company said its displayed examples do not represent a customer environment.
How does the product treat outdated capacity data?
It returns an unknown takeover status if replication information is more than an hour old or a memory figure is more than 24 hours old, rather than treating the check as a pass.
Does Rymvard write data to SAP?
Rymvard says its SAP connections are read-only and states, “Nothing is ever written to SAP.” The release lists specific read operations and monitoring queries.
When will Rymvard 0.23 be generally available?
No broader availability date has been announced. The release is in early access, with terms arranged directly with partners.
