SERVER SMACKDOWN: RACKS VS. BLADES VS. HYPERCONVERGED
Which Technology Will Exit The Octagon Victorious?
2| SERVER SMACKDOWN | DECEMBER 8, 2015
RACKS VS. BLADES VS. HYPERCONVERGED
Three competing physical server architectures
Blade servers
Rack servers
Hyperconverged servers
3| SERVER SMACKDOWN | DECEMBER 8, 2015
RACK 'EM AND STACK 'EM: RACK SERVERS
Rack servers were the first attempts to increase DC server density Commonly found in many SMB server rooms and enterprise DCs Allow for easy hardware upgrades and reconfiguration Offer widest variety of server hardware configs
4| SERVER SMACKDOWN | DECEMBER 8, 2015
DOUBLE-EDGED SWORDS: HIGH-DENSITY BLADE SERVERS
Provide maximum physical server density Ideal for physical server clustering
Common architecture in cloud computing and enterprises Can max out DC resources (cooling, power, network)
5| SERVER SMACKDOWN | DECEMBER 8, 2015
HYPERCONVERGED: PUTTING THE HYPE IN HYPERCONVERGED
Combine compute, network and storage in same chassis Tight integration means easier to deploy and manage, higher
performance Ideal for remote or smaller offices
Integrated management console

MORE ON HYPERCONVERGED SERVERS
Hype or not, hyperconverged has advantages Can lose a large % of useable storage to redundancy
Use various schemes to pool and cluster services Hyperconverged servers may not integrate with
legacy servers
7| SERVER SMACKDOWN | DECEMBER 8, 2015
EVALUATING SERVER TECHNOLOGIES
Where each architecture shines (or doesn’t)
Matching architecture to workloads
Performance metrics and comparisons
Physical vs. virtual servers
8| SERVER SMACKDOWN | DECEMBER 8, 2015
REDUNDANCY AND RESILIENCY IN THE RACK AND BLADE WORLD
Most rack and blade servers use OS-based redundancy schemes
Cluster/load balance your critical servers and storage Some offer proprietary resiliency Be sure to include networking redundancy
9| SERVER SMACKDOWN | DECEMBER 8, 2015
Most hyperconverged servers offer clustering
Distributed storage can be harder to manage
Specific backup/restore planning may be required
Keep spare chassis onsite for redundancy
REDUNDANCY AND RESILIENCY IN A HYPERCONVERGED WORLD
10| SERVER SMACKDOWN | DECEMBER 8, 2015
EVALUATING STORAGE CAPACITY IN HYPERCONVERGED SERVERS
Quoted capacity is not practical capacity with resiliency
Erasure coding vs. RAID Test and understand failover and failback capabilities
Distributed storage can complicate backup/restore
11| SERVER SMACKDOWN | DECEMBER 8, 2015
BEST PRACTICES FOR IMPLEMENTING RACK SERVERS
Plan your physical and logical implementation Rack servers can be ordered preconfigured Use traditional clustering and failover technology Be mindful of physical installation requirements Keep spare chassis on hand when possible
12| SERVER SMACKDOWN | DECEMBER 8, 2015
BEST PRACTICES FOR IMPLEMENTING BLADE SERVERS
Examine your DC resources carefully Track your blade server configs and workloads Hot spares are usually an option Keep cold spare blades in stock regardless
13| SERVER SMACKDOWN | DECEMBER 8, 2015
BEST PRACTICES FOR IMPLEMENTING HYPERCONVERGED SERVERS
Plan carefully as hyperconverged servers are not as flexible Spare chassis may be useful to support physical redundancy Distributed storage may have specific backup requirements Hyperconverged servers may support WAN replication

AND THE WINNER IS…
Best technological fit Best bang for your budget bucks Best hi-density computing fit Easiest to implement and manage
