ObjectScale XF960

Fresh off the launch of the new ObjectScale 4.1 release, Dell Technologies has announced the general availability of the ObjectScale XF960 platform, a next-generation all-flash object storage appliance designed to meet the performance demands of AI, analytics, and unstructured data workloads. The XF960 is now ready to ship, offering a compelling blend of speed, scalability, and efficiency.

Built to support performance-driven workloads, the XF960 enables organizations to unlock the full potential of their data. Whether training complex AI models, managing large datasets, or deploying cloud-native applications, the XF960 provides the object storage substrate needed to drive innovation.

As Dell’s highest-performing object storage platform to-date, the new XF960 delivers up to 300% more read throughput, 42% more write throughput, plus 75% lower read and 42% lower write response times than the previous-generation EXF900.

The XF960 scales effortlessly from small clusters to large enterprise deployments, maintaining performance and manageability throughout. It also introduces advanced data efficiency features, including five user-configurable compression modes—LZ4, Zstandard, and Deflate among them—allowing for up to a 9:1 compression ratio on certain workloads.

Enhancing its S3 protocol compatibility, the XF960 supports push-based event notifications, up to three times faster object listing, S3FS file system mounting, and seamless integration with the latest AWS SDKs, improving both data access and developer productivity.

Designed for flexible integration, the XF960 accommodates the expansion of existing ECS environments, and is initially supported with the new ObjectScale 4.1 code which dropped last week (8/12/25).

As compared to the EXF900, the XF960 features up-rev’d hardware, including a 2RU PowerEdge R760 chassis, dual Intel Sapphire Rapids CPUs with 32 cores, 256GB DDR5 memory, and support for NVMe drives ranging from 7.68TB to 61.44TB. It also includes 100GbE front-end and back-end NICs, dual 1400W power supplies, and S5448 switches.

For existing ObjectScale all-flash customers, while it is technically possible to intermix EXF900 and XF960 nodes, it is not recommended due to performance limitations. Mixed clusters will operate at EXF900 performance levels. That said, the  next ObjectScale release, v4.2, will introduce improvements for mixed environments.

ObjectScale 4.1

Hot off the press comes ObjectScale version 4.1 – a major release of Dell’s enterprise-grade object storage platform. As a foundational component of the Dell AI Data Platform, ObjectScale 4.1 delivers enhanced scalability, performance, and resilience that’s engineered to meet the evolving demands of AI-driven workloads and modern data ecosystems.

This release is available as a software upgrade for existing ECS and ObjectScale environments, and the core new features and functionality introduced in this ObjectScale 4.1 release include:

Storage Efficiency and Operational Experience

On the storage efficiency and operation experience front, ObjectScale 4.1 introduces support for multiple compression modes including LZ4, Zstandard, Deflate, and Snappy, configurable via both the UI and API. This flexibility allows admins to fine-tune compression strategies to balance performance, cost, and workload characteristics.

Post-upgrade to ObjectScale 4.1, the default algorithms are updated to LZ4 for AFA appliances (EXF900 and XF960) and Zstandard for HDD appliances (EX300, EX3000, EX500, EX5000, X560). Storage admins can change the algorithm at any time via the UI or API, based on workload or use case.

Improved garbage collection throughput enables faster reclamation of deleted capacity. Enhanced monitoring, alerting, and logging tools provide greater visibility into background processes, contributing to overall cluster stability.

An updated dashboard offers refined views of user, available, and reserved capacity. Automated alerts notify administrators when usage exceeds 90%, indicating a transition to Read-Only mode for the affected Virtual Data Center (VDC).

New port-level bandwidth controls for replication traffic allow for more predictable performance and optimized resource allocation across distributed environments.

Security and Data Protection

Within the security and data protection realm, ObjectScale now provides support for Self-Encrypting Drives (SEDs) with local key management via Dell iDRAC. This ensures hardware-level encryption and secure, appliance-local key handling for enhanced data protection.

TLS 1.3, the latest version of the Transport Layer Security protocol, is also supported in ObjectScale 4.1. This upgrade delivers stronger encryption, faster handshakes, and the removal of legacy algorithms, improving both control and data path security.

Expanded Capabilities for Modern Workloads

ObjectScale 4.1 now offers up to 3x faster object listing performance in multi-VDC environments. This enhancement improves data browsing and discovery, with better handling of deleted metadata and validation of Untrusted Listing Keys.

Through webhook-based APIs, ObjectScale can now push real-time notifications to external applications when events such as object creation, deletion, or modification occur—enabling responsive, event-driven architectures.

Support for S3FS in 4.1 allows users to mount S3 buckets on Linux systems as local file systems. This simplifies access and management, particularly for legacy applications that rely on traditional file system operations.

On the integration front, ObjectScale 4.1 is compatible with the latest AWS SDK v2.29, so Java developers can immediately use new S3 features and performance fixes in their applications, and build cloud-native applications with full access to modern AWS features and APIs.

The following hardware platforms are supported by the new ObjectScale 4.1 release:

Gen 2 systems U480E, U400T, U400E, U4000, U400, U2800, U2000, D6200, D5600, D4500
Gen 3 systems EX3000, EX300, EXF900, EX5000, EX500
Gen 4 systems X560, XF960

Note that upgrading to ObjectScale 4.1 is only supported from ECS 3.8.x and 4.0.x releases.

In summary, ObjectScale 4.1 represents a strategic advancement in Dell’s commitment to delivering intelligent, secure, and scalable storage solutions for the AI era. Whether upgrading existing infrastructure or deploying new systems, this new 4.1 release empowers organizations to meet the challenges of data growth, complexity, and innovation with confidence.
