Understanding UPS redundancy topologies for data centers

Are you running #CiscoUCS in a single domain and seeking maximum simplicity? We are drastically reducing complexity and TCO by connecting #PureStorage #FlashArray and #FlashBlade directly to Cisco UCS Fabric Interconnects (X-Series) This deployment eliminates dedicated switches for storage connectivity, supporting a comprehensive range of data services: #FlashArray: File (NFS/SMB) #FlashBlade: High-Performance File (NFS/SMB) and Object (S3) Whether you manage your environment with #CiscoIntersightManagedMode or #UCSManager, these guides provide the path to a simpler, high-performance data platform.

NetApp ONTAP Scenario — Understanding High Availability (HA) Data Serving * If nodes 1 and 2 in an HA pair go down, but nodes 3 and 4 are still up, how can the volume continue to serve data from nodes 3 and 4? Explanation: In a NetApp ONTAP cluster, data availability depends on HA pairing and aggregate ownership. Each HA pair (for example, Node 1 ↔ Node 2, Node 3 ↔ Node 4) has mirrored storage aggregates that protect against node or controller failures within that pair. If both nodes in an HA pair (1 and 2) are down, their aggregates and volumes become unavailable — because no partner node exists to take over ownership of those aggregates. However, nodes 3 and 4, which form another HA pair, remain operational and continue to serve data from their own volumes without interruption. #NetApp #ONTAP #StorageEngineer #DataAvailability #HighAvailability #Networking #ITInfrastructure #LearningJourney

From Tier I to Tier IV: What Redundancy Really Looks Like The Uptime Institute created the Tier classification system to standardize how we measure redundancy and uptime in data centers. It ranges from Tier I (basic) to Tier IV (fault tolerant). Each Tier adds more redundancy — and more uptime. Tier 1-2 are non commercial data centers which are not certified. Tier 3 onwards ,they are certified Data Centers with more uptime. Tier III – Concurrently Maintainable Multiple distribution paths N+1 redundancy Can maintain systems without shutting down ~99.98% availability (~1.6 hours downtime/year) Tier IV – Fault Tolerant 2N or 2(N+1) redundancy Independent power & cooling paths Can withstand unplanned failures without impact ~99.995% availability (~26 minutes downtime/year) If you were designing a new facility, which Tier would you aim for? 💡 #DataCenter #CriticalInfrastructure #Redundancy #Uptime #TierIII #TierIV #EngineeringLife #FacilityOps

Faster. Smarter. More reliable SQL performance. Our latest reference architecture shows how combining Hitachi VSP One Block with HA820 G3 servers transforms Microsoft SQL Server environments — delivering high throughput, low latency, and 344K IOPS in benchmark tests. If you’re modernizing your database infrastructure, this is what performance and efficiency should look like. #HitachiVantara #SQLServer #DataInfrastructure #Performance https://lnkd.in/ecGDUti6

Today's deep dive focused on how to keep these massive digital ecosystems secure and manageable: #Focus: Mastering Disk Management for secure and reliable server operations. #Partitioning: Learned the roles of primary, extended, and logical partitions. #Volume_Types: Gained expertise in server volume configurations: simple, spanned, stripped (RAID 0), mirrored (RAID 1), and full RAID setups. #Security_Insight: Understood how these configurations, plus proper disk management, ensure data is secure, manageable, and highly recoverable in real-time servers/data centers. This knowledge is fundamental to keeping the digital world running securely! #DataCenter #DiskManagement #RAID #DataSecurity #ServerAdministration #ITInfrastructure #TechLearning

⚙️ Understanding Cluster & High Availability (HA) in IT Infrastructure In modern IT environments, downtime is not acceptable — that’s where Cluster and HA (High Availability) come in. 💡 What is a Cluster? A cluster is a group of servers that work together as a single system. If one server fails, another automatically takes over — keeping systems online without interruption. 💡 What is HA (High Availability)? High Availability ensures that your applications and services remain accessible even during hardware or software failures. It minimizes downtime through redundancy, failover, and load balancing. ✅ Key Benefits: Continuous uptime for business-critical apps Automatic failover and resource sharing Better performance and load distribution Reduced maintenance impact In short, Cluster + HA = Reliability, Continuity, and Confidence. Every modern data center depends on these technologies to deliver 24/7 services. #HighAvailability #Cluster #DataCenter #ITInfrastructure #SystemAdmin #Technology

Many people still get confused between RDM and VMDK in vCenter 👇 🔹 VMDK (Virtual Machine Disk) is a regular virtual disk stored as a file inside the datastore. It supports features like snapshots and vMotion, and it’s perfect for most daily workloads. 🔹 RDM (Raw Device Mapping) directly connects a physical LUN from the storage to a virtual machine, bypassing the virtual storage layer. It’s mainly used when you need high performance or clustering setups (like SQL or Oracle RAC). 💡 In short: VMDK = Virtual disk file RDM = Direct physical disk connection #VMware #vCenter #Virtualization #RDM #VMDK #Tech #IT
