Rymvard released early-access version 0.23 on October 4, 2026, adding SAP HANA memory accounting, placement proposals and replication takeover checks to its data center capacity ledger. The company tested the release against a simulated landscape; it has not reported customer deployment results.
Rymvard released version 0.23 of its data center capacity ledger on October 4, adding tools to track SAP HANA memory, propose system placement and check whether replication partners could take over workloads, as detailed in the original analysis. The early-access software is aimed at SAP hosting providers and operations teams, but the company’s reported test results are from a simulated estate, not a customer deployment.
The software breaks down each HANA host’s physical memory into the operating-system reserve, memory used by HANA systems, allocated but unused capacity, memory reserved for replication partners and remaining free memory. Unless a host has a different setting, the operating-system reserve is calculated as 10% of the first 64 GiB and 3% of memory above that. System usage is based on its 30-day peak. If allocations exceed physical memory, the ledger displays overbooking rather than disguising it as negative free capacity.
For systems using HANA system replication, the software checks whether the 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 that way. Results are reported as fits, fits after named systems stop, does not fit with a shortfall in GiB, or unknown. Replication status older than one hour or memory data older than 24 hours produces an unknown result rather than a passing one. 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 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 SAP memory can appear in customer showback and lifecycle planning.

Making HANA Failover Capacity Visible
The release addresses a specific planning problem for providers: a data center can have capacity across its broader infrastructure while an individual HANA host, or a replication partner, lacks enough memory for a workload. Showing overbooking and takeover shortfalls separately could help operations teams identify those constraints before placing a system or relying on a failover plan.
The value of those checks depends on the accuracy and timeliness of the underlying information. Rymvard’s rule that stale measurements produce an unknown status avoids treating outdated data as evidence that capacity is available. Placement proposals and quarterly runway estimates may also help teams compare planned deployments with site capacity. However, the release’s test scenarios do not establish cost savings, improved reliability or customer outcomes.
For providers considering the software, the distinction between a simulated test and a live installation matters. The announced rules describe how the product is intended to work, but do not show how it performs across real customer environments, unusual configurations or changing workloads.

Read-Only SAP Data Connections
Rymvard says its collector connects to SAP through read-only interfaces. Its SAP Host Agent connection uses HTTPS and permits four 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 a maximum of eight systems queried at once. The company says the software does not write to SAP.
The release also lists read-only information sources for system, customer and environment details: SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa. Rymvard describes these as supported sources; it does not say that customers must use them all together.
For its reported test, Rymvard used 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 shortfall of 512 GiB, an overbooked host by 128 GiB, and one replication in an error state. The company says the displayed screens use an illustrative estate and do not represent a real customer, site or outcome.
“Nothing is ever written to SAP.”

Customer Evidence Is Still Pending
Rymvard describes version 0.23 as early access and has not identified a customer deployment or supplied customer outcomes for the release. The test results are from a simulation, so they do not establish performance across live SAP landscapes or show whether the checks change operational outcomes.
The release also does not detail how the software handles every possible SAP configuration, how integrations are validated in individual environments, or how quickly readings update beyond the stated age thresholds. Rymvard has not published pricing, saying terms are arranged with early-access partners. Independent evaluations are not included in the supplied material.

Early-Access Evaluations Ahead
The next step is evaluation by early-access partners, with pricing arranged directly with Rymvard. The company has not announced a broader availability date, public price list or named customer. Evidence from partner deployments, including how the ledger performs with live workloads and changing capacity data, would help clarify the software’s practical value.

Key Questions
What did Rymvard add in version 0.23?
It added SAP HANA memory accounting, system placement proposals, replication takeover checks, and site-level memory runway estimates to its data center capacity ledger.
Has Rymvard reported results from a customer deployment?
No customer deployment or customer outcome is identified in the release material. The reported test used a simulated estate with 200 HANA hosts, 161 systems and 39 replicated pairs.
How does the software handle old capacity data?
It returns an unknown takeover result if replication status is more than one hour old or memory data is more than 24 hours old, rather than counting stale information as a passing check.
Does the software write to SAP?
Rymvard says its SAP connections are read-only and states: “Nothing is ever written to SAP.”
When will the product be generally available, and what will it cost?
The company has not announced a broader availability date or public pricing. It says early-access terms are agreed directly with partners.
