Top Ten Questions to Ask Your Storage Provider about Data Efficiency: Question #10 - How Mature is Your Offering

| By: (9)

Question 10: How mature is the code or product offering and is the solution available in a format that integrates easily with your products? Best Answer: Commercially deployed for over 5-10 years and available in multiple formats with varying levels of integration and configurability. Why this matters: Protecting data integrity is a key requirement for primary storage. Deployment of technologies that have not been proven in production introduces a significant…

Top 10 Questions to Ask your Storage Vendor about Data Efficiency: Question #9 – What’s Your HA Strategy?

| By: (9)

Question 9: What is your high availability (HA) strategy? Best Answer: Fully separate appliances deployed on separate data paths. Why This Matters: Data availability is a hallmark of enterprise storage. Users employ redundant drives, redundant paths, and clustered servers to ensure data is available 24/7. If your storage appliance lacks an HA configuration, (e.g., clusters of at least two appliances) data outages can last hours or days depending upon the…

Top 10 Questions to Ask your Storage Provider about Data Efficiency: Question #8 – Where Do You Store Metadata?

| By: (9)

Question 8: Is metadata kept persistent in non volatile memory or on disk? Best answer: Metadata is kept persistent and local with the data at all times. Why this matters: Metadata is non-user data created during the deduplication process. Metadata is the “Rosetta stone” used to reconstruct original user data files. All metadata modifications must be kept persistent at the risk of catastrophic data loss. Systems that store metadata in…

Top 10 Questions to Ask Your Storage Provider about Data Efficiency: Question #7 – HA Recovery Time

| By: (9)

Question #7: How long does your appliance take to bring a volume back online after a power failure? Best Answer: 10 seconds or less Why this matters: Whether it’s due to physical events or improper management practices, any hardware can shut down unexpectedly. As a result of an unplanned shutdown, a data efficiency appliance will perform a series of actions before the volume can be brought back on line. If…

Top 10 Questions to Ask Your Storage Provider about Data Efficiency: Question #5

| By: (9)

This is the fifth post in our weekly series on the “Top 10 Questions to ask your Storage Provider about Data Efficiency” Question #5: How far back can your product recall seeing a 4 KB data block? Best Answer: 256 TB or more Why this matters: All deduplication algorithms must keep a list of previously stored data blocks. As this list grows, many algorithms have trouble managing it efficiently. A…

Top 10 Questions to Ask Your Storage Provider about Data Efficiency: Question #4 – Compression and Dedupe?

| By: (9)

Question 4: Does your product combine block level compression with deduplication? Best Answer: Yes. Compression and deduplication are complementary data efficiency technologies. Why this matters: Many datasets see 2X data reduction from block-level compression techniques. However, when compression is combined with block-level deduplication, the benefits are magnified by as much as 17X. ESG Labs research shows that this is especially true in environments where large amounts of redundant data are…

Top Ten Questions about Data Efficiency: Question #3 Hashing Algorigthm

Top 10 Questions to Ask Your Storage Provider about Data Efficiency: Question #3 – Hashing Algorithm

| By: (9)

Question 3: What algorithm do you use for hashing and do you require any special hardware? Best answer: Support is provided for both hardware-assisted and software-only approaches. Why this matters: Deduplication algorithms employ content hashing to recognize duplicate blocks. Hashing maps the content of a block to a concise value. SHA-256 is known as a cryptographic hash, and will produce a match only if two blocks match exactly. Using SHA-256…

Top 10 Questions to Ask your Storage Provider about Data Efficiency: Question #2 – Inline or Post-Process?

| By: (9)

Question #2: Does your deduplication occur inline or post-process? Best Answer: Inline When choosing data efficiency software, one of the main decisions you’ll need to make is whether to opt for inline or post-process deduplication. Simply put, the difference between the two lies in when they process data to remove duplicates.   Why This Matters: Inline deduplication looks for duplicate blocks of data as data is ingested to the target…
