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 estate, not a customer deployment, and has not reported customer outcomes.
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 described in the original analysis. The early-access software is aimed at SAP hosting providers and operations teams, but the company’s reported tests used a simulated landscape rather than a customer deployment.
The release breaks down memory on each HANA host into the operating-system reserve, memory used by HANA systems, allocated but unused memory, capacity set aside for replicas from other sites, and unallocated memory. Unless a host has a different setting, the reserve is calculated as 10% of the first 64 GiB and 3% of remaining memory. System usage is based on its 30-day peak. Allocations that exceed physical memory are shown as overbooking rather than being hidden as negative free capacity.
For HANA System Replication, the software checks whether a secondary host could take over the primary system’s allocation. Rymvard reports one of four results: fits, fits after named systems are stopped, does not fit with a shortfall stated in GiB, or unknown. It may treat named test or development systems as stoppable, but does not treat other customers’ production systems that way. Scale-out systems are assessed together, using the weakest host pair.
Data age can prevent a pass: a replication status more than one hour old, or a memory reading more than 24 hours old, results in an unknown status. The release also proposes a host and replication-site partner for a new system and estimates memory runway by site and quarter, using planned go-lives weighted by their probability. Rymvard says HANA instances are mirrored into its compute view for customer showback and lifecycle planning.

Making HANA Failover Capacity Visible
HANA capacity planning can be constrained by memory at a particular host, even when the wider data center has room in areas such as power or floor capacity. By distinguishing free memory, overbooking and replica reservations, the ledger is designed to show where a planned system or a failover could run into a local shortage.
The takeover checks may give operations teams a way to identify a replication partner that cannot accept a primary system’s allocation before an outage or planned change. That value depends on the accuracy and freshness of the underlying information. Returning unknown for stale measurements avoids treating old data as evidence that capacity is available, but it does not establish that the data is complete or accurate in every installation.
Rymvard’s test examples illustrate the types of conditions the software is intended to flag, not demonstrated customer benefits. The company has not reported that the release reduced costs, prevented outages or improved reliability in a live environment. Readers evaluating the release should distinguish those intended uses from verified operational outcomes, which have not been provided.

Read-Only SAP Data Connections
Rymvard says its collector connects to the 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 up to eight systems queried at once. The company says the software does not write to SAP.
The release also lists read-only sources for landscape information: SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa. Rymvard presents these as supported sources; its description does not say that customers must connect all of them.
For version 0.23, Rymvard reports testing against a simulated estate of 200 HANA hosts, 161 systems and 39 replicated pairs. In that scenario, it identified a 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 displayed screens use an illustrative estate, not a customer environment, and do not represent a real customer, site or outcome.
“Nothing is ever written to SAP.”

Customer Evidence Has Not Been Published
Rymvard describes version 0.23 as early access and has not named a customer deployment or supplied customer results. The simulated test does not show performance across live customer landscapes, unusual SAP configurations or changing workloads. Independent evaluations are also not included in the release information.
The company has not published pricing, saying terms are arranged with early-access partners. Details are also limited on how integrations are validated in individual environments or how often measurements update beyond the stated age thresholds. It is not clear when wider availability will begin.
Early-Access Partner Evaluations
The next stated step is evaluation with early-access partners, with pricing arranged directly between Rymvard and those partners. The company has not announced a public price list, a named customer or a date for broader availability. Further information about deployments and results would be needed to judge how the planning checks perform with live SAP systems.
Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA host-memory accounting, system placement proposals, replication takeover checks and site-level memory runway estimates to its data center capacity ledger.
Was version 0.23 tested at a customer site?
Rymvard reports testing on a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs. It says the displayed examples are illustrative, not from a customer environment.
How does the software handle old capacity data?
It reports a takeover status as unknown if replication status is more than one hour old or a memory figure is more than 24 hours old.
Does Rymvard write data to SAP?
Rymvard says its SAP connections are read-only and that it does not write to SAP. Its description lists specific Host Agent operations and a separate monitoring connection.
When will the software be generally available?
No broader availability date has been announced. Rymvard says the immediate next step is evaluation by early-access partners.
