Stacbloc HCA runs Compute workloads as Virtual Machines on top of Hypervisor layer. The underlying hardware architecture is x64 / x86, which supports all Server and Client Operating Systems such as Windows, Linux, FreeBSD. Customers run business critical solutions like ERP, CRM, Live Media Playout, Internet of Things, Core Banking 24 x 7 on Stacbloc. Besides, pre-built virtual appliances like load balancer, traffic manager, network gateway, security appliance, replication engine, wan optimizer, cloud gateway run on Stacbloc.
Stacbloc has in built Storage engine that runs IP SAN (Storage Area Network), NAS (Network Attached Storage) and automated replication engine. Block Storage access via iSCSI and File Services via FTP, CIFS, SMB, NFS meets all standard storage needs. Integration of CEPH and DRBD protocols right into the Hypervisor helps to build highly available storage services across hosts. Right balance of SSD and HDD creates optimal storage solution, which serves live data storage, backup and archive purposes.
Stacbloc has integrated network services engine which does L3 Routing and L2 switching functionalities. All industry standard protocols that are used in Telecom Service Providers and Enterprise class network infrastructure are supported. Switching functionalities allow Physical-to-Virtual and Virtual-to-Virtual traffic flow. Routing functionalities allow LAN-to-WAN traffic flow. All traffic flow is controlled by inbuilt customized security policies.
Stacbloc ‘s hardware has Gigabit and 10 Gigabit Ethernet network ports that receives WAN terminations like Internet, Private Leased Circuits. Stacbloc’s routing engine runs all standard network routing protocols like BGP, OSPF, RIP, PBR, VRRP etc. Stacbloc can be deployed as core or edge router and avoids need of physical router.
Stacbloc has inbuilt network security features like Stateful firewall, NAT, Proxy, VPN, Web filtering, Geo IP filtering, Blacklisting, DNSBL, IDS IPS etc. Security engine allows to create policies to permit inter VM traffic flow.

Staff of Engineering team at Stackup Tech or from authorized partner would install and commission Stacbloc, from rack mounting to services going live. The necessary infrastructure configurations in terms of VM creation, compute, turning on storage with necessary sizes and rights, network configuration to create traffic flow and configuring security rules inlines with the policies needed would be done on-site. All that are part of infrastructure readiness will be tested, validated on-site and will be handed over to customer and support NOC.
Generic infrastructure readiness in terms of space, power, cooling, cabling are expected to be provided from customer end. Deployment details in terms of VM resources, IP addresses, storage spaces, user rights shall be provided by customer. Beyond which, the scope rests with Stackup Tech authorized field engineer.
Stackup Tech engineering team will implement and support entire IT infrastructure portion with respect to Stacbloc, however the virtual machines in compute engine shall be under the purview of customer.
Customer support is handled via remote and on-site. Customer could raise trouble tickets via e-mail (firstname.lastname@example.org), web (www.stackuptech.com/support) or voice (+91 44 46200100). Support Engineers would help in getting the technical problems sorted out. Field engineers would visit the customer site for fixing any issues that couldn’t be solved remotely.
Managed services option is provided to customer, wherein Stackup Tech engineering team will take care of one time installation, on-going configuration changes, periodic health check, operation & management and support services.
Stackup support is of two types – Standard support and Premium support.
