TL;DR
Rymvard released version 0.23 on Oct. 4, 2026, adding SAP and HANA hosting support to its data-center capacity ledger. The early-access software tracks HANA memory use and replication capacity, but its published test results come from a simulated estate, not a customer deployment.
Rymvard released version 0.23 on Oct. 4, 2026, adding SAP and HANA hosting support to its data-center capacity ledger. The early-access release is aimed at SAP hosting providers and operations teams, with tools to account for HANA memory, check whether replication partners can take over workloads, and plan capacity for upcoming systems.
The ledger breaks each HANA host’s physical memory into an operating-system reserve, memory used by HANA systems, allocated but unused memory, memory reserved for replicas at other sites, and free memory. By default, the reserve is 10% of the first 64 GiB and 3% of the remainder, unless a host specifies its own reserve. HANA system use is based on its 30-day peak. Allocations above physical capacity appear as overbooking rather than being concealed as negative free memory.
For each HANA system using system replication, Rymvard checks whether the secondary host can carry the primary system’s allocation after a takeover. The check can account for stopping test and development systems on the secondary, but it does not treat another customer’s production systems as stoppable. Results are reported as a fit, a fit after named systems are stopped, a failure with a shortfall in GiB, or unknown. If replication status is more than one hour old, or a memory reading is more than 24 hours old, the result is marked unknown. For scale-out systems, the overall assessment uses the weakest host pair.
The release also proposes a host and replication-site partner when placing a new HANA system, and converts planned go-lives, weighted by their probability, into a memory runway by site and quarter. HANA instances are mirrored into Rymvard’s compute view, allowing SAP memory to appear in customer showback and lifecycle planning. A new SAP Operations workspace highlights free HANA memory, production systems without replication, takeovers that would fail, and HANA hosts above 90% capacity.

Can Hosting Providers Track SAP HANA Memory In The Capacity Ledger?
Rymvard version 0.23 adds HANA memory accounting, replication takeover checks and capacity planning for SAP hosting teams. Published results come from a simulated estate, with customer performance still unreported.
See allocated capacity, replica reserves and takeover fit across sites.
Illustrative screens and simulated findings; no customer deployment results reported.
One host, five memory buckets
The ledger separates what is in use from what is committed, reserved for recovery or still available.
Illustrative host memory breakdown
Conceptual allocation view — not a reported customer host measurement.
10% of the first 64 GiB, then 3% of the remaining memory, unless the host defines its own reserve.
HANA system use is based on its 30-day peak to represent recent high-water demand.
Allocations above physical capacity are shown as overbooking instead of hidden as negative free memory.
Can the secondary carry the primary?
Each replication check compares the primary allocation with capacity at the secondary host after takeover.
The secondary has capacity to carry the primary system allocation.
A fit is possible after named test or development systems on the secondary are stopped.
The takeover does not fit; the result includes the capacity gap in GiB.
Evidence is stale, so the system cannot confirm a safe fit.
From live estate to planned runway
Version 0.23 connects current HANA capacity to placement proposals and probability-weighted demand.
Mirror HANA instances into the compute view for showback and lifecycle planning.
Assess host memory and whether replication partners can carry a takeover.
Propose a host and replication-site partner for a new HANA system.
Convert likely go-lives into a memory runway by site and quarter.
Free HANA memory
Unreplicated production and failing takeovers
Hosts above 90% capacity
Demand runway for upcoming systems
Plan demand across sites and quarters
Planned go-lives are weighted by probability and compared with available memory. The bars below are illustrative only.
Probability-weighted go-lives
Compare expected incoming memory demand with site capacity over time. Usefulness depends on complete, fresh ledger data and realistic probability estimates.
Simulated findings, not customer outcomes
Rymvard’s simulated landscape
The company says screens show a running product on an illustrative estate, not a customer environment. These results have not been independently validated in the release information.
“A replication status older than one hour or a memory figure older than 24 hours makes the result unknown — never fine.”Rymvard · Product description
“Nothing is ever written to SAP.”Rymvard · Read-only connection claim
Read-only access by design
Rymvard describes bounded reads from SAP and landscape tools. The approach does not by itself establish performance across customer environments.
A site-level collector communicates with SAP Host Agent over HTTPS. A separate connection reads HANA monitoring views using fixed queries, TLS and limits on query time and concurrency.
Four accepted reads: ListInstances, ListDatabases, GetDatabaseStatus and GetComputerSystem. Other operations are rejected.
Six fixed SELECT queries; 60-second limit per system and up to eight systems queried at once.
Read-only interfaces in SAP Focused Run, ServiceNow, SAP Solution Manager SLD and SAP LaMa.
Rymvard says its software does not write to SAP.
What providers should watch next
Version 0.23 is in early access. Pricing is agreed with early-access partners; no general-availability date or broader release schedule is stated.
Capabilities described
- HANA memory accounting and visible overbooking
- Replication takeover fit and stale-data status
- System placement proposals and quarterly runway planning
- SAP memory in customer showback and lifecycle planning
Evidence still open
- Customer deployment results and live-estate performance
- Number of early-access partners
- Independent validation of the simulated findings
- General-availability timing and published pricing
HANA Memory and Takeover Risk
For providers running SAP infrastructure, memory can become the binding capacity constraint before power does, according to Rymvard’s description of the product’s target use case. Tracking only current consumption may miss memory already allocated to systems, capacity reserved for replication, or the room needed to recover workloads after a site or host failure.
The release brings those factors into a shared capacity view. A takeover result marked unknown rather than safe when monitoring data is stale can help operators distinguish a verified fit from a lack of current evidence. Showing overbooking directly may also make it easier to spot commitments that exceed physical memory before adding more systems. These are product capabilities; Rymvard has not published evidence here of operational outcomes at a customer site.
Planning placements and probable go-lives against a quarterly memory runway could help hosting teams compare incoming demand with available capacity across sites. Its usefulness will depend on the freshness and completeness of the data connected to the ledger, as well as the accuracy of planned go-live probabilities.

Read-Only SAP Data Connections
Rymvard says the product connects to SAP in read-only mode. A site-level collector communicates with SAP Host Agent over HTTPS and accepts four read operations: ListInstances, ListDatabases, GetDatabaseStatus and GetComputerSystem. It rejects other operations. A separate connection queries HANA monitoring views using six fixed SELECT queries, with TLS, a 60-second limit per system and a maximum of eight systems queried at once.
Landscape information can also come from read-only interfaces in SAP Focused Run, ServiceNow, SAP Solution Manager through its System Landscape Directory, and SAP LaMa. Rymvard says the software does not write to SAP. The stated access limits and read-only design describe the product’s approach; they do not independently establish how it will perform across different customer environments.
Rymvard reports testing the release against a simulated landscape of 200 HANA hosts, 161 systems and 39 replicated pairs. In that simulation, it identified one production system without replication, one takeover that would not fit with a 512 GiB shortfall, one host overbooked by 128 GiB, and one replication in an error state. The company says the product is in early access and that displayed screens use an illustrative estate, not a customer environment.

Customer Performance Remains Unreported
Rymvard has not reported results from a customer deployment. Its published counts and detected capacity issues are from a simulated SAP landscape, and the company says the screens shown are based on an illustrative estate. It is not clear how the system performs across live customer environments, including estates with different configurations, data quality or monitoring practices.
The company has also not published pricing; it says terms are agreed with early-access partners. The release description does not specify how many partners are participating, when general availability might begin, or whether the simulation’s findings have been independently validated. Those points remain open.

Early-Access Rollout and Validation
Rymvard says version 0.23 is available in early access, with pricing handled through agreements with early-access partners. The next evidence to watch for is whether the company reports customer deployments, live-estate results or changes to the product’s SAP integrations and capacity checks. No general-availability date or broader release schedule has been announced in the information available.
Hosting providers considering the release would need to evaluate its connections and reporting against their own SAP landscapes, including the freshness of replication and memory data used for takeover judgments. Rymvard lists contact@rymvard.com for inquiries. The company has not disclosed a timeline for moving beyond early access.
